Purpose The concept of adaptive reuse is an effective strategy for enhancing heritage assets, economic, cultural and social values. The purpose of this paper is to propose a method to reuse historic buildings within appropriate time frames. The adaptive reuse potential (ARP) model assesses the potential of buildings based on obsolescence criteria in order to determine the optimal time for changing the use of such assets. Design/methodology/approach Both quantitative and qualitative methods have been used in this research to evaluate the reuse potential of The Mashrooteh Building by using the ARP model. Predicting and evaluating the physical life, useful life and potential of the historic Mashrooteh building in Tabriz will ensure its reuse and will increase its future life. Findings Findings have shown that to increase the future life of The Mashrooteh Building, its adaptive reuse quality needs to be improved for the next intervention within a reasonable time. Further procedures can be outlined when the appropriate time for future rehabilitation is known. Originality/value With an emphasis on conservation of national heritage as well as promoting sustainable development, the overall future life of assets can be extended. The significance of this study is closely related to organizations dealing with the conservation and rehabilitation of historical buildings with the emphasis on sustainable improvement of environmental, economic, social and functional aspects in the best possible time frame. The result of this study will add a value to existing sustainable reuse database in Tabriz and other countries in the Middle East region.

A novel integrated mathematical model for the devaluation of residential buildings with time is presented. Devaluation model is an useful tool to predict residual life span of the building. Knowing how building behaves with time, one can influence on its properties by the means of renovation or reconstruction activities which counteract the aging processes. This approach can be regarded as the way to make total service life span of residential buildings longer.

Playthings are often engineered to replicate the character of real organisms. In the past, inventors lavished great expense on their lifelike automata, their constraints being typically related to the mechanical technology they employed and the amount of time and effort they were able to commit to the enterprise. The devices that are currently produced are usually intended for the mass market. The cost of production therefore is a major concern, even though the technology is more sophisticated and highly automated than in the past. Consequently, toymakers and engineers, as well as artists, of the past and present alike have had to think abstractly about living systems in order to construct their simulacra economically. This essay examines a number of lifelike toys to discover the properties of real organisms that their designers have attempted to recreate. That we, as users of these devices, so readily recognize in them a degree of lifelikeness demonstrates the extent to which intuition may sway our intellectual reasoning about real biology. As a result, an innovative toymaker or artist is able to manipulate us to zoomorphize even the most extreme abstractions—at least momentarily—despite our rational reluctance to accept the trickery.

Full textAbstract:
In recent years, much research has been conducted internationally to quantitatively evaluate the environmental impact of buildings in order to reduce greenhouse gas emissions and address associated environmental problems. With this in mind, the Green Standard for Energy and Environmental Design (G-SEED) in South Korea was revised in 2016. However, the various possible evaluation methods make it difficult to conduct building life cycle assessment. Moreover, compared to research on residential buildings, life cycle assessment research on non-residential buildings is scarce. Therefore, this study analyzes primary building materials for life cycle assessment of current non-residential buildings to support Korean G-SEED requirements. Design documents for various non-residential buildings are obtained, and the types and numbers of materials used in production are determined. Next, the primary building materials contributing high cumulative weight based on the ISO14040 series of standards are analyzed. We then review the most commonly-used building materials while considering non-residential building types and structures. In addition, construction material reliability is evaluated using the environmental impact unit value. With our results, by suggesting the primary building materials in non-residential buildings, efficient life cycle assessment of non-residential buildings is possible in terms of time and cost.

Abstract Buildings account for 40% of global Greenhouse gas (GHG) emissions. In heating-dominated climates, most building-related emissions originate from building stock operational energy, especially from buildings constructed before energy requirements were introduced. Renovation can mitigate operational emissions, however, materials should be included to increase the mitigation potential. Life-cycle assessment (LCA) includes emissions from materials and energy but are time-consuming in renovations because BIM-aided approaches for automating inventories are inaccessible for existing building fabric. This paper proposes a parametric inventory-generator for existing buildings, which defines material quantities through few key variables, which are accessible in early design stages, and which relate to a reference model for a specific building type. The generated model includes LCA inventory data such as service life, replacements, and End of Life from a generic impacts database. The model is adjustable and can be supplied with predefined renovation interventions and new components. The proposed simplification has potential to facilitate modelling of LCA inventories for every existing building, and makes LCA feasible for more than deep renovations, offering a base for the proposed renovation pass by the EU commission. Future research will add building types and explore implementing default inventories based on cadastre data as public resource.

Full textAbstract:
Sustainable development, which has become the priority study of architectural design, is receiving increasing attention with global climate change. At the same time, the building industry is urgently changing towards intelligent and digitalized tendencies. As a result, Building Information Modeling (BIM) and the Internet of Things (IoT) make crucial contributions to the transforming process. However, there is little knowledge of the integration of BIM–IoT in sustainable building from a macro perspective. Moreover, most existing research adopts a literature review method and lacks objective quantitative analysis. Few papers use bibliometric analysis to study the respective BIM and IoT research fields. Furthermore, few studies use Citespace software tools to analyze the integrated application of BIM–IoT. Therefore, this paper aims to investigate the research frontiers and knowledge structure in BIM–IoT integration and the relationship between BIM-IoT and sustainable building and explore the research hotspots, trends, and future research directions. A quick and objective method was proposed to understand the research status of these new and rapidly developing fields. This paper uses topic search in the web of science core collection to obtain relevant literature and then uses Citespace for bibliometric analysis based on the literature review. Controlled terms and subject terms statistics from the Engineering Index core database search results are also used to briefly examine the fields’ research frontiers and hotspots as obtained from Citespace. The results show that: (1) The research on BIM–IoT integration focuses on building intelligence with BIM as the basis of application, and research on BIM–IoT integration within the field of sustainable building is currently focused on the first three phases of the life cycle. (2) The development of sustainable buildings needs to be considered on its human and social dimensions. BIM provides a platform for sharing information and communication among stakeholders involved in the building’s entire life cycle. At the same time, IoT allows occupants to better participate in buildings’ sustainable design and decision making. (3) In the future, more emerging technologies such as cloud computing and big data are required to better promote sustainable buildings and thus realize the construction of sustainable smart cities. At the same time, researchers should also pay attention to the sustainable transformation of existing buildings.

Decision-making on whole-life-cycle net-zero-carbon buildings is critical for addressing carbon emission and environmental problems. However, there is a lack of a data integration framework and an open international standard approach integrating key decision variables to support scientific computations and decision-making for whole-life-cycle net-zero-carbon buildings. Building information modelling (BIM) is an open international standard representing building information. Digital Twin (DT) can capture and monitor real-time building conditions to facilitate building operation. Integrating information acquired by DT with BIM has considerable potential to enable an open international standard based computational representation of key decision variables throughout the whole-building life cycle process. This paper aims to develop a novel conceptual framework that integrates BIM and DT to support net-zero-carbon buildings. The framework is developed using an open international standard approach and the ontology-based representation method, to define key decision variables using entities, properties, and relationships, and integrates captured data via DT. The research makes significant contributions to enable net-zero-carbon buildings and paves the way for future research on an automated system to support decision-making for the whole-life-cycle net-zero-carbon buildings.

People that are my neighbours, acquaintances and with whom I shared my life as well. As so, I decided to present the pictures in a form of photo-board in order to put together shared experiences. This essay is not a study of daily life under quarantine, or how life is in a certain period of our time. It may be an effect, but not its reason. Rather, it attempts to portray life in a small-scale. Such small-scale is made up of daily routines and experiences of cleaning, talking, waiting as well as feelings of solidarity, solitude, fear and sometimes hope. It is the idea of shared experience that turns silence and waiting not as a singular experience, but a communal space, as is the daily life in a building

Sustainable building practices are rooted in the need for reliable information on the long-term performance of building materials; specifically, the expected service-life of building materials, components, and assemblies. This need is ever more evident given the anticipated effects of climate change on the built environment and the many governmental initiatives world-wide focused on ensuring that structures are not only resilient at their inception but also, can maintain their resilience over the long-term. The Government of Canada has funded an initiative now being completed at the National Research Council of Canada’s (NRC) Construction Research Centre on “Climate Resilience of Buildings and Core Public infrastructure”. The outcomes from this work will help permit integrating climate resilience of buildings into guides and codes for practitioners of building and infrastructure design. In this paper, the impacts of climate change on buildings are discussed and a review of studies on the durability of building envelope materials and elements is provided in consideration of the expected effects of climate change on the longevity and resilience of such products over time. Projected changes in key climate variables affecting the durability of building materials is presented such that specifications for the selection of products given climate change effects can be offered. Implications in regard to the maintainability of buildings when considering the potential effects of climate change on the durability of buildings and its components is also discussed.

This enables all phases and territories of the whole building life-cycle to achieve in-time information-sharing so as to overcome traditional territory management pattern. This also improves the running mode and information management during the phases of design, costing, construction and operation.

Abstract High-rise office buildings are naturally energy-intensive as energy is required in large quantities to run modern building services and to power equipment needed for a hitch-free operation of the buildings. It was found in studied literature that maintaining good indoor environmental quality through air-conditioning, lighting and powering of office equipment contribute the most to an office building’s total energy consumption. Hence, over time, various strategies have been employed to reduce the intense energy demand in high-rise office buildings. This paper adopted the use of both literature review and case study methods. The paper identifies the key energy efficiency strategies that have been successfully deployed in high-rise office buildings using the literature review approach. Also, case studies were conducted on three relatively new high-rise office buildings in Lagos, Nigeria by evaluating them against the background of the best practices in energy efficiency. The study found that deployment of energy efficiency strategies in high-rise office buildings in the study area is still very low especially in the areas of building orientation, building envelope design and the use of renewable energy. However, the use of day-lighting techniques and sustainable lighting systems are quite prominent in the office buildings studied. The study underscores the need to make high-rise office buildings more sustainable through energy efficiency strategies across the whole building life cycle of design, construction, use and end of life.

This study investigates the cumulative damage of a 20-story high-rise steel building equipped with buckling-restrained braces (BRB) under the likely occurrence of earthquake and wind events in the design life of the building. The objective of this research is to introduce a method for evaluating the cumulative damage of BRBs under multi-hazard events that are expected to occur during the service life of a high-rise building in order to achieve a safer building. A methodology is proposed using a Poisson point process to estimate the timeline of earthquake and wind events, wherein the events are assumed to be independent in nature. The 20-story high-rise steel building with BRBs is designed according to the Japanese standard and analyzed using the finite element approach, considering nonlinearities in the structural elements and BRBs. The building is analyzed consecutively using the timeline of earthquakes and winds, and the results are compared with those under individual earthquakes and winds. In addition to the responses of the frame such as the floor displacement and acceleration, the damage of BRBs in terms of the damage index, the energy absorption, the plastic strain energy, and the maximum and cumulative ductility factor are evaluated. It is observed that the BRB’s fatigue life under multi-hazard scenarios is a multi-criteria issue that requires more precise investigation. Moreover, the overall building’s performance and BRB’s cumulative damage induced by the sequence of events in the design life of the building is significantly larger than that under an individual event.

Abstract Buildings and construction have a significant effect on our natural environment and are major contributors towards global energy use and greenhouse gas emissions. Understanding and improving the environmental performance of buildings is critical to reducing these effects. While there has been some success reducing the operational effects of buildings, the significance of embodied environmental effects is rising. Built environment professionals must be better equipped to understand and integrate these considerations into iterative decision-making processes. Life cycle assessment (LCA) is a commonly used technique to quantify environmental effects across the life cycle of a building, however, it is not widely used by building designers. This is partially due to time constraints, the complexity of conducting detailed LCA, and the limited amount of building information available during early building design. The aim of this review is to identify the breadth of LCA tools available that support the building design process, with a focus on embodied environmental effects. A review of literature is conducted which identifies attributes and properties of these tools including: software attributes, relevance to design phases, features for building design, life cycle coverage, and data attributes. The review finds a lack of consistency between LCA tools, with varying levels of data transparency and completeness, and challenges for incorporating these tools into prevalent design workflows.

Building life cycle assessment is getting more and more attention within the topic of environmental impact caused by the built environment. Although more and more research focus on the embodied impact of buildings, the investigation of the operational energy use still needs attention. The majority of the building stock still does not comply with the nearly zero energy requirements. Also, in case of retrofitting, when most of the embodied impact is already spent on the existing structures (and so immutable), the importance of the operational energy rises. There are several methods to calculate the energy performance of buildings covering the range from simplified seasonal methods to detailed hourly energy simulations. Not only the accuracy of the calculations, but the computational time can be significantly different within the methods. The latter is especially important in case of optimization, when there is limited time to perform one calculation. Our research shows that the use of different calculation techniques can lead to different optima for environmental impacts in case of retrofitting. In this paper we compare these calculation methods with focus on computational time, accuracy and applicability to environmental optimization of buildings. We present the results in a case study of the retrofitting of a middle-sized apartment house in Hungary.

The integrated description of the building geometry and the element attributes of the building information model (BIM) can reduce the effort needed to acquire data for life cycle assessment (LCA) and life cycle costing (LCC) at each design stage while supporting their potential for analyzing life cycle performances and feeding back to the design process. To support this, several methods and tools have been proposed that aim to obtain the life cycle performances of buildings following the level of model fidelity with the life cycle inventory (LCI) database at different scales. However, inconsistencies in decision-making caused by regional differences in LCA/LCC data sources, benchmarks, and building standards cannot be ignored. In this study, a scalable LCA/LCC method integrated with the BIM platform is proposed for the whole green building design process in the Chinese context, and it is implemented with a developed tool based on Revit. A national-/regional-specified database of building elements and materials is established. Referring to China’s carbon-neutral target and relevant standards for green buildings, the baseline values are deduced, and a reference building is defined accordingly to facilitate the evaluation and improvement of the design scheme. According to the Assessment Standard for Green Building (GB50378-2019) and the survey of architectural design practices in China, the key parameters at different design stages are defined. The method and tool are demonstrated using the case study of a school building, analyzing its life cycle carbon emissions and life cycle costs throughout the design process. The results show that the proposed method can facilitate the improvement of the scheme at different design stages and that it can cope with different data accuracies and different LODs in the building information model in the Chinese green building design process. Lastly, the uncertainties raised by the data quality and time-associated factors are discussed.

The Christchurch earthquakes have highlighted the mismatch in expectations between the engineering profession and society regarding the seismic performance of buildings. While most modern buildings performed as expected, many buildings have been, or are to be, demolished. The ownership, occupancy, and societal costs of only targeting life-safety as the accepted performance standard for building design are now apparent in New Zealand.
While the structural system has a significant effect on the seismic performance of the entire building, including the contents, it is only about 20% of the total building cost. Hence, structural engineers should view the seismic performance in a wider context, looking at all the systems of the building rather than just the damage to structural items and life-safety.
The next generation of performance-based seismic design procedures, outlined in the FEMA P-58 document, provide engineers with the tools to express the seismic performance of the entire building in terms of the future life loss, facility repair cost and repair time. This paper will outline the FEMA P-58 procedure and present the results of a comparative study of six different structural systems for a three storey commercial and laboratory building: moment frame; buckling restrained braced frame; viscously damped moment frame; Pres-Lam timber coupled-walls; cast-in-place reinforced concrete shear wall; and base isolated braced frame. Each system was analysed as a fully non-linear structure and the calculated drifts and floor accelerations were input into the FEMA P-58 PACT tool to evaluate the overall building performance. The PACT tool performs loss calculations for the expected casualties, repair cost, and repair time from which a QuakeStar or SEAONC rating for the building can be obtained.

Abstract The role of design in transitioning towards a circular economy (CE) is strategic in the building construction industry as the potential for creating, developing, and sustaining circular value throughout the whole building life cycle is largely determined by the building design. Circular building design approaches that are being commonly deployed are often based on technical perspectives that assume buildings to be static products of the building construction industry. However, buildings are complex and dynamic with components and materials having their own individual life cycles, interacting dynamically with each other over space and time in a continual state of change. Moreover, changing stakeholder needs and expectations and other external factors add further layers of complexity in developing and sustaining the circular value created by the initial building design. Therefore, a holistic approach that accounts for the above contributors and integrates the building dynamism across its life cycle including stakeholder involvement, was ideated, based on the extant literature gap and the industrial need. The study conceptualised a holistic ‘design for circularity’ (DfC) framework based on a comprehensive literature review. The literature review was followed by 07 preliminary semi-structured interviews of relevant experts, so as to address relevant industry needs in developing this framework further. The findings enable the formulation of an overarching design centred framework to not only create, but also to develop and sustain circular value throughout the whole building life cycle, as presented in this paper.

Abstract—Nowadays Building Information Modeling, known as BIM has become a common topic in construction technology. Indonesian government has even accelerated the implementation of BIM as a requirement in planning above 2000 m2 since year 2018. The word renovation in BIM life cycle means one of the post-project building phases after maintenance, rehabilitation but before reach demolition phases as an ending of the building. On the other hand, renovation is not a strange thing for the Indonesian people and has direct meaning to its activity. Even though occupying a new property, there is always a tendency to change, add or even reduce some parts of existing buildings. Renovation is also unavoidable when there is a change in function in a building and it can be classified as adaptive reuse as part of the concept of sustainable building, a preservation and rehabilitation of an old building that has unique design or contains certain historical significance. This research is structured and focuses more on the issue of time efficiency which is very significant in the renovation stage. The method used in the form of a comparison between conventional methods with methods that apply the BIM concept. This is interesting to be observed as the benefits of research so that the concept of BIM can be understood and seen its real advantages.Keywords—building information modeling, renovation, efficiency

Structural systems that do not use a beam as the main component were first developed by Turner in 1906. This structural system is better known as a flat slab. The flat slab structure is supported by column heads and drop panels, or without drop panels, or without column heads. Several building codes such as IS 456: 2000, ACI 318-08, ACI 318-19, EC 2:2004, and NZS 3101 (Part 1):2006 provide guidance for designing flat slab systems under gravity loads only. However, many flat slab buildings are also built in areas with high earthquakes which can cause the collapse of buildings due to earthquake loads. In this paper the 10-level flat slab building structure design results are analyzed using nonlinear time history response analysis with the help of OpenSees Navigator software using several earthquake records, namely Kobe (Japan, 1995), Imperial Valley (California, 1979) and Tabas (Iran, 1978) which has been adjusted to the design spectra of the city of Yogyakarta. From the results of the analysis using OpenSees Navigator, it was found that the story drift that occurred was still within the limits required in the regulations, so that the building being reviewed was still within the limits of life safety design.

Due to the current environmental situation, the reducing of greenhouse gas emission and the saving energy is the phenomenon. The building sector is still growing and more and more energy is needed. Thermal performance of building envelope has been of great importance in the context of existing global warming issues. Buildings are responsible for 40% of energy consumption and 36% of Carbon Dioxide (CO2) emissions in the member states of the European Union. According to the research project Heartland Green Sheets, the recommended criteria for assessments of sustainable buildings materials are low embodied energy, recyclable, use renewable resources, locally or regionally produced, energy efficient, low environmental impact, durable, minimize waste, positive social impact and affordable. The contribution focuses on life-cycle assessment (LCA) and sustainability assessment of commonly used wall systems. The multi-criteria analysis of the contemporary wall systems in term of sustainable development is presented in the paper. The contemporary commonly used wall systems are assessed in terms of labour, time and financial demands, energy and environmental performance.

Full textAbstract:
Many super tall buildings are built up in China in recent years. The concept of low carbon based design has aroused much focus nowadays. There are few researches that combine structural design of super tall buildings with life cycle based low carbon design. Due to its huge quantity material and energy assumption, the super tall buildings exert great impact on the environment. In this study, an innovative new life cycle model is proposed for assess and optimize the life cycle environmental cost of super tall buildings, in which the space distribution of the building materials is considered besides the time dimension. A benchmark super tall building is established in this study to illustrate the application of the proposed new life cycle model. According to the case study results, a conclusion is drawn that a remarkable difference would be made in carbon emissions if low carbon based structural design method could be applied.

Ecological payback time was calculated for demolishing an existing commercial building with average energy performance and replacing it with an energy-efficient, prefabricated building. A life-cycle assessment was performed for a 5,000 ft2commercial building designed by Project Frog and prefabricated in San Francisco, California, and compared to the impacts of annual energy consumption and continued status quo operation of a comparable average commercial building. Scenarios were run both with and without rooftop solar panels intended to make the prefabricated building net zero energy. The analysis considers the materials and manufacturing, transportation, annual energy use of the new building, and disposal of the existing building, compared to continued annual energy use of the existing building. The carbon payback of a new building with no solar against operation of an existing commercial building was found to be roughly eleven years, and a building with enough rooftop solar to be net zero energy was roughly 6.5 years. The full EcoIndicator99 environmental impact payback for a new efficient building with no solar was found to be twenty years, and a solar net-zero building was roughly eleven years against operation of an existing commercial building.

Abstract The building industry has mainly focused on improving operational energy consumption to minimise the environmental impacts of buildings which are major sources of greenhouse gas emissions (GHG). However, considering the full life cycle of buildings, energy use and GHG emissions occur for reasons that extend beyond the operational phase and involve the embodied impacts of construction and disassembly. Circular building design can provide a holistic approach where the building’s whole life cycle is considered in a manner consistent with circular economy principles, minimizing global material consumption, reducing waste and insuring a more circular building material stock. To date, research on the wide-scale adoption of circular design and construction strategies in public projects is still lacking. On this basis, the case study of the new Joseph Bracops hospital in Brussels shows that circular building design principles can be applied in the healthcare sector within the framework of a public tender. The project integrates circular economy principles at different scales (city, site, building, element), optimises different material and energy flows and takes into account different timespans (short and long term). The study also offers insight and guidance for future research into how the urban hospital of tomorrow will be a resilient public venue. Such a venue can enable a more comprehensive approach of health promotion, reflected by the qualitative integration of circular economy principles both with a social and technical focus, connected to the community and capable to mutate over time.

Full textAbstract:
BIM is a concept and also a method currently applied throughout the world in the modern building construction. The impact and benefits of the BIM method are clear across all stages of the life cycle of buildings (project, realization, operation, demolition). The longest and most expensive phase of buildings life is the operation and usage part. Many common aspects and linkage of processes between the BIM method and the facility management, i.e. a modern asset management method, can provide greater efficiency for these activities, help reduce the cost of required building operations and maintenance and save time for individual activities. The BIM can be understood as an information management of buildings. Many common elements can create a synergy of processes related to the management of buildings. The article discusses these aspects and emphasizes the listing of the basic data and processes that are necessary for mutual interconnectedness.

Full textAbstract:
The building performance simulation (BPS) based on physical models is a popular method to estimate the expected energy-savings of energy-efficient building retrofitting. However, many buildings, especially the older building constructed several decades ago, do not have full access to complete information for a BPS method. Incomplete information generally comes from the information that is missing, such as the U-value of part building components, due to incomplete documentation or component deterioration over time. It also comes from the case-specific incomplete information due to different documentation systems. Motivated by the available big data of real-life building performance datasets (BPDs), a data-driven approach is proposed to support the decision-making of building retrofitting selections under incomplete information conditions. The data-driven approach constructed a Performance Modelling with Data Imputation (PMDI) with integrated backpropagation neural networks, fuzzy C-means clustering, principal component analysis, and trimmed scores regression. An empirical study was conducted on real-life buildings in Sweden, and the results validated that the PMDI method can model the performance ranges of energy-efficient retrofitting for family house buildings with more than 90% confidence. For a target building in Stockholm, the suggested retrofitting measure is expected to save energy by 12,017~17,292 KWh/year.

Abstract This project focuses on the dynamic modelling of two buildings: a school and a public building, both located in the Basilicata and Puglia regions. In order to define the passive energy requirement of the building and propose some energy efficiency solutions, an energy diagnosis was conducted in dynamic settings on these structures. The EnergyPlus™ calculation code is the method utilized for energy diagnosis in the dynamic regime. The dynamic technique enables simulation of real-world building circumstances and plant design based on real-world requirements and building management. Both buildings have significant historical significance, therefore improving their energy efficiency must take this into account. In the design of energy efficiency solutions, the enclosure’s properties are critical. It is the primary source of heat loss and sunlight gain, and it has an impact on indoor comfort. It is vital to consider often contradicting features of the building’s casing, such as heating, cooling, and natural and artificial lighting, when designing the building’s casing. For example, large levels of natural light must be allowed without excessive solar gains during the summer while still ensuring an acceptable quantity of solar earnings during the winter to reduce heating loads. As a result, the efficient configuration can’t just look at one element at a time; it has to look at all of them at the same time, taking into account all of the interactions between the many sources of energy usage. Thermo-hygrometric comfort is another factor to consider when it comes to protecting the human condition. The goal of integrated design for a long-term major redevelopment is to establish the best balance between energy efficiency and environmental burdens, not just during the operational period, but throughout the life cycle. During the redesign process, resources such as life cycle analysis (LCA - Life Cycle Assessment) can be used to objectively quantify the possible environmental implications of new materials, systems, and energy flows (from their supply up to future disposal scenarios at the end of life). Furthermore, by comparing several project options, it is possible to identify which, with the same energy efficiency, causes the least environmental damage. Economic and social sustainability analyses can also be combined. Modern building relief techniques (geometric, material, and thermal) were applied in this study for energy diagnosis and LCA analysis to determine the optimal design options for environmental impacts. The thermal power plants that the solution proposes are completely integrated within the buildings in which they will be put and manage to ensure a perfect mix of energy savings, economic savings, and environmental sustainability.

Full textAbstract:
Worldwide authorities are increasingly concerned about construction’s efficiency and sustainability, leading to the development of high-performance buildings. However, such facts have shifted a significant percentage of the building life cycle environmental impacts from the operation to the product and construction phases. Thus, the need to evaluate and select more sustainable materials and construction solutions arises, to also minimize impacts from these stages. To evaluate those impacts, LCA and LCC analysis are usually applied to assess the building impacts and costs, through the different life cycle stages. Despite the usefulness of LCA and LCC methods during the project phase, they are usually evaluated in the project later stages. It is too complex and time-consuming to gather and process all the required data during the project early stages. With the recent deployment of BIM, the opportunity to automate and shift LCA and LCC analysis to project early stages stands out. Facing the research gap, this study aims to develop a BIM-based decision-making tool for designers to evaluate the environmental, economic, and functional performance of different building construction solutions. To do so, 18 different simulation scenarios have been created in Autodesk Revit with different combinations of external walls, roofs, and floors. Then, a framework was developed in Dynamo to automatically characterize the building elements life cycle environmental impacts and costs, as well as to automate the LCA and LCC analysis during the project early stages. The outcomes can significantly reduce the required time, errors and efforts when performing LCA and LCC analysis, providing designers with real time decision support data and making an important contribution to the use of BIM for sustainability purposes.

<p>Concrete durability is the ability of concrete to last as it was originally planned, in the structure of a building can be defined as the ability to maintain function, stability and aesthetics due to environmental influences so as not to incur large maintenance and repair costs during the planned service life. The durability aspect is very important, especially for infrastructure that has a fairly long service life. Building life is the period or time during which a structure is required to continue to function as planned. In building structures whose construction has been completed, both new and old buildings, specific data related to the quality of the concrete and the planned age of the building is quite difficult to obtain, this is because the influence during the implementation of construction is also not good in governance. documentation, both technical documents and other non-technical documents, therefore it is necessary to have a sufficiently representative tool to test the concrete quality of a building that has been completed to comply with the quality of the built concrete.</p>

The book, focusing on youth–adult partnerships for the purpose of social change, explores a set of field-expanding questions such as, “What do youth–adult partnerships look like in practice?” and “What are the relational and organizational practices that enable youth–adult partnerships to exist?” In addition to youth workers and youth development organizations, other groups of adults would benefit from reading the chapters’ rich exploration of dilemmas and strategies, such as funders, K-12 educators, and evaluators. Ultimately, this book honors young people and youth workers as important actors in social change and elevates the importance of their joint efforts. The deep relationship between youth work and a strong democracy clearly emerges, challenging us all to be “at our best.”

Abstract Technological progress is reflected in all industries. Obsolete project manuals in the construction industry are being replaced by digitized automated controls that monitor the project in real-time. One of the main trends is the introduction of technologies based on data analytics. Effective use of technology to collect and analyse data is key to improving a building's planning and management across its life cycle. Building information models, which process digital content related to the entire life cycle of a building, are becoming an effective tool. The main goal of the paper is to design and identify the structure of the developed database, which, based on the acquired knowledge, contains graphical models that have selected non-graphical information.

Purpose – The purpose of the Building Everyday Life programme is to improve parenting outcomes through better sharing of family responsibilities and to encourage a strong sense of solidarity and community. Design/methodology/approach – Data have been obtained from the pre-test and post-test applications, respectively, using two instruments: the Inventory of Parenting and Family Life Patterns and Resources, and the Final Evaluation Questionnaire for parents. The authors also use these tools to evaluate the degree to which the changes are maintained six months after the completion of the programme. Participants in the study comprised a group of 35 individuals that included parents in nuclear families and single mothers. The assessment process involved three stages: a pre-test assessment, a qualitative report (summative assessment) and, finally, a post-test assessment at least six months after completion of the programme. Findings – The results show lasting changes over time. Regarding domestic work, parents say that they are more aware of the need to achieve a fairer and more equal distribution of the tasks in question. Families also report that they have perceived changes in the dimensions of communication and conflict resolution. Bearing in mind the limited nature of the aforementioned changes, the results suggest the need for support processes over time, as well as the establishment of follow-up sessions with families. Originality/value – The main contribution of the study is to show that the Building Everyday Life programme is effective and valuable in improving parental educational styles.

The archaeological context of a recently unearthed sundial from the Egyptian Valley of the Kings suggests that the object was used to define the work hours of labourers engaged in building tombs. An analysis of the sundial enables us to establish its precision and the scientific rationale on which the measurement of time is based. This allows us to gain insights into the role of astronomical time in Egypt c. 1200 BC. Administrative texts of the same period found nearby offer additional evidence on the everyday life of the workmen and the importance of social time in regulating their activities. This provides us with a unique opportunity to compare astronomical with social time and ponder the arising implications from the convergence or divergence of the two.

ABSTRACT A dynamic approach to mandatory building standards is a principle-based approach. This approach complements rule-based standards for buildings and takes into consideration the principles behind building regulatory reform such as sustainability, building life-cycle and their social and economic co-benefits. This paper highlights how a principle-based approach can potentially address the engagement mechanisms with building stakeholders in one performance scheme. Instead of setting a one-time high-performance building target, principle-based targets are consecutively set by Principle-based Responsive Regulation that encourages adaptation through public policy consultations, incentives and disincentives, as well as enforcement mechanisms, working in unison to lower building-sector carbon emissions. This can be encouraged and enforced through responsive pyramids, giving stakeholders of the sector flexibility in selecting adaptation strategies to meet building performance targets. The discussions in this paper are limited to examining the potential application of principle-based responsive regulation approaches to the building sector.

Full textAbstract:
In the current study, a simplified seismic life cycle cost (LCC) estimation procedure is proposed utilizing the mean values of the structure’s main input variables. The main input variables of the building are used for constructing a relationship between the structural fundamental period (T) and an average estimation of the LCC (LCCavg). Using the actual building properties related to damage probability, the T–LCCavg relationship is used to obtain the final LCC (LCCfin). The equivalent single degree of freedom (ESDOF) model and SAC-FEMA framework are utilized for damage probability calculation. The dispersion measure in demand is approximately calculated based on the mean plus one standard deviation of the seismic hazard response spectrum, and, then, verified through nonlinear time history (NLTH) analyses of the original structure. Five and three-story steel buildings are used as case studies for verification of the proposed method. The analysis results indicate that the proposed procedure provides reasonable LCC estimations for low-rise buildings dominated by the fundamental mode of vibration.

Full textAbstract:
Establishing an effective long-term maintenance plan is essential to ensure the sustainability of a building. Among the various components of a building, the mechanical, electrical, and plumbing (MEP) components are complexly affected by various parameters, such as quality and user pattern, with respect to the service life. Besides, these components are replaced at different points in time, which becomes one of the main risks when establishing a maintenance plan for the building. Therefore, it is very important to consider the uncertainty in calculating the service lives of MEP components in a systematic and reasonable way. This study aims to systemize the MEP components of residential buildings and analyze their service life patterns using a probabilistic approach for long-term maintenance planning. The analysis was performed on 54,318 maintenance cases from 1998 to 2017 at 65 twenty-five-year-old rental apartment buildings in South Korea. Before performing the analysis, a service life matrix was established by classifying the MEP components into 12 types and setting the service life time at 6–25 years. Then, the service life distribution was derived for each MEP component. The probabilistic approach can provide information for rational maintenance decision-making regarding each MEP component as well as basic service life settings. Since the performance of the MEP components deteriorates due to various reasons, de facto uncertainty exists in the service life of each component; thus, the probabilistic approach can serve as an important decision-making method. If probabilistic methods are developed by acquiring the cost data in addition to the frequency of maintenance activity used in this study, a more effective long-term maintenance plan can be established.

This paper presents a life cycle assessment (LCA) study that examines a number of scenarios that complement the primary use phase of electric vehicle (EV) batteries with a secondary application in smart buildings in Spain, as a means of extending their useful life under less demanding conditions, when they no longer meet the requirements for automotive purposes. Specifically, it considers a lithium iron phosphate (LFP) battery to analyze four second life application scenarios by combining the following cases: (i) either reuse of the EV battery or manufacturing of a new battery as energy storage unit in the building; and (ii) either use of the Spanish electricity mix or energy supply by solar photovoltaic (PV) panels. Based on the Eco-indicator 99 and IPCC 2007 GWP 20a methods, the evaluation of the scenario results shows that there is significant environmental benefit from reusing the existing EV battery in the secondary application instead of manufacturing a new battery to be used for the same purpose and time frame. Moreover, the findings of this work exemplify the dependence of the results on the energy source in the smart building application, and thus highlight the importance of PVs on the reduction of the environmental impact.

The use of Building information modelling for the design and construction phase of a building has been thoroughly looked into by researchers and practitioners and there is evidence to support that it is beneficial for reducing cost, time and improving communication. Yet the potential use of BIM for the operational and management phase (Facilities management), besides maintenance schedules and equipment information and location, is still not clearly identified. The UK Government, institutional clients and major private owners are now demanding for BIM for new construction and major refurbishment but given that 70-75% of the current UK building stock will still be in use in 2050, a significant part of the existing facilities will not have an information model till the next major refurbishment, creating a major gap in the built environment. This paper presents a new framework aimed at creating information models for facilities management requiring minimal BIM skills and discusses the impact that models created for the operational stage would have on the whole life cycle of a building.

Energy efficiency of existing buildings is a concept to manage and restrain the growth in energy consumption and one of the crucial issues due to the magnitude of the sector. Educational buildings are in charge of about 15% of the total energy consumption of the non-residential building sector. However, not only operational but also embodied energy of a building should be reduced to get the overall benefits of energy efficiency, where, using energy efficient architectural measures and low emitting materials during every retrofit action can be a logical step. The majority of buildings in Turkey and EU was built earlier than the development of the energy efficiency in the construction sector, hence, without energy retrofit, consume an enormous amount of energy that can be averted significantly by the implementation of some even not advanced retrofit measures. Furthermore, demolishing of a building to construct a new one is not a rational approach concerning cost, time and environmental pollution. The study has been focused on the impact assessment of the various architectural scenarios of energy efficiency upgrading on the Life Cycle Energy Consumption (LCEC) and Life Cycle CO2 (LCCO2) emission. Within the scope of the study, a primary school building is selected to be analysed. Through analysis, the total embodied and operational energy use and CO2 emission regarding the life cycle phase of the building is quantitatively defined and investigated in the framework of life cycle inventory. The paper concentrates on the operation and embodied energy consumption arising from the application of a variety of measures on the building envelope. An educational building with low LCCO2 emissions and LCEC in Turkey is proposed. To exemplify the approach, contributions are applied to a case study in Istanbul as a representative school building. The primary energy consumption of the case study building is calculated with a dynamic simulation tool, EnergyPlus. Afterwards, a sort of architectural energy efficient measures is implemented in the envelope while the lighting and mechanical systems remain constant. The energy used in the production and transportation of materials, which are the significant parts of the embodied energy, are taken into account as well.

Electromagnetic force (Sunlight) interacts with inorganic chemistry available to us given out by the stars in the universe plausibly triggers the formation of extra-terrestrial biological molecules of proto cells under abiotic conditions, as evidenced by their presence in meteorites.' Proto cells’ might theoretically give rise to living organisms with a manifested soul, allowing 'Ribose' to be formed from ice grains hit by sunlight for RNA and DNA at the same time. The presence of life's building blocks and other important organic chemicals like ribose in meteorites, including some microscopic life forms that aren't native to Earth, may have led to the 'Panspermia Origin of Life' and the 'Evolution of Life on Earth' which is evidenced by the definition of 'Meteorites' in Vedic Scriptures, such as the "Bhagavad Gita" (3000 BC) and "Brihat Samhita" (520 AD) that they are the souls of righteous people who have returned to earth to be reborn.

Full textAbstract:
The article analyzes modern methods for monitoring the technical operation of buildings and structures. Technical inspection of buildings and structures is a separate type of construction activity. The necessity for a technical survey is caused by the physical and moral deterioration of building structures and changes of terms of use, as well as the absence in building codes of an explicit account of the time factor. Ensuring the operability of structures at a specific moment of existence requires a set of measures that differ from the design, manufacture and installation of building elements associated with the creation of normal conditions for the life of enterprises in industrial buildings and structures and, above all, the safety of the operation process.
Specialists in the technical operation of buildings and structures have new tools for more accurate determination of defects and supervision of buildings and structures. The emergence and development of IT technologies, in particular, the use of mathematical, computer modeling techniques have demonstrated unprecedented opportunities for a comprehensive approach to testing the performance of buildings. Most modern methods of technical inspection of buildings do not require significant financial and labor costs; they can be directly implemented both during the planning of the facility and during its operation without reducing the bearing capacity of structures, unlike classical methods (visual, visual-instrumental, etc.). Their goal is to control the technical condition of building structures and early diagnosis of threats to the existence of the object. The integrated use of these methods at different stages of the life cycle of buildings will increase their service life and the comfort and safety of staying in them.

Older people living in residential and nursing care homes spend a large proportion of their time within the boundaries of the home, and may depend on the environment to compensate for their physical or cognitive frailties. Regulations and guidelines on the design of care buildings have accumulated over time with little knowledge of their impact on the quality of life of building users. The Design in Caring Environments Study (DICE) collected cross-sectional data on building design and quality of life in 38 care homes in and near Sheffield, Yorkshire. Quality of life was assessed using methods which included all residents regardless of their frailty, and staff morale was also assessed. The physical environment was measured on 11 user-related domains using a new tool, the Sheffield Care Environment Assessment Matrix (SCEAM). Significant positive associations were found between several aspects of the built environment and the residents' quality of life. There was evidence that a focus on safety and health requirements could be creating risk-averse environments which act against quality of life, particularly for the least frail residents. Staff morale was associated with attributes of a non-institutional environment for residents rather than with the facilities provided for the staff. The new tool for assessing building design has potential applications in further research and for care providers.

A life cycle analysis approach was used to assess the environmental impacts for three types of hotel buildings having various envelope configurations and materials, built in different climates: Algeria and France. The study assesses through a comparative approach the impact of building components on its energy performance and their environmental cost over the entire life cycle of the building. The life cycle analysis was performed using PLEIADES software tools. The results show that it is possible to reduce the energy requirements of both traditional and standard building envelopes by assigning low-consumption building scenarios. However, although these scenarios could reduce some environmental impacts, they could also enhance others. In order to improve the results of life cycle analysis, another variant that generates less impacts than previously simulated variants was developed by retaining the following environmental scenarios: superfluous material at the site, 5%; lifetime of doors and windows should be 30 years; coating life-time should be 10 years; use of natural gas for heating; wood energy for domestic hot water; consumption of cold water should be 0.2 m3/person/day; selective collection of glass, 50%; selective collection of paper, 30%; incinerated waste, 30%; and the produced waste should not be more than 1 kg/person/day.

Abstract Construction affects our environment to a significant extent and therefore, there is an increasing request for building materials and products in both new and old constructions to be evaluated with regard to their sustainability. This concerns both maintenance and restoration measures in an increasing way. These measures are necessary to keep our built environment in a reasonable state and to enable us to use them in the future. This also includes the extension of the life time of buildings. In this contribution most promising methods and criteria to evaluate the sustainability of maintenance or restoration processes and products are summarized and explained using two practical examples of building life cycles

Abstract Many studies and research point to a growing trend in industrial digitization. New materials, technologies and advanced automation tools are increasingly being promoted in the construction industry. With the increasing degree of digitization, various ways and methods of planning, management and control across different construction processes are also increasing. BIM is a unified information system that enables the sharing of documentation, supports communication, streamlines individual processes, helps eliminate errors and increases quality. Based on this fact, the paper analyses the current state of use of Building Information Modelling in planning and managing the life cycle of buildings in Slovakia and the Czech Republic. The current state of knowledge and use of BIM, defining the advantages and possible barriers to its use, examining the scope and potential of BIM implementation within the building life cycle and defining tools and applications used in time and financial planning of construction production were analysed. The paper also briefly examines how the implementation of BIM can affect selected key tasks of the preparation and valuation professions.
