With the rise of low-carbon economy, more and more investors understand and accept the concept of sustainable development, some investors have gradually shifted business focus to green buildings, but most are still on the sidelines. For investors, the most important consideration in their decision-making is the project's future benefits. The main aim of this paper is to identify incremental return on incremental costs of green buildings from the real estate investor’s perspective by analyzing a green residential building project. Based on the detailed analysis of incremental costs and benefits of the green building, the paper obtains the incremental investment rate of return using incremental analysis method. It certifies that there is a large benefit space for the developers to invest in green buildings.

Electrical energy usage in buildings is a challenging issue because many old buildings were not originally built to achieve energy efficiency. Thus, retrofitting old buildings to net-zero buildings can benefit both the owner and electric utilities. In this study, the BEC (building energy code) software was used to evaluate energy aspects of retrofitted buildings in compliance with Thailand’s building energy code to achieve a net-zero energy building. In addition, economic aspects were also studied to verify the feasibility for a project’s owner to invest in a retrofitted existing building. An existing residential building in Thailand was used as a case study. The results in terms of energy after retrofitting existing buildings into net-zero energy buildings show that the total energy consumption can be reduced by 49.36%. From an economic perspective, the investment cost for a retrofitted building can be compensated by energy saving in terms of discounted payback period (DPP) for approximately 4.36 years and has an IRR (internal rate of return) value of 19.23%. This result evidences the potential in both energy and economy for a project’s owner to invest in a retrofitted existing building in compliance with the building code, with potential for implementation with benefits on both electrical utilities and the project’s owner.

Green building has been proven having higher occupancy rate than conventional building. The occupancy rate of ENERGY STAR and LEED-certified green office building are 8% to 18% higher than conventional office building. Previous research has proved that occupants prefer to occupy green office building due to various green benefits. However, most of these researches were conducted on green office building. Therefore, this study is motivated to identify the influential factors for occupants to occupy green residential building. The aim of this study is to evaluate factors that influence occupants to occupy green certified residential building. 75 questionnaires were distributed among occupants of green certified residential building namely Molek Pine 4 and Ponderosa Lakeside Apartment in Johor Bahru. The results were analysed using frequency analysis. Location and good environment quality are the most significant factors that influence occupants to occupy the green certified residential building in Johor Bahru. This research is noteworthy for property industry players especially property developer in guiding the direction of green residential building development in accordance with occupants’ and market preferences.

Energy consumption, specifically in the building sector, is expected to rise. One potential way to reduce energy consumption, or to slow this increase, is to reduce the heat loss in residential homes. Silica aerogels have grown in popularity as an insulating material due to their extremely low thermal conductivity. However, the benefits of using silica aerogels as an insulator in residential buildings have not been thoroughly studied. To understand the benefits of using silica aerogels as a thermal insulator in residential homes, experimentally validated simulations were performed. The simulations were performed on a model of a full-scale residential house using the multiphysics software ANSYS FLUENT 2019 R2. The simulations helped predict the actual saving benefits of using aerogels as an insulator. Aerogels have the potential to be used as an insulator in both the walls and windows due to its semitransparency. The results showed that the average kWh savings using one half-inch layer of wall aerogel insulation coupled with window aerogel insulation was 20.9% for the single-family house compared to traditional insulation. On average, the energy lost through the windows was 39.1% lower when using aerogel insulation compared to standard insulating materials. The energy lost through the house walls was 13.3% lower on average when using a thin layer of aerogel insulation. While a thin layer of aerogel insulation provided a benefit when used in the house walls, the potential for savings per quantity used was greater in the windows.

Existing buildings are the massive percentage of the building stock, and therefore, are the key to improving efficiency; buildings account for an enormous share of the climate change crisis, and approximately 40% of the world total energy consumption (McArthur & Jofeh, 2015).
The Egyptian stock of buildings includes about 12 million buildings. 60% of these buildings are residential. The final electricity consumption of the residential buildings in 2010 was 51370 GWh and increased in 2014 to reach 62441 GWh. Thus the share of total energy consumption was 18.8% in 2010 and increased to reach 21.55% in 2014 ("Technology Roadmap - Energy efficient building envelopes.", 2013). Therefore, the residential sector plays an important role in the mitigation of energy consumption crisis, which is expected to increase.
The research field and initiatives in Egypt on the green buildings and green buildings retrofits are rare and, if existing, are weakly applied. Unlike in developed countries, there is a large research on building retrofits, e.g., the Residential Property Assessed Clean Energy (R-PACE) program and the weatherization assistance program (WAP) of the department of energy (DOE). Both are examples of the incentives to green building initiatives globally.
This paper discusses the challenge of greening the existing residential buildings in Egypt by demonstrating an analysis of the motives and the barriers to applying green measures in the Egyptian market.
The research methodology comprises the analytical-comparative method. In the analytical part; the paper identifies the current situation of the residential sector energy consumption in Egypt, and the benefits of greening existing buildings for tenants, investors, and owners.
In the comparative part, the current situation of Egypt's Green Market Business Case is compared with the international one, discussing the challenge of greening the residential buildings. The paper summarizes the opportunities to improve the building energy efficiency, incentives, and policies that are developed to address significant financial and technical awareness to building efficiency. These policies will help enable critical market actors to make decisions to promote energy efficiency in existing buildings.

<p class="Abstracttext-VITRUVIOCxSpFirst">The paper deals with the issue of the regeneration of the existing building heritage by framing the problems that characterize the relationships between users-buildings-neighbourhoods in a circular vision. Circular Economy concepts are well suited to the building and construction sector in cities. For example, refurbishing and adaptively reusing underutilized or abandoned buildings can revitalize neighborhoods whilst achieving environmental benefits. A systematic review of the literature and case studies has led to the identification of three areas of action of the CE in the regeneration of the built environment: a Macro-level (the public space), a Micro-level (the single component), a Meso-level (the building). However, the traditional approach of carrying out timely interventions aimed at responding to individual problems, be they of a structural, energetic, functional nature, relating to the building, the context or the single component is not entirely effective in terms of reformulation of the building characteristics. In this perspective, the paper suggests strategies of circular regeneration of residential buildings through adaptive solutions at room level, home level and urban in pursuit of human wellbeing.</p>

During the use of buildings it becomes necessary to carry out repair works including modernisation. Deciding on the choice of repair solutions is a difficult and complex task. Building administrators have to consider both, the benefits of some repair works, and limitations due to the availability of funds. Selection of a repair solution, bearing in mind the above, requires a comprehensive approach that will allow assessment of the building condition and determining the repair scope required. The research conducted by the authors was aimed at developing a decision-making model and its computer-aided implementation, taking into account a number of operating demands. The system algorithm proposed comprises five stages including: building condition assessment, building use value evaluation, repair classification, multiple variants of repair and the choice of repair solutions. The article describes individual stages of the model in detail, giving numerical application examples of the method for repair solution choice for five multi-family houses.

Since existing residential buildings are a significant global contributor to energy consumption and greenhouse gas (GHG) emissions, any serious effort to reduce the actual energy and carbon emissions of the building sector should explicitly address the carbon mitigation challenges and opportunities in the building stock. This research investigates environmentally and economically sustainable retrofit methods to reduce the carbon footprint of existing residential buildings in the City of Greater Dandenong as a case study in Metropolitan Melbourne, Australia. By categorizing energy use into various building age brackets and dwelling types that align with changes in energy regulations, we identified various retrofit prototypes to achieve a targeted 6.5-star and 8-star energy efficiency rating (out of a maximum 10-star rating system). The corresponding operational energy savings through different retrofit options are examined while also considering the quantity of materials required for each option, along with their embodied energy and GHG emissions, thus allowing a more comprehensive lifecycle carbon analysis and exploration of their financial and environmental payback times. Results show that when buildings are upgraded with a combination of insulation and double-glazed windows, the environmental benefits rise faster than the financial benefits over a dwelling’s lifecycle. The size or percentage of a particular dwelling type within the building stock and the remaining lifecycle period are found to be the most important factors influencing the payback periods. Retrofitting the older single detached dwellings shows the greatest potential for lifecycle energy and carbon savings in the case suburb. These findings provide households, industry and governments some guidance on how to contribute most effectively to reduce the carbon footprint of the residential building sector.

Countries around the world are making efforts to develop and introduce green building certification systems to save energy and reduce greenhouse gas emissions. As a result of these efforts, green certification systems are rapidly spreading. Consistent with this, certification systems are also being developed and research related to various technologies and regulations is ongoing. However, most research focuses on residential and commercial buildings and there is still a lack of scientific research on educational facilities. To fill the gap and support the former studies, this research statistically studies the economic effects of green certification systems on educational facilities. For this purpose, the benefits, i.g., building price and maintenance & repair costs, were examined for universities in Canada that were admitted to the Canadian Educational Institution. As shown by the results of this study, Leadership in Energy and Environmental Design (LEED)-certified buildings cost 49.9% more to build and had 25.6% lower maintenance and repair costs than non-LEED certified buildings.

The garden landscape of urban residential areas has significant environmental benefits, allowing people to get closer to nature and integrate with nature to relax and have some social benefits at the same time. This article is aimed at studying the effect of urban greening remote sensing on residential landscape construction. This paper uses the greening remote sensing image processing algorithm combined with the analysis method of SURF color remote sensing image and conducts the experiment based on the urban greening remote sensing on the residential area landscape architecture research. This article combines sustainable development strategies with innovative design methods to deeply study the role of urban greening remote sensing on the construction of residential landscape architecture. At the same time, the experiment in this article also proposes that the garden landscape of urban residential areas can provide entertainment for people, soothe residents’ mood, and achieve the best use of residential buildings. However, there are still some constraints in the development process of residential industry: insufficient government support, relatively backward technology of residential industrialization, lack of support and input from enterprises, and prejudice of people’s traditional concept towards it. The experimental results of this paper show that the remote sensing image features of buildings in residential areas and public areas are obvious. In the recognition of 46 training features and 34 detection features, the number of correct remote sensing recognition features is 32, and the green building image remote sensing recognition is good. The accuracy is 94%, which can meet the identification requirements of greening in the building. Combined with the specific conditions of urban greening and garden construction in my country, it can meet people’s entertainment needs and, to a certain extent, can also improve people’s life and cultural taste.

The existing building stock is recognised as a major contributor to total energy consumption and related carbon emissions around the globe. There is increased attention on the retrofit of existing building stock, especially residential buildings, as a way of curbing energy consumption and carbon emissions. Within this context, human nature connectedness (HNC) has the potential of further amplifying the benefits of sustainable buildings both from an energy conservation practice and tangible improvements to users’ satisfaction, health, and wellbeing. This study attempts to show a case study of the potential of using HNC through the adoption of biophilic design principles to improve a residential building performance. A terrace house located in Sydney, NSW, was used as a case study and proposed retrofit scenarios were simulated with DesignBuilder® and Rhinoceros/Grasshopper with a view of improved daylighting, thermal comfort, and energy consumption. The building performance is improved in terms of daylighting, thermal comfort, and reduced energy consumption, additionally enhancing HNC.

With prefabricated construction method deemed as an effective way to improve the environmental performance and sustainable development of the building industry, it is inevitably adopted in the scaled residence in the process of residential industrialization. However, the development of prefabricated residential buildings is still immature under the current market economy system, because the stakeholders involved in the process are not yet able to form a good cooperation mechanism and they are more inclined to keep their own interests. As a result, the market share of prefabricated residential buildings is relatively low. Therefore, it is necessary to conduct research on the stakeholders involved. By analyzing their costs and benefits, the reasons that really impede the population of prefabricated residential buildings can be found. In this paper, incremental cost allocation coefficient is introduced, the incremental cost difference under different assembly rates is considered, and the allocation ratio of the incremental cost input of the prefabricated building is analyzed based on game theory. The evolutionary game theory for government and real estate companies is established under the condition of bounded rationality with consumer participation. Then the effectiveness of the game theory is verified using empirical analysis, so as to provide reference for the authorities to promote the large-scale development of prefabricated residential buildings.

The acceleration of construction of cities and towns motivates the development of the construction industry. Prefabricated residential building is extensively concerned by the public for its small damages to the surrounding environment and high quality. In this study, different construction stages of the prefabricated residential building were analyzed, and factors influencing the construction cost in different stages were discussed. The construction technique, speed, civil work cost and environmental benefits were compared between the traditional concrete building and the prefabricated residential building. Moreover the differences of costs in different stages were compared in a real case. Several effective measures for controlling construction cost were put forward. The results demonstrated that the cost of the prefabricated residential building was much lower than that of the traditional concrete building. The suggestions for reducing construction cost can provide a reference for similar projects.

In Hong Kong, buildings consume 90% of the electricity generated and over 60% of the city’s carbon emissions are attributable to generating power for buildings. In 2018, Hong Kong residential sector consumed 41,965 TJ (26%) of total electricity generated, with private housing accounting for 52% and public housing taking in 26%, making them the two major contributors of greenhouse gas emissions. Furthermore, air conditioning was the major source consuming 38% of the electricity generated for the residential building segment. Strategizing building energy efficiency measures to reduce the cooling energy consumption of the residential building sector can thus have far-reaching benefits. This study proposes a hybrid simulation strategy that integrates artificial intelligence techniques with a building energy simulation tool (EnergyPlus™) to predict the annual cooling energy consumption of residential buildings in Hong Kong. The proposed method predicts long-term thermal energy demand (annual cooling energy consumption) based on short-term (hourly) simulated data. The hybrid simulation model can analyze the impacts of building materials, construction solutions, and indoor–outdoor temperature variations on the cooling energy consumed in apartments. The results indicate that using low thermal conductivity building materials for windows and external walls can reduce the annual cooling energy consumption by 8.19%, and decreasing the window-to-wall ratio from 80% to 40% can give annual cooling energy savings of up to 18%. Moreover, significant net annual cooling energy savings of 13.65% can be achieved by changing the indoor set-point temperature from 24 °C to 26 °C. The proposed model will serve as a reference for building energy efficiency practitioners to identify key relationships between building physical characteristics and operational strategies to minimize cooling energy demand at a minimal time in comparison to traditional energy estimation methods.

This paper outlines some of the background of and constraints facing the emergence of a new industry, focused not on buildings as such but on residential fit-out – the integrated kit-of-parts “behind your front door.” Residential application of the distinction between base building (support) and fit-out (infill), although sharing the same principles as the well-established office building and shopping mall sectors, is particularly important because it affects a very large market whose potential is not yet exploited but is arguably nascent. It is well understood that industrial manufacturing processes – now becoming “product service systems” in the consumer sector – are most effective and dynamic where individual users are directly served, as seen in the automotive and electronics/communications sectors. Construction of base buildings understood as “infrastructures for living” is capable of stimulating the evolution of a fit-out industry that will itself accelerate innovation and distribution of new domestic fit-out services and systems. In general, the creation of a genuine fit-out industry is not a technical or industrial design problem. Material subsystems and components like partitioning, bathroom and kitchen equipment, as well as “plug-and-play” piping and wiring are available or are being invented and approved in regulatory regimes internationally. While some smart products are still needed, the problem now is essentially a business proposition. By shifting to the provision of benefits rather than simply manufacturing products, companies may find a competitive advantage in a sector of the building industry now poised for an innovation leap. In the US and other developed countries, this is particularly compelling given the sustainability agenda, smart growth and increased demand for consumer-oriented production. In this perspective, the trend toward base building architecture allows the building industry to effectively come to terms with new and creative modes of industrial production.

Abstract Wooden construction materials have two climate benefits compared to non-wooden options: lower lifecycle emissions and a carbon storage potential. This study estimates the implications of replacing concrete buildings with wooden ones for a period of 35 years in Helsinki metropolitan area, Finland. The study has three main steps. First, the greenhouse gas (GHG) emissions difference between concrete and wooden buildings is estimated. Next, we select the most accurate carbon storage potential of wooden buildings. Finally, we compare future wooden and concrete building scenarios regarding the climate benefits for the metropolitan area. We use data provided by the regional authority of the study area on predicted residential building construction. According to our findings, switching to wooden construction in urban areas can have a significant climate benefit for the studied region. Increasing wooden construction can cut carbon emissions by 0.56 Mt and increase the carbon storage by 1.83 Mt in the study area, an amount that is four times bigger than the yearly emissions from traffic in the same urban area. The findings are not only useful for the city of Helsinki but also to other global cities which have committed to carbon neutral strategies and have sustainable forestry practices available.

Abstract Wood products are seen globally as an important solution to substitute nonrenewable materials in the construction sector to enhance the life cycle sustainability of buildings. Globally, the most prominent opportunities for sustainability change in housing production lie in multistory residential buildings, which are built mainly of concrete, steel, and bricks. The possibilities of achieving multiple benefits from the use of wood in multistory residential buildings have gained interest among scholars, especially in the 2000s. However, the research has been dominated by views of production (especially construction processes), while scientific knowledge of consumption (especially the occupational phase of buildings) remains very limited. Information about how consumers with differing views of sustainable consumption evaluate the quality of wooden building materials particularly is scarce. This study aimed to investigate consumer perceptions of wooden building product quality and examine how the perceptions connect with consumers' consciousness for sustainable consumption (CSC). The research data were gathered in 2018 by a postal survey sent to 1,000 people living in Finland (response rate 25.6%) and analyzed with exploratory factor analysis and the Mann-Whitney U test. According to the results, respondents' views of wooden building product quality indicators can be grouped into three factors: technical advantages, environmental sustainability of materials, and social benefits at home. The strength of CSC was found to be linked with respondents' views of wooden building product quality. The results of consumers' CSC views help actors involved in the wood and construction industries better meet consumer expectations both for different aspects of sustainability and for lifestyles.

The age of the Italian building heritage has prompted the Government to implement regulatory measures aimed at mitigating the seismic risk, encouraging anti-seismic interventions on residential buildings through specific tax benefits. This work intends to analyze the economic convenience associated with these building transformations from an appraisal perspective, proposing an analysis methodology aimed at evaluating the increase in market value of the transformed properties, and at identifying the most convenient among the various feasible interventions. The application to a case study allows highlighting the net economic benefits in the owners’ portfolios able to compensate the logistical inconveniences associated with this type of intervention, soliciting a greater awareness of seismic risk, and favoring private initiative at a widespread level.

The design and study of low carbon buildings is a major concern in a modern economy due to high carbon emissions produced by buildings and its effects on climate change. Studies have investigated (CFP) Carbon Footprint of buildings, but there remains a need for a strong analysis that measure and quantify the overall degree of GHG emissions reductions and its relationship with the effect on climate change mitigation. This study evaluates the potential of reducing greenhouse gas (GHG) emissions from the building sector by evaluating the (CFP) of four hotpots approaches defined in line with commonly carbon reduction strategies, also known as mitigation strategies. CFP framework is applied to compare the (CC) climate change impact of mitigation strategies. A multi-story timber residential construction in Quebec City (Canada) was chosen as a baseline scenario. This building has been designed with the idea of being a reference of sustainable development application in the building sector. In this scenario, the production of materials and construction (assembly, waste management and transportation) were evaluated. A CFP that covers eight actions divided in four low carbon strategies, including: low carbon materials, material minimization, reuse and recycle materials and adoption of local sources and use of biofuels were evaluated. The results of this study shows that the used of prefabricated technique in buildings is an alternative to reduce the CFP of buildings in the context of Quebec. The CC decreases per m2 floor area in baseline scenario is up to 25% than current buildings. If the benefits of low carbon strategies are included, the timber structures can generate 38% lower CC than the original baseline scenario. The investigation recommends that CO2eq emissions reduction in the design and implementation of residential constructions as climate change mitigation is perfectly feasible by following different working strategies. It is concluded that if the four strategies were implemented in current buildings they would have environmental benefits by reducing its CFP. The reuse wood wastes into production of particleboard has the greatest environmental benefit due to temporary carbon storage.

The integration of photovoltaic modules into the building structure is a challenging task with respect to power generation of PV module and the effect of incident solar radiation. The performance of building integrated photovoltaic (BIPV) modules varies depending upon the orientation and azimuth angle of the building. In this work, the year-round performance and economic feasibility analysis of grid-connected building-integrated photovoltaic (GBIPV) modules is reported for the hot and humid climatic regional condition at Kovilpatti (9°10′0′′N, 77°52′0′′E), Tamil Nadu, India. The appropriate mounting structures are provided, to experimentally simulate the performance of GBIPV modules at various orientations and inclination angles (0° to 90°). The result indicated that the optimum orientation for installation of BIPV modules in the façade and walls is found to be east while that for a pitched roof south orientation is recommended. The overall average annual performance ratio, capacity utilisation factor, array capture loss and system losses are found to be 0.83, 23%, 0.07 (h/day), and 0.17 (h/day), respectively. In addition, the economic feasibility of grid connected PV system for residential buildings in Tamil Nadu, India is analysed using HOMER by incorporating both a net metering process and electricity tariff. Practical application: Grid-connected building-integrated photovoltaic system has many benefits and barriers by being installed and integrated into the building structure. The application of GBIPV in building structures and its orientation of installation needs to be optimised before installing into buildings. This study will assist architects and wider community to design buildings facades and roofs with GBIPV system which are more aesthetic and account for noise protection and thermal insulation in the region of equatorial climate zones. By adding as shading devices, they can reduce the need for artificial lighting, and moderate heating or cooling load of the buildings.

Speaking about building retrofit in Europe, the attention is often focused on the residential building stock built after the Second World War, which represents the 75% of the total number of buildings present on the territory. Recently many cities are encouraging campaigns of retrofit of the housing heritage built after the Second World War, since, in terms of cost, time, financing, consumption, and sustainability, the practice appears more convenient than building anew. To maximize the benefits of these retrofit campaigns, it is essential to promote multi-purpose and innovative strategies considering contemporarily architectural, functional and structural aspects. In the field of housing, in particular, it is necessary to develop new models able to answer to the new living style of a dynamic society. In fact, today as in the past, one of the downfalls of the housing sector is failing to recognize the human dimension within the designing process. This paper evaluates past architectural practices to achieve adaptability and flexibility in the residential sector and evaluate strategies for integrated retrofit based on two macro-areas: architectural/societal/functional and structural/technological/constructional.

The article presents the results of a complex experimental-analytical research of residential development energy parameters - survey of construction sites and determination of calculated energy parameters (resistance to heat transfer) considering their technical condition. The authors suggest a methodology for assessing residential development energy parameters on the basis of construction project’s structural analysis with the use of advanced intelligent collection systems, processing (self-organizing maps - SOM) and data visualization (geo-informational systems - GIS). SOM clustering permitted to divide the housing stock (on the example of Arkhangelsk city) into groups with similar technical-operational and energy parameters. It is also possible to measure energy parameters of construction project of each cluster by comparing them with reference (normative) measures and also with each other. The authors propose mechanisms for increasing the area’s energy stability level by implementing a set of reproduction activities for residential development of various groups. The analysis showed that modern multilevel and high-rise construction buildings have the least heat losses. At present, however, ow-rise wood buildings is the dominant styles of buildings of Arkhangelsk city. Data visualisation on the created heat map showed that such housing stock covers the largest urban area. The development strategies for depressed areas is in a high-rise building, which show the economic, social and environmental benefits of upward growth of the city. An urban regeneration programme for severely rundown urban housing estates is in a high-rise construction building, which show the economic, social and environmental benefits of upward growth of the city.

Abstract Based on synergic evidence-based design principles, building practices can achieve sustainable benefits throughout the life cycle. Taking example of an off-grid residential nearly zero energy building (NZEB) in China’s severe cold zone, the application and sustainability assessment of sustainable technologies can be comprehensively achieved through a closed-loop process: preliminary research, technology development & evaluation, on-site construction and feedback & optimisation. The Steppe Ark is one of such a residential building that takes synergic evidence-based design strategies, proposing and validating three types of technology strategies: integrated design of space based on function and performance, high performance passive technology and efficient active technology. The results show that: (1) the NZEB-oriented building envelope improves the thermal stability of the building, with indoor temperatures decreasing by only 0.07°C per hour when no equipment in operation; (2) the variable multifunctional façade and daylight reflectors have good lighting and insulation energy efficiency, with a combined energy saving rate of 22.1%; (3) Flat gravity heat pipes and thermal storage materials (bricks and PCM) have good performance in terms of heat storage and release. The average indoor daytime temperature can be increased by 3.80°C; the daily temperature difference can be reduced by 52.85% compared to the control group; (4) Stirling motors generate electricity while utilizing the waste heat for the building’s floor heating system; (5) the 5.5kWp BIPV system can generate 6.65MWh of electricity per year. This study proposes a pathway for assessing the suitability of building technology through synergic evidence-based design principles. The analysis shows that three types of technology strategies in off-grid residential NZEBs in the severe cold zone of China can achieve good environmental and economically sustainable benefits.

Nowadays, buildings renovation is a subject of special interest since the building and construction sector is the main body responsible for energy consumption and emissions. Hence, it is necessary to concentrate on refurbishment to achieve Europe’s climate neutrality by 2050 according to European Agenda goals. The BIM4EEB Project, a BIM-based fast toolkit for the efficient renovation of residential buildings, directs the attention toward developing an exhaustive toolkit based on Building Information Modeling (BIM) to be adopted in the renovation of existing residential buildings, to make the flow of information efficient, decreasing intervention working time while improving building performances, quality, and comfort for inhabitants. BIM4EEB is developing a BIM management system connected to an operational and multifunctional toolkit for various architecture, engineering, and construction (AEC) stakeholders, integrating a set of tools for improving BIM adoption in renovation environments based on an interoperable flow of information. This paper presents the Horizon2020 Project and the framework used to develop the toolkit. In addition, the first outcomes of the toolkit development are outlined. The validation procedure in real environments has started to demonstrate the efficacy and applicability of the methodology and tools. Although the project is still in progress, benefits connected to the framework and the BIM-based toolkit result in an enhanced building renovation process.

The article considers normative-legal, town-planning, technical and technological aspects of the problem of deployment of mass reconstruction and modernization of large-block residential buildings of the first mass series. Analysis and generalization of practical experience in the design and implementation of mass reconstruction of residential buildings of the first mass series in Ukraine and abroad shows that with the introduction of innovative approaches to the design of spatial planning and design solutions, application of modern and well-established technologies for their reconstruction economic, resource-saving, energy-saving, environmental protection and architectural and aesthetic benefits. The analysis of modern researches testifies to expediency of introduction of methods of reconstruction. An important aspect of mass reconstruction is the economic attractiveness for investors, this parameter is most widely discussed in this article. It is also important that the moral obsolescence of the building began much earlier than the physical, and the needs of people and the requirements for comfort increased significantly, which suggests the need for mass reconstruction of buildings of the first mass series. The condition for the deployment of mass reconstruction and modernization of large residential buildings of the first mass series is a comprehensive justification of its social, urban, regulatory and technological feasibility, as well as economic attractiveness for investors. This provision is taken as the task of this article. Analysis and generalization of normative-legal, social and technological aspects of reconstruction of large-block residential buildings of the first mass series and practical experience of designing and implementation of such reconstruction are accepted as the main research methods. On the example of the city of Chernivtsi the scheme of building of the city was developed and the percentage of building by buildings of the first mass series was calculated. This allows you to pay attention to the mass nature of the issue.

Rapid population growth has led to significant demand for residential buildings around the world. Consequently, there is a growing energy demand associated with increased greenhouse gas (GHG) emissions. The residential building energy demand in arid countries such as Saudi Arabia is supplied with fossil fuel. The existing consumption pattern of fossil fuels in Saudi Arabia is less sustainable due to the depletion of fossil fuel resources and resulting environmental impacts. Buildings built in hot and arid climatic conditions demand high energy for creating habitable indoor environments. Enormous energy is required to maintain a cool temperature in hot regions. Moreover, climate change may have different impacts on hot climatic regions and affect building energy use differently. This means that different building interventions may be required to improve the performance of building energy performance in these geographical regions, thereby reducing the emissions of GHGs. In this study, this framework has been applied to Saudi Arabia, a hot and arid country. This research proposes a community–government partnership framework for developing low-carbon energy in residential buildings. This study focuses on both the operational energy demand and a cost-benefit analysis of energy use in the selected geographical regions for the next 30 years (i.e., 2050). The proposed framework primarily consists of four stages: (1) data collection on energy use (2020 to 2050); (2) setting a GHG emissions reduction target; (3) a building intervention approach by the community by considering cost, energy, and GHG emissions using the Technique for Order of Performance by Similarity to the Ideal Solution (TOPSIS) to select the best combinations in each geographical region conducting 180 simulations; and (4) a clean energy approach by the government using grey relational analysis (GRA) to select the best clean energy system on the grid. The clean energy approach selected six different renewable power generation systems (i.e., PV array, wind turbine, hybrid system) with two storage systems (i.e., battery bank and a combination of electrolyte, fuel cell, and hydrogen tank storage). This approach is designed to identify the best clean energy systems in five geographical regions with thirty scenario analyses to define renewable energy-economy benefits. This framework informs through many engineering tools such as residential building energy analysis, renewable energy analysis, multi-criteria decision analysis (MCDA) techniques, and cost-benefit analysis. Integration between these engineering tools with the set of energy policies and public initiatives is designed to achieve further directives in the effort to reach greater efficiency while downsizing residential energy demands. The results of this paper propose that a certain level of cooperation is required between the community and the government in terms of financial investments and the best combinations of retrofits and clean energy measures. Thus, retrofits and clean energy measures can help save carbon emissions (enhancing the energy performance of buildings) and decrease associated GHG emissions, which can help policy makers to achieve low-carbon emission communities.

In the U.S., approximately 47% of the total electricity use comes from residential buildings. Most of the residential buildings use HVAC system to ventilate, cool, or heat the indoor environmental spaces mechanically, rather than using natural outdoor air in transition seasons, even though the outdoor environmental conditions are favorable for indoor thermal comfort. In this case, an HVAC system using mixed-mode ventilation with an appropriate ratio of using indoor air and outdoor air could decrease the energy use in residential buildings. This research uses high-granular HVAC electricity use data with indoor thermostat data and outdoor weather data from residential buildings in Austin, Texas, to evaluate the benefits of energy and economics when using HVAC mixed-mode ventilation in spring and fall transition seasons. The results demonstrate that the household owners could save approximately 150.79 kWh of total HVAC energy use and 24.41% of HVAC cost in spring transition months (April/May), and similarly, 143.86 kWh of energy use and 27.2% cost savings in fall transition months (October/November). The results could support further study to use automatically operated windows for natural ventilation to reduce energy use in residential buildings toward sustainable development.

The paper overviews the current energy demand trends in the building sector for the Arab region using reported historical energy consumption. Moreover, the paper describes the current energy efficiency policies and regulations for all the Arab countries specific to both residential and commercial buildings. Finally, the paper evaluates potential benefits for large-scale energy efficiency programs specific to new and existing building stocks within the Arab region using a bottom-up analysis approach. The analysis of the available energy consumption for all the Arab countries has shown that the Arab region presents a significant variation in energy consumption levels between its sub-regions and countries. Indeed, the Arab region includes oil-producing countries such as Saudi Arabia with the largest energy use per capita in the World with over 9000 kWh/person of electricity used annually in buildings. However, the same region has the least developed countries such as Sudan and Yemen with the lowest energy use per capita in the World with barely 100 kWh/person/year of electrical consumption. The review of the existing regulations has indicated that several Arab countries have not implemented any energy efficiency codes and standards for building envelope, lighting, heating and cooling equipment, and appliances. A cost-effectiveness analysis has indicated that the Arab region can incur significant benefits in upgrading the energy efficiency of its new and existing buildings especially its households. Specifically, the adoption and the enforcement of stringent energy efficiency codes for new residential and commercial buildings can result in a reduction of 12.7 TWh/year in final annual energy consumption for the Arab region. Moreover, retrofit programs targeting existing buildings can save up to 470 TWh or a third of the building sector final energy consumption per year after 2030. Combining comprehensive energy efficiency requirements for new buildings and extensive retrofit programs for existing buildings would reduce the total final energy consumption of the building sector in the Arab region by 600 TWh by 2030 and by 900 TWh by 2050 if all the energy programs start to be implemented by 2020.

Nowadays, people spend an average of 87% of their time inside buildings, and about 69% at home. Hence, it is essential to ensure the highest possible level of indoor air quality (IAQ). Providing that the quality of the outdoor air is acceptable, the IAQ level is improved by increasing the ventilation rates. However, this means that a larger volume of air must be cooled down or warmed up to ensure the same level of thermal comfort. The aim of this study was to conduct a cost–benefit analysis of the IAQ in residential buildings. A case-study building was defined, and three sets of materials with different pollution emission levels were chosen: High, low, and very low. For each option, the ventilation rates required to have the same IAQ level were calculated, and the consequent energy consumption and costs were estimated by means of dynamic thermal simulation. The results show the range of the initial capital cost that could be compensated for by lower running costs, and the effect of each energy and economic input assumption on the appraisal of the affordable capital cost. In the discussion, insights into the IAQ co-benefits are also given.

Green buildings have been gaining in popularity over the past few years in Jordan. This is attributed to environmental and financial reasons directly related to energy consumption and cost. Energy sector in Jordan faces two main challenges which are the fast growing of energy demand and the scarcity of resources to fulfill this demand. Green buildings can save energy by designing them as near Zero Energy Buildings, where they produce amount of energy almost equal the amount of energy they consume. In special cases green buildings can be designed as Net zero energy buildings, where they produce as much energy as they consume. Jordan government encourage people to adopt net zero green buildings by issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, that allows selling excessive electricity to electricity companies. Despite these benefits of green buildings, they are not yet the norm in the building sector in Jordan. This can be attributed to the high construction cost of green building compared to traditional one. However, this may not be true if the whole life cycle cost of the building is considered, in which the cost not only include design and construction but also operation and maintenance as well. This paper aims to provide real life cycle cost analysis for a typical residential building in Jordan, and to search different effective building strategies and design scenarios that will lead to a successful near Zero Energy Building. The search will apply main green building strategies recommended for Jordan climatic zone. The outcome of this study is a list of best economically feasible design solutions and system selections that result in near Zero Energy Building in Jordan for residential buildings.

This research tries to investigate, in the current condition of the Italian real estate market, the economic advantage of investing in energy retrofitting of existing buildings or in expenditure aimed at obtaining higher energy performances in the construction phase of new buildings. A cost-benefit analysis is developed referring to the construction industry entrepreneur. Firstly, the increase in value due to a different measurement of the energy performance of new buildings or newly redeveloped residential buildings is achieved through an innovative statistical approach. Energy performance is measured by taking as a reference the category of energy certification, as required by European legislation. In the estimate of the contribution, the measurement of energy performance, expressed on an ordinal scale, is treated as a categorical variable in the implementation of an iterative regression model, called the alternating least squares model. Afterwards, this contribution is compared to the cost of sustainable building, trying to define a percentage increase in cost compared to a minimum condition according to different and increasing levels of energy performance. In the developed case studies, the comparison between likely benefits and investment spending showed that the entrepreneur would have no convenience at an expense for energy retrofitting while obtaining a positive balance in the construction phase of new buildings. The financial advantage grows if the investment is aimed at achieving the best energy performance and in areas where the price level of the real estate market is lower. The finding can be used as a guide for construction industry investors to make decisions in energy-efficient residential buildings production or transformation.

Modelling energy systems is of great interest since it can help to analyse building energy behaviour and to optimize control strategies. Grey-box modelling is one of the three fundamental modelling approaches for developing energy models. Due to its simplicity and offering several benefits, it has been widely used to handle building-technology challenges such as building load estimate, control and optimization, synthetic data generation for prediction, load peak management and grid integration. This review research looked at several areas of grey box modelling for building energy systems. Here we analyse three main directions, first one is modelling thermal dynamics of buildings, second one analysing approach used to model most used building electrical appliances and third one is renewable systems used to produce thermal water for residential use.

The purpose of the study is to identify the main typological, space-planning, constructive, stylistic and town-planning features of residential buildings designed by the Municipal union of Novosibirsk housing cooperatives in the years of the first five-year plan. Research objectives: 1) To substantiate the need for a transition to stone construction and the benefits of the development of quarterly residential buildings in Novosibirsk during the first five-year plan; 2) Determine the main types and types of housing, the development of which was engaged Gorshilsoyuz in the study period; 3) Analyze the most characteristic objects designed by Gorzhilsoyuz in the 1930s. The method of work is based on a comprehensive analysis of archival materials from the Novosibirsk State Archive (GANO) and funds of the Museum of the History of Architecture of Siberia named after S.N. Balandin (Novosibirsk), as well as literary sources and materials of periodicals. The novelty of the research lies in the fact that for the first time, based on an analysis of residential building projects created by the Gorzhilsoyuz, their architectural and typological features and compositional and stylistic features are identified and compared in detail. Founded in 1925, the Municipal union of Novosibirsk housing cooperatives (Gorzhilsoyuz) began its activities with the design of wooden residential buildings for housing cooperatives. In the years of the first five-year plan, this organization switched to the design of stone multi-apartment residential buildings based on socialist type housing principles. If in the previous period, most residential buildings had a unified space-planning solution, which did not include other functions besides housing, in 1928–1932 the city began to embody the original projects of new types of not only multi-family buildings, but also quarterly residential complexes, which included in their structure public housing and service facilities. The first example of a quarter residential development of the city was the “garden-quarter of a new type” of the housing cooperative “Pechatnik”. The design of residential buildings involved professionals Gorzhilsoyuz. The corner multisection apartment building had in the ground floor: shops, a dining room, a pharmacy, a kindergarten, a red corner; in the basement were: showers, bathrooms and laundry. Decorative belts and rizalits were the main architectural elements of the main facade. In 1929–1930 housing cooperatives “Medrabotnic” and “Khimik” built two corner multi-section residential buildings according to the projects of the Gorzhilsoyuz. Multi-apartment building “Medrabotnic” consists of four sections. Standard ordinary end sections had two apartments on the floor: three- and four-room apartments, each of which housed a kitchen, a bathroom, and a bathroom. A store was designed on the first floor of the rotary section, and on each floor above are two three-room apartments (without bathrooms) and one four-room (second to fourth floor) apartments. The residential building of the “Khimik” was the first five-story building in Novosibirsk and was conceived as a communal house. The house provided separate sleeping areas for: adults and children. However, due to the change in the ideological line of the government, the project was converted into an apartment building with shops on the ground floor. The facades of the house spatially overlap with the facades of the building “Medrabotnic”. The residential four-storey building of the housing cooperative “Rabochaya piatiletka”, built in 1930 according to the drawings of the Gorzhilsoyuz, was designed as a communal house. The project was supposed to accommodate people in separate age groups. On the ground floor there was a dining room with a kitchen, administrative rooms and bedrooms for the elderly. On the second floor there were the bedrooms of adults and children of eight years of age. The third and fourth floors were occupied by bedrooms of adults and children up to 16 years. Half of the fourth floor had social functions. The basement was allocated for laundry, boiler room and pantry products. However, in connection with the Decree of the Central Committee of the CPSU (b) “On work on the restructuring of life” (dated May 16, 1930), the dormitory was re-planned, and later became an administrative building.

Residential condominium projects currently utilize the benefits of building information modeling (BIM) in many aspects, although the use of the BIM in the facility management aspect has not been popularized as much as it should be. This research aims to study the BIM data necessary for condominium facility management nowadays so that building managers can accurately receive the BIM's building information and effectively handle the building management. Several interviews were conducted with five personnel from real estate companies of condominium projects which used the BIM to explore guidelines for the BIM data preparation for condominium management and analyzing the data with content analysis. The research results presented: (1) the BIM data that the condominium managers need for building maintenance; (2) the characteristics of data preparation for the building's facility management; (3) the determination of duties to perform various processes for the management of building facility which consists of the Level of Development (LOD) and the Level of Information (LOI); (4) the determination of management of information transmission and exchange for the building facility management. We concluded that BIM facility management could solve the problems of scattered or conflicting data by clearly identifying and checking specific building areas. In addition, it can reduce the working steps in a condominium development. Therefore, the research results can help real estate developers and those involved in project development and condominium facility management learn how to efficiently and effectively manage condominium facilities.

The increasing number of residential buildings that are installing distributed energy resources enforces the need for schemes to facilitate a local energy balance. With the continuing evolution of Internet of Things (IoT) technology, Peer-to-Peer (P2P) energy trading is becoming a viable solution to incentivize prosumers and promote efficient energy sharing in a community. This paper develops a model to quantitatively analyze the potential benefits of P2P energy trading for residential buildings that have installed photovoltaic battery systems. The integration of the bidding strategy into a residential energy-management system is feasible to realize cost savings for prosumers. However, the coordination between the bidding strategy and the optimal scheduling of energy has received far too little attention. To better participate in the P2P market, we propose a novel separate bidding energy-management system (SBEMS) that can realize rolling optimal energy scheduling while determining energy bids. The model’s effectiveness is verified via case studies of 75 participants in a community. The results indicate that the prosumers can reduce their costs by up to 24% by employing the proposed SBEMS in the P2P market. In addition, the proposed method is found to offer better performance in terms of economic and technical indices.

Circular building has gained considerable attention in the Netherlands during the past decade. It is rooted in concepts such as circular economy (CE) and Cradle-to-Cradle (C2C®), accentuating the closing and coupling of material loops to establish effective and efficient resource flows. Moreover, those concepts adhere to a systemic, holistic worldview, incorporating multiple flows and values. Although social aspects, such as health, wellbeing, and social inclusiveness, are generally part of circular building principles, specific benefits for end-users are not. This paper explores the synergistic potential of circular and flexible (Circ-Flex) criteria from the perspective of enhanced control and convenience for residents. The hypothesis is that without integrating the user domain, replicability of circular building concepts on a larger residential scale cannot be done in a truly sustainable manner. The paper is structured around two objectives: (1) further identifying the relationship between flexible and circular building; and (2) exploring the impact of circular, flexible building concepts and practices for the users of multi-family housing, specifically regarding interior partitioning. The research follows a mixed-mode methodology comprising of literature review, case study, expert consultations and a quick-scan assessment. Eleven Circ-Flex criteria are explored, grouped in three categories: flexibility capacity, circularity capacity, and user capacity. These criteria are applied to two partitioning variants, whilst exploring the performance regarding material circulation and user benefits.

Due to the increasing spread of residential heating systems electrically powered, buildings show a great potential in producing demand side management strategies addressing their thermal loads. Indeed, exploiting the intrinsic characteristics of the heating/cooling systems (i.e. the thermal inertia level), buildings could represent an interesting solution to reduce the electricity peak demand and to optimize the balance between demand and supply. The objective of this paper is to analyse the potential benefits that can be obtained if the electricity demand derived from the heating systems of a building cluster is managed with demand response strategies. A simulation-based analysis is presented in which a cluster of residential archetypal buildings are investigated. The buildings differ from each other for construction features and type of heating system (e.g. underfloor heating or with fan coil units). By supposing to be able to activate the energy flexibility of the single building with thermostatic load control, an optimized logic is implemented to produce programmatically an hourly electricity peak reduction. Results show how the involvement of buildings with different characteristics depends on the compromise that wants to be achieved in terms of minimization of both the rebound effects and the variation of the internal temperature setpoint.

This paper uses SketchUp and OpenStudio to design and optimize the multiperformance parameters of the near-zero energy consumption residential building scheme stage. By establishing a basic model, the performance parameters such as insulation thickness, typical outer window, window-to-wall ratio, and their contribution rates within the threshold range are optimized for energy conservation; simulate the energy consumption of the determined multiperformance parameter combination scheme, select the most energy-saving scheme, and calculate its energy-saving contribution rate; calculate the life cycle cost of the above schemes, select the scheme with the lowest cost, and analyze its economic benefits; select energy-saving cost and economic benefit, and calculate energy-saving contribution rate and economic benefit. Finally, through the comparative analysis of the design and test data, this paper concludes that EnergyPlus will optimize the multiperformance parameters of the near-zero energy consumption residential building scheme stage. At the same time, the multiobjective optimization method and process of the passive energy-saving technology of the near-zero energy consumption building proposed in this paper, as well as the technology combination template under different needs, provide a reference for the selection of the technology path.

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

In this paper, a review of the adoption status of energy efficiency and renewable energy technologies is presented, specific to US residential buildings. Various technologies are reviewed and categorized as either their relative “higher adoption” or “lower adoption” rates within the US housing stock. More importantly, the review analysis investigates the main factors associated with their high or low adoption rates. Specifically, the paper provides a background of the historical progression of energy efficiency programs as well as sustainability certifications and standards for buildings. The review then analyzes specific building energy efficiency and renewable energy technologies applied to US residential buildings and their adoption rates. The review analysis indicates that building technologies are more frequently adopted for multiple reasons including requirements by codes and standards, incentives through green certifications, low implementation costs, and acceptance and popularity by the public. In contrast, technologies with low adoption rates have higher payback periods, are not required or highly incentivized through codes and certifications, have limited promotion about their benefits, or are not compatible with existing systems. By determining the reasons for the high and low adoption rates, mitigation options can be identified to increase the application of sustainable energy technologies in designing and retrofitting buildings.

Modular construction is widely used for residential buildings of 4 to 8 storeys. In the context of open building systems, modular construction provides a systemised approach to design in which the benefits of prefabrication are maximised. There is demand to extend this form of construction to more than 12 storeys for residential buildings. This paper presents a review of modular technologies, and describes load tests and analysis on light steel modular walls that are used to justify the use of light steel technology to support higher loads. For taller modular buildings, the effect of installation and geometric inaccuracies must be taken into account and it is proposed that maximum out of verticality of a vertical group of modules is 50mm relative to ground datum. Using these geometric tolerances, the notional horizontal force used to evaluate stability of a group of modules should be taken as a minimum of 1% of the applied vertical load on the modules. Robustness to accidental load effects is important in all high-rise buildings and it is proposed that the tie force in the connections between modules should be taken as not less than 30% of the total vertical load applied to the module in both horizontal directions.
