Full textAbstract:
Waterproofing is an essential component in building construction to maintain the integrity of buildings with reduced maintenance cost. A comprehensive waterproofing system is an integrated combination of factors, and includes product selection, membrane detail, substrate preparation, design, installation and maintenance. It is designed to work under different environmental conditions, substrates and applications. Proper understanding of the issues related to waterproofing membrane systems is important to minimise the waterproofing failures in both commercial and residential buildings. This paper aims to discuss Standards and Codes; membrane systems and performance, waterproofing practices, design and installation techniques, inspection and testing and quality assurance adopted by the waterproofing industry in Australia.

The use of Engineered Wood Systems (EWS) as structural alternatives or complements of traditional materials, such as steel and concrete, is of growing interest and acceptance in the architecture, engineering, and construction industries. Gathering evidence from the Australian context, this paper proposes a roadmap for the adoption of EWS as the primary structural materials of medium-rise buildings, with the scope of increasing levels of public awareness about the potential and current shortcomings of these building technologies. A nation-wide survey with stakeholders at the forefront of adoption in structural design, construction, and property development, indicates that the demand for timber in multi-storey projects has promising prospects of growth, but faces circumstantial industry-wide hurdles in the short to medium term. Awareness of benefits and inclination towards more use of timber among designers are positive factors that provide a promising base for further adoption. The translation of positive front-end design attitudes into adoption, however, requires holistic long-term investment efforts with industry-wide education. The pathway to innovation for timber in multi-storey projects needs to grow beyond mere promotional strategies of its benefits, seeking to expand technical knowledge through education and reaching out beyond a group of already committed and knowledgeable stakeholders at the forefront of adoption.

Abstract In the extreme climates of Australia, rural and remote locations have special site and dwelling requirements and therefore special design solutions. This can include construction constraints, bushfire risk, resource efficiency, comfort and respect for the surrounding environment and heritage. Existing regulations targeted at extreme weather impacts such as bushfire, flood, cyclones, and heatwaves often impact the design and material choices for rural and remote housing due to their exposed locations, including housing proposed for rebuild following damage resulting from an extreme weather event. These regulations also lead to increased costs and uncertainty about the suitability of rural land for construction, making it challenging for rebuilding communities in affected areas. Such well-intentioned regulations also create limitations on innovation through experimental / bespoke building design, such as; 1) novel solutions to extreme weather mitigation and resistance 2) material choices for construction; and 3) achievement of operational and embodied energy reductions. Experimental buildings provide significant innovation benefits to industry as is often seen in the development of sustainable and high-performance buildings. This research examines the academic and industry knowledge of current design regulations for extreme weather events and implications for experimental and innovative design, highlighting the challenges for buildings to achieve increasing standards of environmental performance whilst ensuring resilience in the face of increasing extreme weather events, with a specific focus on rural communities. Case study analysis is used to provide an understanding of the focus and strategies used by different groups in different locations to address the impacts of extreme weather.

Purpose – This paper aims to identify the critical issues to be considered by developers and practitioners when embarking on their first green residential retirement project in Australia. With an increasingly ageing population and widespread acceptance of the need for sustainable development in Australia, the demand for green retirement villages is increasing. Design/methodology/approach – In view of the lack of adequate historical data for quantitative analysis, a case study approach is used to examine the successful delivery of green retirement villages. Face-to-face interviews and document analyses were conducted for data collection. Findings – The findings of the study indicate that one of the major obstacles to the provision of affordable green retirement villages is the higher initial costs involved. However, positive aspects were identified, the most significant of which relate to the innovative design of site and floor plans; adoption of thermally efficient building materials; orientation of windows; installation of water harvesting and recycling systems, water conservation fittings and appliances; and waste management during the construction stage. With the adoption of these measures, it is believed that sustainable retirement development can be achieved without significant additional capital costs. Practical implications – The research findings serve as a guide for developers in decision-making throughout the project life-cycle when introducing green features into the provision of affordable retirement accommodation. Originality/value – This paper provides insights into the means by which affordable green residential retirement projects for aged people can be successfully completed.

Building Services Engineering Research and Technology 38, no. 6 (June 4, 2017): 711–27. http://dx.doi.org/10.1177/0143624417711343.
Full textAbstract:
The paper describes the transformation that has taken place over the last 15 years in the energy efficiency of new office buildings constructed in Australia and considers if and how the UK could follow suit. The success in Australia has been greatest for the ‘base building’: the energy performance of the HVAC services in tenanted spaces and of all end uses in the common parts. It embraces a ‘ design for performance’ culture, supported by the NABERS ‘Commitment Agreement’, where developers and their teams sign up to an in-use performance target. The process is underpinned by advanced simulation, strategic sub-metering and fine-tuning post occupation to help eliminate wasteful deviations. The paper considers the opportunity for the UK to introduce a Commitment Agreement process for new office buildings, integrated with the Soft Landings Framework. It is argued that from a technical perspective base building energy performance in new UK offices could be as good as it is in Australia. However, there are non-technical drivers missing in the UK. To compete with their Australian peers, the UK property and construction industries need a base building energy measurement and rating system, creating the ability to set a performance target and disclose the outcome. Practical application: Design for performance uses a much more realistic building simulation model at the design stage. Although this requires a lot more inputs (details of the building’s proposed chillers, AHUs, ducts and valves, etc. and their controls), it enables the designers to capitalise from computer-aided-design to improve energy efficiency. This process deploys the technology improvement template by which much of the modern world has progressed so fast, and enables innovation to flourish. The more advanced HVAC model can predict target energy budgets for each sub-system (boilers, chillers, fans, pumps, etc.) against which the actual energy used, as measured with sub-meters, can be compared to inform fine tuning during early operation. Although a model’s predictions can be considered the ideal energy performance of the as-built system, there’s an expectation that the base building’s real performance should turn out to be within around 10% of that anticipated from the modelling.

Full textAbstract:
As woodworking and construction technologies improve, the construction of multi-storey timber buildings is gaining popularity worldwide. There is a need to look at the design of existing buildings and assess their sustainability. The aim of the present study is to assess the sustainability of modern high-rise timber buildings using multi-criteria assessment methods. The paper presents a hierarchical system of sustainability indicators and an assessment framework, developed by the authors. Based on this framework, the tallest timber buildings in different countries, i.e., Mjøstårnet in Norway, Brock Commons in Canada, Treet in Norway, Forte in Australia, Strandparken in Sweden and Stadthaus in UK, were compared across the three dimensions of sustainability (environmental, economic/technological, and social). Research has revealed that none of the buildings is leading in all dimensions of sustainability. However, each building is unique and has its own strengths. Overall multi-criteria assessment of the buildings revealed that the Brock Commons building in Canada has received the highest rank in all dimensions of sustainability. The paper contributes to the theory and practice of sustainability assessment and extends the knowledge about high-rise timber buildings. The proposed sustainability assessment framework can be used by both academics and practitioners for assessment of high-rise timber buildings.

Full textAbstract:
National design guides provide essential guidance for the design of building drainage systems, which primarily ensure the basic objectives of preventing odor ingress and cross-transmission of disease through water-trap seal retention. Current building drainage system design guides only extend to buildings of 30 floors, while modern tall buildings frequently extend to over 100 floors, exceeding the predictive capability of current design guides in terms of operating system conditions. However, the same design guides are being used for tall buildings as would be used for low-rise buildings. A complicating factor is the historic roots of current design guides and standards (including the interpretation of the governing fluid mechanics principles and margins of safety), causing many design differences to exist for the same conditions internationally, such as minimum trap seal retention requirements, stack-to-vent cross-vent spacing, and even stack diameter. The design guides also differ in the size and scale of the systems they cover, and most make no allowance for the specific building drainage system requirements of tall buildings. This paper assesses the limitations of applying current building drainage system design guides when applied to the case of tall buildings. Primarily, the assessments used in this research are based on codes from Europe, the USA and Australia/New Zealand as representative of the most common approaches and from which many other codes and standards are derived. The numerical simulation model, AIRNET, was used as the analysis tool. Our findings confirm that current design guides, which have been out of date for a number of decades, are now in urgent need of updating as code-compliant systems have been shown to be susceptible to water-trap seal depletion, a risk to cross-transmission of disease, which is a major public health concern, particularly in view of the current COVID-19 pandemic.

Full textAbstract:
Purpose – The purpose of this paper is to explore the barriers preventing investment in the re-use of low-grade multi-storey building stock in order to identify attributes that determine whether an existing building is suitable for retrofitting. Design/methodology/approach – Semi-structured interviews were undertaken with key industry practitioners to investigate existing practices and barriers facing low-grade building retrofits and what “ideal” multi-storey building features represent a successful investment opportunity. Findings – The findings showed that tenant commitment is necessary before any project goes ahead and that there exist many barriers influencing the investment decision. These include: high levels of asbestos found in existing buildings; changes in the National Construction Code necessitating enhanced fire safety and disability access; heritage listing; lack of awareness; overestimation of costs involved on simple and effective energy efficiency upgrades and change in tenant demands towards modern and efficient open plan offices. Many low-grade structures are privately owned inherited assets where the owners lack the expertise and capital to undertake retrofitting effectively. Research limitations/implications – The study is focused on the Adelaide CBD in South Australia but the findings are relevant to other Australian cities. Practical implications – There is room in the market for more positive and influential schemes such as the Green Building Fund that encourage more energy efficiency upgrading of these buildings. Social implications – The greater occurrence of retrofitting and re-use of older buildings, rather than demolition and rebuilding, has advantages with regard to reducing the impact of buildings on the environment and promoting sustainability. Originality/value – The research has indicated certain features of older buildings which render them as suitable candidates for retrofitting and refurbishment.

Abstract In Australia, one-third of new constructions are affected by condensation and about 50% of buildings suffer from mould risk, mainly due to inappropriate design and management strategies. Despite the potential structural damage and serious health hazards, there is a lack of preventive moisture management strategies at the legislative level. The first hygrothermal management provisions were adopted in the National Construction Code only in 2019, with very general indications that correlate the breathability of the membranes with the climate zone. However, the building code identifies only eight zones for the entire Australia, which were originally developed for thermal analysis and energy efficiency provisions. The result is a coarse climate grid that clusters locations with highly variable humidity conditions. This paper undertakes a semi-empirical approach to identify whether the current climate zones are suitable for hygrothermal purposes. This research represents the first step towards an Australian-specific moisture risks management framework, and it advances the discussion about the suitability of the current hygrothermal design and construction policy and practices. The outcomes reveal the highly variable moisture indices obtained for the different representative cities, affirming the inappropriate use of existing climate zone clustering for hygrothermal assessment purposes.

Purpose The purpose of this paper is to present outcomes from a post-occupancy evaluation (POE) of a sustainable university building development. Design/methodology/approach A POE was conducted for a sustainable university building in Melbourne, Australia. The method included interviews with key stakeholders involved in the design, construction and occupation of the building. The interviews were complemented by conducting a Builder User Satisfaction survey and analysis of two year’s worth of building performance data. Findings While technically the building saw a significant improvement in performance in comparison to existing buildings at the university, it ultimately did not meet its design performance goals as determined by the design rating. The interviews revealed limited formal documenting of lessons learnt and the challenges associated with using a sustainable and innovative building to drive cultural change. A major success was the realisation by the university of the benefits that the systematic POE provided. Lessons are now being applied to other new and refurbished buildings on campus, with POE now an integrated part of these processes. Originality/value While there are some studies of sustainable university operations and buildings, many focus on one or two parts of the process and fail to include evaluation of the full sustainability approach to check if stated goals have been met. This paper begins to address this gap. Learnings from the research are applicable to the wider building development industry and demonstrate the important role universities can play in shaping the sustainability of urban environments.

Full textAbstract:
The uptake of buildings employing cross-laminated timber (CLT) assemblies and designed to Passivhaus standard has accelerated internationally over the past two decades due to several factors including responses to the climate crisis by decarbonising the building stock. Structural CLT technology and the Passivhaus certification both show measurable benefits in reducing energy consumption, while contributing to durability and indoor comfort. However, there is a general lack of evidence to support a fast uptake of these technologies in Australia. This paper responds to the compelling need of providing quantitative data and adoption strategies; it explores their combined application as a potential pathway for climate-appropriate design of energy-efficient and durable mass timber envelope solutions for subtropical and tropical Australian climates. Hygrothermal risk assessments of interstitial condensation and mould growth of CLT wall assemblies inform best-practice design of mass timber buildings in hot and humid climates. This research found that the durability of mass timber buildings located in hot and humid climates may benefit from implementing the Passivhaus standard to manage interior conditions. The findings also suggested that climate-specific design of the wall assembly is critical for mass timber buildings, in conjunction with excellent stormwater management practices during construction and corrosion protection for metallic fasteners.

Full textAbstract:
Design for manufacture and assembly (DfMA) is an important part of the future of the construction industry due to the promise of speed of project delivery, quality control, worker safety, and waste minimization onsite via the purposeful design for manufacture and assembly offsite. However, the adoption of DfMA in Australia has been slow. This paper investigates the barriers prohibiting widespread uptake and how digital construction will be a catalyst for improving use on commercial-scale projects. A total of six leading experts were interviewed to elicit their opinions, and seven recent case studies of high-rise modular apartment and hotel buildings constructed by Hickory were cross-referenced as evidence of DfMA capability. The experts suggested that the reasons for slow adoption in Australia were community mindset, government regulations and incentives, planning and building codes, unionization and business politics, finance, and supply chain management. The case studies suggest that compatible building type and transportation distance are also factors. These barriers can be addressed by the clever integration of building information modelling tools with lean construction processes as part of a proposed strategy leading to smarter (more productive) and better (more sustainable) outcomes predicated on growth in digital construction practices. The paper concludes with a proposed framework for change that conceptualizes the ‘ecosystem’ needed to support widespread DfMA in the Australian context, including the paradigm shift from building to manufacturing/assembly, the displacement of workers from onsite to offsite activity, and the expansion of interdisciplinary design and construct collaboration.

Ten days after the Newcastle, Australia earthquake of 28 December, 1989, the UK-based Earthquake Engineering Field Investigation Team (EEFIT) mounted a five day mission to the affected area. This paper presents the findings of the EEFIT investigation and subsequent follow up studies in relation to the extent of building damage and its distribution within the City of Newcastle and the surrounding urban area. Results are based on both detailed street surveys and general damage surveys, the former carried out in two areas, namely the heavily damaged suburban district of Hamilton (3km west of the city centre) and the Newcastle central business district. The findings of these surveys have provided valuable information on the vulnerability of building stock of types common to other parts of Australia, the UK and elsewhere, and hence form an important database for the accurate assessment of seismic risk to buildings in regions of low seismicity. This information will assist the development of realistic, economical seismic code provisions for building design and construction in low-risk areas. An important feature arising from the surveys and subsequent analytical studies of site response in the heavily damaged districts within the Hunter River alluvial basin is that, contrary to reports published by the Institution of Engineers, Australia amongst others, the areas of deep alluvial soil and fill do not correlate strongly with the more heavily damaged districts determined from post-earthquake assessments. Hence, suggestions that this form of site soil amplification effect played a major part in the distribution and extent of heavy damage in this earthquake are somewhat misleading for the future development of planning and design regulations. Furthermore, the results of site response analyses show that it is more likely to be the shallower soils near the border of the alluvial basin which tend to amplify bedrock ground motions generated by this type of earthquake.

Full textAbstract:
Construction and demolition waste (C&DW) contribute to approximately 30% of the total waste generation worldwide, by which heterogeneous ecological impacts, such as resource depletion, global warming, and land degradation, are engendered. Despite ongoing research efforts to minimize construction waste via the Building Information Modeling (BIM)-aided design, there is a paucity of research on integrating BIM in demolition waste management (DWM). This study investigates prominent barriers and future research directions toward the wider adoption of BIM in C&DWM by conducting a systematic literature review. First, this study identifies the barriers that hinder the implementation of C&DWM in Australia; then, it explores the benefits and challenges of leveraging BIM applications for C&DWM. The findings suggest that, for existing buildings without up-to-date design drawings, it is imperative to improve the accuracy of data capturing and object recognition techniques to overcome the bottlenecks of BIM-DWM integration. Moreover, the development of regional-oriented material banks and their harmonization with life cycle assessment databases can extend the potential of BIM-based sustainability analysis, making it applicable to the DWM domain. This study proposes a research agenda on tackling these challenges to realize BIM’s full potential in facilitating DWM.

Abstract The building envelope is the boundary between the outer and inner spaces and it is considered as the most significant part in the process of preservation of internal spaces cooling energy consumption. In this context, it is argued that the weakest point in the envelope with the highest transmittance of thermal energy into and out of the internal spaces is the openings (windows and doors) which are affected by many factors such as their ratio, material thermal properties and construction. Therefore, this study sheds light on the alternatives of the envelope design generated with the help of a computer-based simulation tool, Design-Builder, as it has great possibilities for creating simulated scenarios for a specific building or space by linking these scenarios with specific changes in the building parameters. Thus, the study will focus on creating different scenarios for a selected classroom in the College of Arts and Design at Princess Nourah bint Abdulrahman University (Riyadh, KSA), with the aim of associating the openings ratios (20%, 30%, 50%, 100%) with wall thickness (12 cm, 25 cm solid brick, 25 cm hollow brick) and energy consumption. Optimum alternatives for the opening ratio and construction materials with the lowest cooling loads during working hours are proposed.

Abstract. Australia is vulnerable to the impacts of tsunamis and exposure along the SE coast of New South Wales is especially high. Significantly, this is the same area reported to have been affected by repeated large magnitude tsunamis during the Holocene. Efforts are under way to complete probabilistic risk assessments for the region but local government planners and emergency risk managers need information now about building vulnerability in order to develop appropriate risk management strategies. We use the newly revised PTVA-3 Model (Dall'Osso et al., 2009) to assess the relative vulnerability of buildings to damage from a "worst case tsunami" defined by our latest understanding of regional risk – something never before undertaken in Australia. We present selected results from an investigation of building vulnerability within the local government area of Manly – an iconic coastal area of Sydney. We show that a significant proportion of buildings (in particular, residential structures) are classified as having "High" and "Very High" Relative Vulnerability Index scores. Furthermore, other important buildings (e.g., schools, nursing homes and transport structures) are also vulnerable to damage. Our results have serious implications for immediate emergency risk management, longer-term land-use zoning and development, and building design and construction standards. Based on the work undertaken here, we recommend further detailed assessment of the vulnerability of coastal buildings in at risk areas, development of appropriate risk management strategies and a detailed program of community engagement to increase overall resilience.

Full textAbstract:
Purpose The short life cycle replacement of fitout in modern high-rise office buildings represents an under-researched waste problem. This paper aims to quantify the amount of demolition waste from office strip-out including attention to waste streams going to landfill, reuse and recycling. Design/methodology/approach Quantitative waste data (by weight) were measured from 23 office fitout projects situated in “A” grade office building stock from the Sydney CBD. Waste streams were measured separately for landfill, reuse and recycled materials. Descriptive and clustering statistics are presented and analysed. Findings From a total of 9,167 tonnes office fitouts demolished, 5,042 tonnes are going to landfill. The main contributor to landfill stream is the mixed waste generated in a fast-track demolition process. This approach partly resulted from the office interiors lacking regularity and easy disassembly. Moreover, considerable variability is observed in the waste per area, the waste streams and the waste compositions. Also, it is noteworthy that the recycled waste stream considerably increases when there exist economically viable conversion facilities, as for metals, hard fills and plasterboards. Research limitations/implications The research is focused upon work practices that take place in Australia; therefore, generalisability is limited to situations that have similar characteristics. Future studies are needed to verify and extend the findings of this research. Practical implications A key area arising from the research findings is the need to design fitout with recycling and reuse in mind to divert more from landfill. This must explore and incorporate onsite demolition processes to ensure the design is well suited to commercially dominant processes in the overall demolition process, as well as attention to developing economies of scale and viability in re-sale markets for reused items. Originality/value Little empirical or quantitative research exists in the area of office fitout waste. This research provides entry to this area via quantifiable data that enables comparison, benchmarking and diagnostic ability that can be used to underpin strategic solutions and measurement of improvements.

In Nanning basin, because of the peculiar relief and stratum model, the bearing support soil layers for pile foundation of high-rise buildings generally is gravel layer or mudstone layers or sandstone layers. On first or second terrace in basin, gravel layer is most chose as the bearing stratum for pile foundation of high-rise buildings. Static driven piles are commonly used in Nanning, because they have advantages of fast construction, high bearing capacity and noiseless despite costly. In this paper, the actual test data of a 32-stories apartment building of a college in Nanning has been consider- ed in detail. According to the present situation of project operations, the test results show that the piles which length is less than 6m can fully meet the design requirements. This project is a successful example.

Full textAbstract:
Purpose – The measurement of construction performance is a vexed problem. Despite much research effort, there remains little agreement over what to measure and how to measure it. The problem is made even more complicated by the desire to benchmark national industry performance against that of other countries. As clearly construction cost forms part of the analysis, the mere adjustment of cost data to an “international currency” has undermined past attempts to draw any meaningful conclusions. The paper aims to discuss these issues. Design/methodology/approach – This paper introduces a new method for comparing international construction efficiency, tested on a data set of 337 modern high-rise buildings in both Australia and the USA, and in so doing demonstrates that the ratio of cost over time is capable of ranking the efficiency of projects, building contractors, cities and even entire industries – not only today, but retrospectively over time. Findings – It is concluded that, based on data from the largest five cities in each country, efficiency on site is improving in both countries. The growth in baseline cost/m2 suggests a possible rise in project complexity over time. While the trend in efficiency improvement is similar, there is evidence that base costs in Australia have outstripped the USA, meaning that “real” construction efficiency in Australia is relatively less. If Australia held an advantage in the past, then it seems that advantage might be disappearing. The USA is outperforming Australia in terms of construction efficiency by 1.10 per cent per annum. Originality/value – Cost is measured as the number of standard “citiBLOC” baskets necessary to construct a project, where a standard basket comprises common and globally applicable construction items priced in each city in local currency, removing the need to apply currency exchange rates that otherwise introduce volatility and erroneous outcomes. Time is measured as the number of months between commencement on site and handover, inclusive of delays related to the construction process on site. Construction efficiency is defined as the ratio of construction cost per month, and is used to comment on the relative performance of the procurement process in different locations.

Full textAbstract:
The Building Act 2011 commenced in Western Australia on 2 April 2012. It introduced private certification for design and construction compliance, and reduced fees and timeframes for local governments to issue permits. This research project assessed the effect of the Act on the time and cost of building approvals in WA, using an internet-based, self-completion survey to obtain feedback from people on their experience of the new building approvals process. This research compared the cost of approval for 16 building projects under the new and old approvals processes. The research concluded that the new approvals process appears to be cost-neutral for the building industry as a whole. However, the cost of approval for the 11 building projects studied valued up to $1 million, particularly alterations to existing buildings, is an average of 4.0 times greater under the new approvals process.

Full textAbstract:
Purpose – This paper investigates the energy performance of aquatic centres in Victoria. Design/methodology/approach – Physical and occupancy characteristics and energy consumption from various centres were analysed to understand the interrelationship between numerous factors that contribute to the energy consumption of these facilities. Findings – The energy usage intensity of the facilities ranged from 632 to 2,247 kWh/m2 or 8 to 17 kWh/visit. Primary and secondary indicators were examined to find the key performance indicators. Research limitations/implications – This study sheds some light into the overall energy performance of aquatic centres in the temperate climate of Australia. More samples need to be collected to perform rigorous statistical analysis leading to a reliable benchmark model. System-wise investigation of energy consumption is required to determine where the energy is being used and the saving potentials of each system. Practical implications – This study has arisen from the need of managers of large aquatic and recreation facilities to benchmark the energy consumption of their own facilities. This study will fill the gap that currently exists in the area of energy rating systems for aquatic centres. Social implications – The results of this study showed that aquatic centres consume around seven times more energy than a commercial office building. Thus, if the energy consumption of aquatic centres could be reduced by as little as only 10 per cent, at least 3.5 million tonnes of carbon dioxide emission can be reduced. Originality/value – Environmental design standards for aquatic centres have generally been overlooked due to the complex nature of these buildings. As a result, this sector suffers from a general lack of both qualitative and quantitative information and benchmarking.

Full textAbstract:
Volumetric prefabricated building construction is growing in most developed countries; for example, in Sweden the market share of prefabricated building systems in the housing industry was more than 80%. However, in Australia only approximately 3–4% of new building constructions are prefabricated buildings in a year. A major hindrance to the growth of prefab construction in Australia is that systems are developed under commercial and confidential conditions. There are limited publicly-available research and case studies for certifiers, regulators, engineers and academia to provide independent information on the performance, advantages and disadvantages of prefabricated building systems. Independent designers and structural engineers are relying on the strength of the structural and non-structural element, as well as the connections of the prefabricated building systems. This strength is estimated from the “commercial-in-confidence” test of individual components by manufactures, and it might result in undesired outcomes in design. This paper provides an overview of available literature on structural performance, benefits, constraints and challenges of prefabricated building systems. This paper also highlights the research needed on the prefabricated building systems such as full-scale tests, numerical modelling, hybrid simulations, case studies and social and economic assessments. Being supported by sound academic research will increase the market demand for prefabricated building systems in Australia as well as in other countries.

Full textAbstract:
Amidst the inter-related challenges of climate change, resource scarcity, and population growth, the built environment must be designed in a way that recognises its role in shaping and being shaped by complex social and ecological systems. This includes avoiding the degradation of living systems in the design and construction of buildings and infrastructure, as well as enhancing the built environment’s resilience to disturbance by those systems. This paper explores the potential for biomimetic place-based design (BPD) to inform resilient and regenerative built environment outcomes by learning from local ecosystems. One recognised hurdle is the upfront resourcing required to establish the biomimetic knowledge base for each project. However, conducting BPD projects at-scale (i.e., city or region) can improve the method’s value-proposition by better leveraging upfront research efforts, design concepts, and strategies. This research identifies existing barriers to the widespread adoption of BPD and presents an action framework for capability-building across industry, government, and academia to enable application at-scale. Drawing on findings from workshops in the USA and Australia, it creates a resource for colleagues looking to apply BPD in a city or region and offers next steps for research and development.

INTRODUCTION In recent years, large high efficiency and Net-Zero Energy Buildings (NZEB) are becoming a reality that are setting construction and energy benchmarks for the industry. As part of this significant effort, in 2018, Mohawk College opened the 8,981 m2 (96,670 ft2) Joyce Centre for Partnership and Innovation (JCPI) building in Hamilton, Ontario; becoming Canada's largest NZEB and zero-carbon institutional facility. The building integrated a high-efficiency design, construction materials, and technologies; as well as renewable energy technologies to significantly reduce its annual energy consumption and greenhouse gas emissions. Furthermore, the JCPI building was also designed as a living lab where students, faculty, researchers and industry are able to monitor and validate the performance of this state-of-the-art facility. The building was designed to have an energy use intensity of 73 kWh/m2·year (0.26 GJ/m2·year); hence, potentially consuming approximately 80% less energy than the average educational service building in Ontario. This paper gives an overview of the design criteria and technologies that were considered to achieve this innovative building.

Full textAbstract:
Compared to traditional onsite steel construction, prefabricated industrial steel construction (PFISC) saves time, money, and resources. It results in sustainable steel structures that use fewer resources and are better for the environment. Despite their advantages, the private sector favors creating high-rise buildings in an old-fashioned way. In order to encourage the adaptability of prefabricated industrial steel buildings (PFISBs) in high-rise structures, this study critically evaluates the adaptable solutions offered in the literature on the recent developments, structural performances, present difficulties, and future potential. In mid-rise and low-rise structures, PFISC is frequently used. In research and case studies, PFISBs have proven to perform admirably under various adverse conditions, including in the event of an earthquake, wind, blast, impact, fire, collapse, and long-term sustained loads. The use of potential research solutions, the “Top-down” strategy, and the resolving of problems such as the structural-based design guidelines, column stability, discontinuous vertical and horizontal diaphragms, cluster columns and beams effect, damage-free and innovative inter- and intra-modular connections, high strength-to-weight modules, numerical simulation, and transportation will help PFISBs to become more widely accepted in high-rise structures. Compared to other materials, steel has recently demonstrated great promise for the construction of PFISBs. Additionally, China plans to increase their PFISC to 30% by 2026, Australia to 15% by 2025, and North America to over 5% by 2023, proving that it is a reasonable response to future urbanization concerns.

Full textAbstract:
Purpose Australia has a huge stock of community buildings built up over decades. Their replacements consume a large sum of money from country’s economy which has called for a strategy for their sustainable management. For this, a comprehensive decision-making structure is an utmost requirement. The purpose of this paper is to capture their sustainable management from four aspects, i.e. environmental, economic, social and functional. Design/methodology/approach The design process follows an extensive review of environmental and life cycle assessments and company context documents. Extracted factors are tailored to community buildings management following expert consultation. However, the resulted list of factors is extremely large, and “factor analysis” technique is used to group the factors. For this, an industry-wide questionnaire across Australian local councils is employed to solicit opinions of the list of factors. Findings The analysis has pinpointed 18 key parameters (criteria) to represent all four aspects. This paper presents the preliminary findings of the factors and the analysis results based on the questionnaire responses. Practical implications The final decision-making structure incorporates all these aspects and criteria. This can be used to develop a decision-making model which produces a sustainability index for building components. Asset managers can mainly use the sustainability index to prioritise their maintenance activities and eventually, to find out cost-optimisation options for them. Originality/value Most notably, this is the first study to apply all four sustainability aspects (environmental, economic, social and functional) to develop a decision-making structure for Australian community buildings’ sustainable management.

Full textAbstract:
IntroductionThe rapid increase in apartment construction in Australia has raised concerns about the impacts of poorly designed and located buildings on resident health and well-being. While apartment design policies exist, their content varies across jurisdictions and evidence on their impact on health and well-being is lacking. This cross-sectional observational study (2017–2021) aims to generate empirical evidence to guide policy decisions on apartment development and help to create healthy, equitable higher-density communities. Objectives include to benchmark the implementation of health-promoting apartment design requirements and to identify associations between requirements and resident health and well-being outcomes.Methods and analysisEligible buildings in three Australian cities with different apartment design guidelines will be stratified by area disadvantage and randomly selected (~n=99). Building architects, developers and local governments will be approached to provide endorsed development plans from which apartment and building design features will be extracted. Additional data collection includes a resident survey (~n=1000) to assess environmental stressors and health and well-being impacts and outcomes, and geographic information systems measures of the neighbourhood. The study has 85% power to detect a difference of 0.5 SD in the primary outcome of mental well-being (Warwick-Edinburgh Mental Well-being Scale) at a 5% level of significance. Analyses will compare policy compliance and health-promoting design features between cities and area disadvantage groups. Regression models will test whether higher policy compliance (overall and by design theme) is associated with better health and well-being, and the relative contribution of the neighbourhood context.Ethics and disseminationHuman Research Ethics Committees of RMIT University (CHEAN B 21146-10/17) and the University of Western Australia (RA/4/1/8735) approved the study protocol. In addition to academic publications, the collaboration will develop specific health-promoting indicators to embed into the monitoring of apartment design policy implementation and impact, and co-design research dissemination materials to facilitate uptake by decision makers.

Full textAbstract:
The fundamental goal of sustainable design for the built environment is to optimise the performance of buildings to minimise their impact on the environment. To achieve this goal, contemporary architects use a range of digital design environments, such as Computer-aided Design (CAD) or Building Information Modelling (BIM) tools. These allow architects to implement sustainable design principles and make optimal decisions about the ecological and energy properties of the building or environment being designed. Past research about architects’ uses of these tools for sustainable design have been focused on their capacity for optimising building performance and meeting architects’ design needs. In parallel, other studies have identified technological barriers and readiness factors for implementing sustainable design in several countries, including Australia. Researchers have suggested that presently, most architects are unlikely to perceive Building Performance Analysis (BPA) as their responsibility. It has also been found that the digital design tools need to more effectively support sustainable design. However, despite this body of past research, to date there is a lack of a more holistic understanding regarding architects’ perceptions about the alignment between sustainability practices and the capacity of digital design environments for supporting these, particularly in Australia. This paper addresses this knowledge gap, by presenting findings derived from semi-structured interviews with 18 professional architects in Australia, each with experiences in sustainable design and the use of digital design tools. The results are used to establish a conceptual model, which illustrates the relationships between a variety of factors affecting architects’ sustainable design practices. The findings suggest that in Australia, architects have more negative than positive experiences regarding their sustainable design practices, due to factors ranging from those related to the practice itself, to the digital design technologies and budget available for supporting their goals. This study also identifies an urgent need to enhance and better align the capabilities of digital design technologies with sustainable outcomes and associated organisational objectives, which the new model can assist in understanding and facilitating.

Full textAbstract:
Rammed earth/pisé is an earth building technique with a deep history in several countries across the globe. In the past twenty years, pisé buildings have seen a resurgence in popularity, primarily because of their environmentally friendly, passive energy characteristics, but also due to the aesthetic appeal of the fabric. As with all other earth architecture, pisé is susceptible to decay by moisture ingress. This paper presents longitudinal observations on the decay of capped and uncapped pisé walls of an early twenty-first-century complex of four buildings in Albury (NSW, Australia). It can be shown that while surface treatment with water-repellent sealants prevents the ingress of penetrating damp, it also traps moisture (falling damp) in the fabric by restricting evaporation. This leads to internal cleavage between the consolidated and the unconsolidated fabric and accelerates the decay of uncapped walls. The future design of both stabilized and unstabilized external rammed earth walls must ensure effective protection from rainfall through well-proportioned overhanging eaves. While the capping of feature walls may be aesthetically pleasing, and thus architecturally desirable, it does not adequately protect the walling against long-term decay.

Full textAbstract:
This paper traces the history of apartment design with an emphasis on spatial layout. It charts the events that have influenced apartment design in Sydney, Australia and provides a framework for understanding how changes in society, the economy, regulations, and architectural paradigms have influenced apartment layouts over time. Through a review of historical and contemporary apartment plan drawings in Sydney, we identify four chronologically distinct eras: layouts reflecting physically separate rooms and a healthier living condition (1900–1935); layouts following function (1935–1961); layouts enhancing interaction between family members (1961–2002); and layouts for independent life and to satisfy minimum regulatory requirements (2002–the present). We then consider these distinct eras in relation to political, economic, and social influences at the time. We propose that prior to 1961, changes in social paradigms and architectural thinking and the development of technologies were the main drivers of apartment layouts. After 1961, changes in the economy, the housing market, and regulations appear to have had more influence. This historical analysis provides insights into factors contributing to current apartment layouts and how different social, economic, and regulatory levers may influence them in future. These insights will be useful to both practitioners and academics in international jurisdictions considering how to encourage improved apartment spatial layouts in future.

Full textAbstract:
This study investigates the energy and cost performance of thirty recent buildings in Melbourne, Australia. Commonly, building design decisions are based on issues pertaining to construction cost, and consideration of energy performance is made only within the context of the initial project budget. Even where energy is elevated to more importance, operating energy is seen as the focus and embodied energy is nearly always ignored. For the first time, a large sample of buildings has been assembled and analyzed to improve the understanding of both energy and cost performance over their full life cycle, which formed the basis of a wider doctoral study into the inherent relationship between energy and cost. The aim of this paper is to report on typical values for embodied energy, operating energy, capital cost and operating cost per square metre for a range of building functional types investigated in this research. The conclusion is that energy and cost have quite different profiles across projects, and yet the mean GJ/m2 or cost/m2 have relatively low coefficients of variation and therefore may be useful as benchmarks of typical building performance.

Full textAbstract:
Purpose Crime and fear of crime in and around the university campus can affect enrolments and retention rates as well as compromising the safety, security and well-being of students and staff. The purpose of this paper is to explore user perceptions of personal safety using the “Prospect and Refuge Model” and crime prevention through environmental design (CPTED). Design/methodology/approach The study used a fear of crime survey of 88 students at a university in Western Australia. The respondents were asked to identify on a map, three locations perceived to be “safe” and three locations perceived to be “unsafe”. The six most commonly identified sites were then visually audited to measure the levels of “prospect” and “refuge” and CPTED features at each location. Findings The findings indicate the top three “fear spots” were associated with low levels of “prospect” and high levels of “refuge” – and generally, with poor opportunities for natural surveillance and CPTED qualities. The top three “safe spots” had consistently higher levels of “prospect” and lower levels of “refuge” in the site audits and responses to the surveys. Increased opportunities for surveillance were therefore associated with increased levels of personal safety. Research limitations/implications The survey is relatively small (88) and a larger study is certainly required to underpin these findings. The methodology is transferable to other universities and facilities seeking to manage crime and fear of crime. The research develops more finely nuanced measures for the concepts of prospect and refuge. Practical implications Interestingly, surveillance opportunities and perceptions of personal safety were perceived to be mediated by distance from buildings and by the construction of new buildings and infrastructure being carried out across the campus. This has implications for the construction of new universities and for those which are expanding. Recommendations are provided for new and existing universities and for those undergoing redevelopment. Social implications Improving students’ perception of personal safety can enhance their performance and retention at university. Originality/value No studies have investigated the campus design and layout and students’ perceptions of personal safety in Australia in this way. The approach is more “bottom-up” by first exploring users’ perceptions of “unsafe” locations, then assessing these sites in terms of the presence or absence of measures for CPTED and prospect-refuge.

Full textAbstract:
Architecture in Oxford between the Civil War and the early Georgian period presents a fascinating picture of great stylistic change and originality, as vernacular building traditions largely inherited from the Gothic of the Middle Ages were superseded by new design philosophies derived from Renaissance interpretations of classical architecture. The new architecture was driven by an increasingly élite and academic taste, largely dependent upon expensive foreign books and even more costly foreign travel, and necessitated fundamental changes to the established building practices of the colleges, which had hitherto relied largely on local master masons for both construction and design. As architecture ‘was something outside the ken of the average Oxford don’, knowledgeable men, especially those who had travelled abroad and seen modern buildings, became important arbiters of taste, and often drifted into architecture as a result. The first and most famous Oxford man to take this path was Christopher Wren of Wadham College in the 1660s, but he was followed a generation later by Henry Aldrich, Dean of Christ Church, after whose death in 1710 the mantle passed to George Clarke of All Souls College. It is with the significance of the latter two men’s activities at Christ Church that we will presently be concerned.

K. Reisonas was one of the most prominent creators of modern architecture of the 20th century during interwar period in Lithuania. He is the author and co-author of representative buildings in the cities of Lithuania, as well as in Riga and Adelaide (Australia). K. Reisonas graduated from Riga Real School (1913) and St. Petersburg Institute of Civil Engineers (1920). He has worked as the Engineer of the Šiauliai city and Head of the Construction Department of the Municipality (1922–1930), the Director of the Tenth1 Courses of Šiauliai Construction (1925), later – the Director of the Šiauliai Vocational School (1926), and an Advisor of Lithuania Chamber of Agriculture (1927–1928). Fourteen building to his design in Kaunas and Šiauliai cities are included in the list of cultural values of Lithuania. K. Reisonas’ early projects are characterized by historicism, eclectic elements, of «brick style». Later projects have the features of aesthetic rationalism, functionalism, and adaptation to urban and cultural-historical context. After the Second World War, he and his family immigrated to Germany, later Adelaide in Australia, where he participated in the life of the Adelaide Lithuanian community.

3D virtual management is a topic of growing interest. The AEC industry is undergoing a real revolution because of the technological changes that are taking place. Synchronized 3D visualization is one of the tools being deployed at an accelerated pace. This, together with collaborative work, contributes to optimal management for all stakeholders. The integration of geographic information systems and building information modeling and heritage BIM is one of the most innovative concepts; it enables the generation of collaborative, fluid systems. The objective of this research is to identify the most significant technological developments and potential applications of the aforementioned integration. For this purpose, after a bibliographic consultation (26,245 sources), two analyses are carried out (from the screening of 179 sources), one quantitative (bibliometric) and the other qualitative (focused on five key concepts). The results show that regarding the integration of GIS with BIM and HBIM, the highest concentration of contributions is in engineering with 30.66%, followed by computer science with 21.01%. The country with the highest number of citations is China with 717, followed by Australia and the USA with 549 and 513, respectively, but relativizing the number of citations based on various indices (human development index, gross national income per capita, and population-tertiary education level), Hong Kong (18.04), Australia (10.64), and Egypt (10.16) would take the top positions, respectively. Regarding universities, the entity that has generated the most references is Delft University of Technology (the Netherlands) with 15 papers, followed by University College London (UK) with 13. Finally, the results show that GIS and BIM and HBIM provide virtual 3D models with multiple applications for buildings and infrastructures.

Full textAbstract:
The current housing shortage problem in the country, especially among the low-income groups and the necessity to address their shelter needs, led to the introduction of Glass fibre reinforced gypsum (GFRG) panels in India. These panels were originally developed in Australia in 1990 and later introduced in India, China, Hong Kong and other countries. They are light-weight, load-bearing walls used for rapid construction of affordable and eco-friendly houses (individual units to multi-storeyed buildings) and are being used in India for more than a decade. These are prefabricated in controlled-conditions in factories, from gypsum plaster reinforced with glass fibres along with certain special additives and are available in a fixed size of 12 m length, 3 m height and 124 mm thickness. The panels are hollow, with cavities of size, 230 × 94 mm, aligned along the height. These panels can resist axial, in-plane and out-of-plane loads and various studies conducted worldwide established the suitability of the panel for the construction of walls, slabs, staircases and parapet walls. GFRG buildings consist of GFRG panels as walls and slabs (without any beams and columns) and can be constructed up to 5-8 storeys in low to moderate seismic zones, and lesser height in higher seismic zones. Thus to properly understand the structural behaviour of the GFRG building system and to develop a proper design guideline, comprehensive research works were undertaken in India and other countries which includes the study to determine the various material and structural properties of the panel and this paper presents a critical review of the experimental and theoretical investigations on the structural behaviour of GFRG wall panels.

Purpose – The purpose of this paper is to examine the development of vocational education for girls, focusing on how curriculum and pedagogy developed to accommodate changing expectations of the role of women in the workplace and the home in mid-twentieth century Australia. As well as describing how pedagogical changes were implemented through curriculum, it examines the way a modern approach to girls’ education was reflected in the built environment of the school site and through its interactions with its changing community. Design/methodology/approach – The paper takes a case study approach, focusing on the example of the J.H. Boyd Domestic College which functioned as a single-sex school for girls from 1932 until its closure in 1985. Oral history testimony, private archives, photographs and government school records provide the material from which an understanding of the school is reconstructed. Findings – This detailed examination of the history of J.H. Boyd Domestic College highlights the highly integrated nature of the school's environment with the surrounding community, which strengthened links between the girls and their community. It also demonstrates how important the school's buildings and facilities were to contemporary ideas about the teaching of girls in a vocational setting. Originality/value – This is the first history of J.H. Boyd Domestic College to examine the intersections of gendered, classed ideas about pedagogy with ideas about the appropriate built environment for the teaching of domestic science. The contextualized approach sheds new light on domestic science education in Victoria and the unusually high quality of the learning spaces available for girls’ education.

Healthcare constructions are public buildings that necessitate technical, healing and medical conditions, require common action from a number of disciplines and accommodate differing scales within themselves. Recently, these constructions have been a field of study whose momentum have continued to speed up for varying disciplines in terms of healing factors. This condition can be evaluated in terms of the basic requirement of “well-being†for each individual, the fact that the definition of health has become more comprehensive and the changes on spatial requirements in accord with developing technology. The definition by World Health Organization (WHO) will be distinctive for designers. WHO stated that “Health is not only protection from diseases and microbes but also a state of well-being physically, mentally and socially.†Furthermore, excitement, hope and other positive emotions that can be conveyed to human soul through design can be viewed as the basis of health philosophy constructed on the condition of “well-being†Even though the concept of health involves a comprehensive definition, its perception by users indicates change over time and it can be considered that this perception is far from a holistic approach in parallel with the definition of health. Healthcare constructions include places that have negative connotations in the conscious of the society. The design of modern healing places as livable spots, environments to where feelings of belonging can be attached and environments of relaxing and healing therapeutics has become a delayed requirement. This will only start with understanding the role of place on healing. Hospitals can be regarded as type of constructions that are convenient to healing reading. Therefore, the efforts to create theoretical background have been put forward in this study in order to evaluate the relation between healthcare constructions and perception of places to provide reading over hospitals. The study will mention hospital buildings in the historical process and changes on the healing perception of people. It is impossible to design the study independent of users in this healing reading from past to present. With the evaluation carried out in this respect, today’s spatial construction perception will be evaluated over The Royal Children’s Hospital, Melbourne, Australia and providing recommendations on construction design is targeted.
Keywords: Healing Places, Hospitals, Hospital design, Healing Design, Healthcare Constructions, Spatial Perception.

Full textAbstract:
Globally, buildings account for nearly 40% of the total primary energy consumption and are responsible for 20% of the total greenhouse gas emissions. Energy consumption in buildings is increasing with the increasing world population and improving standards of living. Current global warming conditions will inevitably impact building energy consumption. To address this issue, this report conducted a comprehensive study of the impact of climate change on residential building energy consumption. Using the methodology of morphing, the weather files were constructed based on the typical meteorological year (TMY) data and predicted data generated from eight typical global climate models (GCMs) for three representative concentration pathways (RCP2.6, RCP4.5, and RCP8.5) from 2020 to 2100. It was found that the most severe situation would occur in scenario RCP8.5, where the increase in temperature will reach 4.5 °C in eastern Australia from 2080–2099, which is 1 °C higher than that in other climate zones. With the construction of predicted weather files in 83 climate zones all across Australia, ten climate zones (cities)—ranging from heating-dominated to cooling-dominated regions—were selected as representative climate zones to illustrate the impact of climate change on heating and cooling energy consumption. The quantitative change in the energy requirements for space heating and cooling, along with the star rating, was simulated for two representative detached houses using the AccuRate software. It could be concluded that the RCP scenarios significantly affect the energy loads, which is consistent with changes in the ambient temperature. The heating load decreases for all climate zones, while the cooling load increases. Most regions in Australia will increase their energy consumption due to rising temperatures; however, the energy requirements of Adelaide and Perth would not change significantly, where the space heating and cooling loads are balanced due to decreasing heating and increasing cooling costs in most scenarios. The energy load in bigger houses will change more than that in smaller houses. Furthermore, Brisbane is the most sensitive region in terms of relative space energy changes, and Townsville appears to be the most sensitive area in terms of star rating change in this study. The impact of climate change on space building energy consumption in different climate zones should be considered in future design strategies due to the decades-long lifespans of Australian residential houses.

Full textAbstract:
There is significant scope for increasing the performance of commercial buildings across all dimensions of sustainability. For this to be realised, however, requires the development of more advanced real time assessment systems which provide automated eco-efficiency performance checking direct from 3D CAD as a regular and integral part of the design process rather than in late or post-design where options are more restricted. An integrated approach to directly link choice of materials and their environmental impacts with 3D CAD model object-oriented files containing significant building information, has been developed by the Cooperative Research Centre for Construction Innovation as a first step in this process. From 3D CAD objects, the system called LCADesign* automatically obtains the quantities of all building components associated with the selected products, calculates a complete inventory of constituents of building products, and links these to a Life Cycle Inventory database of building materials. The Life Cycle Inventory database includes all resource usage and emissions to the environment from the extraction of raw material resources, through their manufacture, transport, use, recycling, and maintenance. A number of performance assessment indicators can then be used to compare options in the choice of materials or design. An application to a commercial building project in Melbourne, Australia is provided to illustrate the potential of virtual building modelling.

Purpose This paper aims to explore traditional FM research and potential trends. Design/methodology/approach This was an exploratory review of literature. Findings The main thrust of the argument in this paper is that FM research develops a more communicable and proven understanding of how to apply a wide spectrum of externally developed methods in unique FM settings as well as developing new methods. Second, a more robust FM knowledge base can inform designers, engineers and architects given that FMs are experts of design in use. Research limitations/implications This research focused on the UK, Europe, America and Australia. It does not represent a comprehensive/systematic review of the research activities occurring in FM globally. Practical implications Research traditionally focuses on hard FM; in contrast, FM outcomes are heavily dependent on the way end users interact with and use organisational services and equipment. This suggests that there is a gap between practice and research, and that intuitive and in-depth FM knowledge about end users has yet to be captured and formalised through research. Social implications Development of FM research requires uptake of contemporary research trends towards partnered research, working across disciplines. Originality/value Achieving a more robust FM knowledge base would help capture the wealth of knowledge that FMs have about buildings in use; this could then be used by FMs and also by designers to improve their products and services in disciplines like engineering and architecture.

Full textAbstract:
Significant volumes of plantation hardwood are available in Australia to produce value-added engineered wood products such as cross-laminated timber (CLT). To validate the possibility of utilising this available resource, the bending structural properties of plantation Eucalyptus nitens solid board and finger-jointed feedstock were measured. The studied CLT panels produced from finger-jointed lamellas were subjected to bending strength, bending stiffness, rolling shear strength in bending, and pure rolling shear tests to obtain characteristic design values. Solid and finger-jointed timber test results suggested that boards used in longitudinal lamellas have a bending strength of 36.0 MPa and a modulus of elasticity (MOE) of 13,000 MPa. Finger-jointed timber in crossed lamellas presented a declared bending strength of 25.0 MPa. CLT panels showed a bending strength of 24.0 MPa and a rolling shear strength of 2.0 MPa. The experimental results for the CLT panels evidenced that the CLT bending stiffness matches up very well with the modelled results when an MOE of 13,000 MPa is used to describe the stiffness of longitudinal boards. The results presented in this study establish a basis for the commercial use of Australian plantation hardwood CLT in structural applications such as floors and roofs in commercial and residential buildings.

Full textAbstract:
Purpose – The purpose of this paper is to examine green building legislation requirements and practices in the construction project execution stage within the context of the South African construction industry. The rationale for this examination rests with the perception that the implementation of green practices (per se) has been recognised as being “behind” the legislation enacted to control the design and construction of green buildings. Design/methodology/approach – The research process consisted of a literature review to identify existing green building legislation and practices applicable to the project execution phase. This was supported by a sequential mixed-method research approach, which involved a survey of contracting companies based in the Western Cape Province of South Africa. Purposive sampling was used to undertake focused interviews with management staff and site operatives. Findings – Research findings established a number of issues, not least: a gap between green building practices and legislation requirements; a high degree of unawareness of green building legislation/practices by construction company stakeholders; selective implementation of health and safety legislative requirements; that management staff had a more “positive” attitude to green building practices than site-based staff who tended to be less motivated and open to such practices. Research limitations/implications – Results from this study are considered generalisable with the sample frame only. Research inference and projections should therefore only be made within this set, and not to the wider population of South African contractors (as this study was limited to the Western Cape Province). Practical implications – Implications from this research are applicable to construction company stakeholders within the population set. Practical considerations include the need to acknowledge a formal commitment to developing a sustainable built environment – especially cognisant of the gap between practices on site and green building legislation requirements. Moreover, this lack of awareness in respect of green building practices and legislation requirements impinges upon several wider areas, not least: construction company stakeholders’ positioning, health and safety practices; managerial and operational staff perceptions, and stakeholders’ willingness and motivation to proactively address these gaps. Social implications – Government bodies and allied professionals in charge of construction industry development are encouraged to consider the implementation of green building legislation requirements on construction sites. This reflection should encourage engagement through formative legislative provision and transparent awareness campaigns. Originality/value – This work is original insofar as it directly addresses the alignment of legislation to current practices within the context of the South African construction industry. However, similar exercises have been undertaken on green building legislation in other countries such as USA, UK and Australia.

Full textAbstract:
This study evaluates the technical, economic and environmental benefits of renewable energy resources (RER) for electricity supply to large size buildings in an educational institution. The cost of energy generation coupled with the epileptic power supply has led to the demand for an alternative source of energy supply to an education institution in Nigeria. The essence of renewable energy generation is becoming more glaring and a hybrid energy system (HES) is believed to deliver efficient and sustainable energy for the institutions; this paper aims to analyse the techno-economic assessment of a HES design setup at the College of Engineering, Afe Babalola University Ado-Ekiti for powering the university buildings; this grid connected system was assessed with various system configurations was simulated using hybrid optimization model for electric renewables (HOMER) software and the levelized cost of energy (LCOE) with the consideration of the HES benefits was developed. The results obtained from the simulation indicate that the grid and solar Photovoltaic (PV) system provide an optimal system that adequately meets the load demand with more renewable energy integration and this significantly reduces the cost of energy by 45% and also causes a 32.09% reduction in CO2 emissions; this configuration is environmentally sustainable and financially suitable for electrifying an educational institution.

Full textAbstract:
Purpose – This paper aims to investigate residential occupants’ motivations and behaviour on energy savings. Energy consumption in residential buildings is a major contributor to greenhouse gas emissions. Design/methodology/approach – By using an online survey questionnaire instrument, this research collected 504 sets of responses from households in the state of New South Wales, Australia. Findings – Through statistical analysis of the data collected, this research found that construction cost and government incentive were considered as the major influencing factors on achieving energy-efficient residential building development, and the lower bills resulted from the reduced energy and water consumption were considered as the most important benefits. The research also found that many households exhibited a high level of awareness and had implemented some sustainability improvement measures. It is suggested, based on these research findings, that governments should articulate, by means of education, the rationale and benefits of sustainable home development that are identified in this research and reduce material costs and increase government incentives. Originality/value – A framework on improving residential sustainability was proposed in this paper. Stakeholders in the sustainable home supply chain could use this framework as a reference to pave the way for energy efficient home development from their perspective

Full textAbstract:
Thin-walled steel hollow flange channel beams are commonly used as joists and bearers in various flooring systems in buildings. A new rivet fastened rectangular hollow flange channel beam was proposed using an intermittently rivet fastening process as an alternative to welded beams. This flexible fastening process allows rectangular hollow flange channel beams to have greater section optimisation, by configuring web and flange widths and thicknesses. In the industrial applications of rectangular hollow flange channel beams as flooring, roofing or modular building systems, their flanges will be fastened to supports, which will provide increased capacities. However, no research has been conducted to investigate the web crippling capacities of rectangular hollow flange channel beams with flanges fastened to supports under two-flange load cases. Therefore, an experimental study was conducted to investigate the web crippling behaviour and capacities of rectangular hollow flange channel beams based on the new American Iron and Steel Institute S909 standard test method. The web crippling capacities were compared with the predictions from the design equations in Australia/New Zealand Standard 4600 and American Iron and Steel Institute S100 to determine their accuracy in predicting the web crippling capacities of rectangular hollow flange channel beams. Test results showed that these design equations are considerably conservative for the end two-flange load case while being unconservative for the interior two-flange load case. New equations are proposed to determine the web crippling capacities of rectangular hollow flange channel beams with flanges fastened to supports. Test results showed that web crippling capacities increased by 78% and 65% on average for the end two-flange and interior two-flange load cases when flanges were fastened to supports. This article presents the details of this web crippling experimental study of rectangular hollow flange channel beam sections and the results.

Full textAbstract:
Purpose – This paper aims to explore shared use of space and facilities as a concept, and present and illustrate the use of a typology to help classify and describe the different options for sharing space and facilities within buildings for optimised use of a building portfolio. Design/methodology/approach – The content presented is based on a cross-sectional study with an inductive approach. The results are based partly on secondary data in the form of a literature review and a mapping of 20 examples from Europe, USA and Australia, and partly on primary data from observations and interviews with key actors from two cases in Denmark and an illustration case from Ireland. Findings – The typology classifies and describes four archetypes of sharing between different people, building owners and organisations, to be used when discussing, planning, establishing and evaluating new and existing shared spaces. Research limitations/implications – The typology is the result of a first exploration of shared use of facilities and does not claim to be fully comprehensive or final. Practical implications – The typology is intended for both researchers and practitioners, and aims at increasing the understanding of sharing as a way to minimise the need for building new by better utilisation of the existing building stock. Originality/value – Shared space and facilities is a relatively new topic with not much research undertaken. This typology provides a language for discussing shared spaces and a base for further developing the research field.

Full textAbstract:
PurposeAs the impacts of climate change become more evident, the need to adopt new ways of constructing buildings becomes more urgent. The Earth has experienced hotter climates globally for the last 70 years (NASA, 2019), and this has resulted in unprecedented levels of bushfire in Australia, flooding in the UK and drought in Africa in early 2020 (World Resources Institute, 2019). The predictions are for increased temperatures globally and increasing carbon emissions from fossil fuel consumption. There is a critical need to reduce the reliance on fossil fuels as a building energy source (WCED, 1987). Existing renewables focus on solar, wind and wave power, where technological improvements have increased efficiencies (Hinnells, 2008). Uptake of the technologies is variable depending on location and willingness to adopt renewables. As well as further uptake of existing renewable energy sources, we need to look wider and across traditional discipline groups, at new technologies such as biotechnologies. One potential energy source is biofuels. Biofuels are produced from biomass, which is algae. In 2016, the BIQ, a four-storey apartment building, was constructed in Hamburg, Germany. The BIQ features glazed façade panels filled with algae to produce biomass and solar thermal energy. Could algae building technology (ABT), in the form of façade panels, offer a new renewable energy source?Design/methodology/approachWhat are the technical issues associated with Algae building technology? This qualitative research sought to identify what technical issues likely to arise in terms of algae building construction, operation and maintenance. Semi-structured interviews with 24 experienced built environment professionals in Australia were undertaken in 2016 to assess the most likely issues that could arise with this new innovative technology.FindingsAs a result, a greater understanding of the range of technical issues related to design, construction, maintenance and operation were identified, as well as the perceived importance of those issues. It was possible to identify the top ten technical issues built environment professionals are concerned about with regard to ABT. The results can inform future designers of ABT.Research limitations/implicationsThis research was restricted to the views of 24 experienced built environment practitioners in Sydney, Australia. None of whom had direct experience of Algae Building Technology. Though knowledgeable, a greater number of interviews may have identified other technical issues.Practical implicationsNo guidelines exist for Algae Building Technology, and this research identifies a comprehensive range of technical issues that need to be considered for the technology to function at optimum levels. As such, this is a starting point for built environment professionals who may be asked to provide professional advice and guidance.Originality/valueTo date, no evaluation of Australian based built environment professionals has been conducted into the technical issues associated with Algae Building Technology.

Full textAbstract:
Purpose – This paper aims to investigate how unique features of built facilities would affect the application of greenhouse gas (GHG) emissions trading, and to explore what adaptive measures may be taken for emissions trading to be applied to the built environment. Emissions trading is a financial tool to encourage GHG emissions reduction in various industries. As the building sector is responsible for a large amount of GHG emissions, it is valuable to explore the application of emissions trading in built facilities. Design/methodology/approach – The analysis is based on a comparative study reviewing the current emissions trading schemes (ETSs) in Australia, Japan and the UK covering the building industry, and to evaluate the approaches adopted by the schemes to tackle the problems related to buildings and facilities management. Findings – The research findings reveal that the small energy savings of individual building units, the large variety of energy-saving technologies and the split incentives and diverse interests of building owners and tenants would be the barriers hindering the development of emissions trading. To overcome these barriers, an ETS should allow its participants to group individual energy savings, lower the complexity of monitoring and reporting approaches and allow owners and tenants to benefit from emissions trading. Originality/value – This article provides a comprehensive overview of the current emissions trading practices in the built environment. Besides, it raises the attention and consciousness of policymakers to the need that building characteristics and facilities management should be taken into consideration when designing an ETS for the building sector.
