Abstract The concept of green buildings has recently arisen in order to contribute to solving some environmental, energy and economic issues. To meet the green building requirements, this paper describes an integrated design approach to improve the energy and water efficiency of the mid-rise residential buildings in Jordan using the eQUEST energy simulation tool. The results show that savings of 77.9% in the annual requirements of electricity, 65.0% in the requirements of diesel oil and 19.5% in the indoor water consumption can be achieved. Finally, the Jordanian green building model had achieved 44 points in the Leadership in Energy and Environmental Design green building rating system and will have the ‘Certified’ classification.

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.

Residential space and water heating accounts for around 13% of the greenhouse gas emissions of the UK. Reducing this is essential for meeting the national emission reduction target of 80% by 2050 from the 1990 baseline. One of the strategies adopted for achieving this is focused around large scale shift towards electrical heating. This could lead to unsustainable disparity between the daily peak and off-peak electricity loads, large seasonal variation in electricity demands, and challenges of matching the short and long term supply with the demands. These challenges could impact the security and resilience of UK electricity supply, and needs to be addressed. Rechargeable Thermal Energy Storage (TES) in residential buildings can help overcome these challenges by enabling Heat Demand Shifts (HDS) to off-peak times, reducing the magnitude of the peak loads, and the difference between the peak and off-peak loads. To be effective a wide scale uptake of TES would be needed. For this to happen, the benefits and impacts of TES both for the demand side and the supply side have to be explored, which could vary considerably given the diverse physical, thermal, operational and occupancy characteristics of the UK housing stock. A greater understanding of the potential consequence of TES in buildings is necessary. Such knowledge could enable appropriate policy development to help drive the uptake of TES or to encourage development of alternative solutions. Through dynamic building simulation in TRNSYS, this work generated predictions of the space and water heating energy and power demands, and indoor temperature characteristics of the UK housing stock. Twelve building archetypes were created consisting of: Detached, semi-detached, mid-terrace and flat built forms with thermal insulation corresponding to the 1990 building regulation, and occupied floor areas of 70m2, 90m2 and 150m2. Typical occupancy and operational conditions were used to create twelve Base Case scenarios, and simulations performed for 60 winter days from 2nd January. HDS of 2, 3 and 4 hours from the grid peak time of 17:00 were simulated with sensible TES system sizes of 0.25m3, 0.5m3 and 0.75m3, and water storage temperatures of 75°C and 95°C. Parametric analysis were performed to determine the impacts and benefits of: thermal insulation equivalent to 1980, 1990 (Base Case), 2002 and 2010 building regulation; locations of Gatwick (Base Case) and Aberdeen; heating durations of 6, 9 (Base Case), 12 and 16 hours per day; thermostat settings of 19°C, 21°C (Base Case) and 23°C, and number of occupiers of 1 person and 3 persons (Base Case) per household. Good correlation was observed between the simulated results and published heat energy consumption data for buildings with similar thermal, physical, occupancy and operational conditions. The results allowed occupied space temperatures and overall daily and grid peak time energy consumption to be predicted for the range of building archetypes and parameter values considered, and the TES size necessary for a desired HDS to be determined. The main conclusions drawn include: The overall daily energy consumption predictions varied from 36.8kWh to 159.7kWh. During the critical grid peak time (17:00 to 21:00) the heat consumption varied from 4.2kWh to 58.7kWh, indicating the range of energy demands which could be shifted to off-peak times. On average, semi-detached, mid-terrace, and flat built forms consumed 7.0%, 13.8% and 22.7% less energy for space heating than the detached built form respectively. Thermal insulation changing from the 1990 building regulation level to the 1980 and 2010 building regulation levels could change the mean energy use by +14.7% and -19.6% respectively. A 0.25m3 TES size with 75°C water storage temperature could enable a 2 hour HDS, shifting 4.3kWh to 11.7kWh (mean 8.7kWh) to off peak times, in all 70m2 Base Case archetypes with the 60 day mean thermal comfort of 100%, but with the minimum space temperature occasionally dropping below an 18°C thermal comfort limit. A 0.5m3 TES size and water storage of 95°C could allow a 3 hour HDS, shifting 9.8kWh to 28.2kWh (mean 18.7kWh) to off peak times, in all 90m2 Base Case archetypes without thermal comfort degradation below 18°C. A 0.75m3 TES with a 95°C water temperature could provide 4 hour HDS, shifting 13.9kWh to 47.7kWh (mean 27.2kWh) to off peak times, in all 150m2 Base Case archetypes with 100% mean thermal comfort but with the 60 day minimum temperature occasionally dropping below the 18°C thermal comfort limit in the detached built form. Improving the thermal insulation of the buildings was found to be the best way to improve the effectiveness of HDS with TES, in terms of the demand shift period achievable with minimal thermal comfort impact. A 4 hour HDS with 100% thermal comfort is possible in all 90m2 floor area buildings with a 0.25m3 tank and a water storage temperature of 75°C provided that the thermal insulation is as per 2010 building regulation. Recommendations for further research include: 1) creating larger number of archetype models to reflect the housing stock; 2) using heat pumps as the heat source so that the mean effect on the grid from electric heating loads can be predicted; 3) taking into account the costs associated with taking up HDS with TES, in terms of capital expenses and space requirement for housing the TES system; 4) considering alternative methods of heat storage such as latent heat storage to enhance the storage capacity per unit volume; and 5) incorporating zonal temperature control, for example, only heating rooms that are occupied during the demand shift period, which could ensure better thermal comfort in the occupied space and extend the demand shift period.

Dentre diversas razões para que apenas um empreendimento imobiliário residencial concluído até maio de 2013, tenha conquistado uma certificação ambiental no Brasil, o fato de que empreendimentos sustentáveis contabilizam aumento de custos com a obra, com o processo de certificação e com consultores, em relação a empreendimentos convencionais é a dificuldade mais relevante na opinião dos empreendedores. O custo adicional da obra sustentável é uma dificuldade para construir de forma sustentável citada por 82% dos incorporadores imobiliários que responderam a enquete apresentada neste trabalho. Esse fato pode estar inibindo o desenvolvimento de empreendimentos sustentáveis por parte das empresas incorporadoras do país. Uma possível solução para reduzir esta barreira econômica é a identificação de aspectos que agreguem sustentabilidade a empreendimentos residenciais e apresentem custos de implantação menores ou iguais à seus equivalentes convencionais. O objetivo deste trabalho é a identificação dos requisitos do Processo Aqua para Edifícios Habitacionais (2013, versão 2), que não agregaram custos adicionais ao empreendimento residencial referencial Reserva Anauá, destinado às famílias com renda entre 6 e 10 salários mínimos e podem ser replicados em outros empreendimentos com tipologia similar. Assim, os empreendedores podem incorporar até 193 exigências dessa certificação a seus projetos residenciais, para torná-los mais sustentáveis, sem agregar custos adicionais em relação empreendimentos convencionais.Among several reasons why only one residential real estate development completed by May 2013, has achieved an environmental certification in Brazil, the fact that there are additional costs with the green construction, the certification process and the consultants are the most relevant difficulties for the entrepreneurs to develop sustainable projects. The green premium is a difficulty to build green cited by 82% of the developers who responded to the survey presented in this dissertation. This may be inhibiting the development of sustainable residential real estate projects by the developers of the country. One possible solution to reduce this economic barrier is the identification of aspects that add sustainability to the residential projects and cost the same or less than similar conventional real estate. The objective of this work is to identify the requirements of Aqua certification process (2013, version 2), which did not add additional costs to the referential residential development Reserva Anauá, being built for families with income between 6 and 10 minimum wages, and can be replicated in other projects with similar typology. Thus, entrepreneurs can incorporate up to 193 requirements of this certification to their residential projects, to make them more sustainable, without adding additional costs over conventional developments.

During the evaluation of the seismic retrofitting option for risk reduction/mitigation measures to be applied over buildings, Benefit Cost Analysis is an often-used method. During this study of Benefit Cost Analysis, the condition that the earthquake can happen just after or sometime after retrofitting will be taken into consideration rather than some approaches that focus on the benefits and costs regarding the annual probability of the occurrence for possible earthquakes. The analysis will use conditional probability such that the earthquake will be assumed to occur at different periods of time (5, 10, 20 years etc.) after the mitigation measures are taken so that benefit-cost ratios and net social benefits can be observed over time using the results at these periods. Also during this study the indirect effects of earthquake such as business disruption, social disturbance will also be taken into consideration. As a final step, it is aimed to conclude with convincing financial results regarding the direct and indirect effects of the earthquake in terms of benefits and costs to encourage people and the public officials to reduce the potential vulnerability of the housing units people live by taking the necessary precautions against the earthquake.

Today there is a global growing discourse regarding sustainability and the need for ecological responsibility. This in combination with the high level of shortage of accommodation on the market in Sweden and Stockholm, which is the geographically limitation of this study. One strategy to handle the shortage of accommodation and the high vacancy levels is property development through conversion where the change of use is in focus. This study is an exploratory study were the aim is to investigate how the existing property portfolio can be used to benefit the aspects of sustainability by conversion and a circular economic business model. There is also a goal to deepen the understanding of the incentives and market strategies in relation to conversion. The chosen method for this research is to use an abductive research method to ascertain the possibility for changes along projects’ life-time. Qualitative data have been collected with semistructured interviews as the main source where the respondents have been projects managers, and other essential actors, on a few selected companies as well as influential actors within the real estate sector. The three dimensions of sustainability, ecological, social and economic, have different influential roles depending on which explaining model that are studied. Also, there could be a ‘fourth dimension’ of sustainability, the cultural dimension, which widens the perspective. Further, the need for an environmental change have led to the birth of another economic model; circular economy. Here the traditional linear economic model is challenged with a model where recycling together with re-usage are in focus. Conversion is a strategy that is more frequently used now then for example 20 years ago, but the concept could have a larger role in today’s society. This could be seen as a circular economic approach for the construction, and/or real estate, industry, in which there have been investigations whether this new economic business model could have a bright future. Although, the actors on today’s market do believe that the traditional linear economic model is a better fit since it provides them with a larger profit in a shorter amount of time. Furthermore, the actors do believe that a circular economic business model is a good approach, but it is unfortunately not economically defendable in a large scale today. Since the market is full of uncertainties there are few actors that are willing to step into the world of conversion.Diskussionen gällande hållbarhet och ett ekologiskt ansvar är idag ett stort globalt samtalsämne. Detta i kombination med den stora bostadsbristen som råder i Sverige och i Stockholm, för vilken är den geografiska avgränsningen i denna studie. En strategi för att lösa bostadsbristen och höga vakansnivåer är med hjälp av fastighetsutveckling genom konvertering där ändrande av användningsområde står i fokus. Denna studie är utforskande med syftet att undersöka hur det går att använda sig av det befintliga fastighetsbeståndet för att gynna hållbarhetsaspekterna med hjälp av konvertering och en cirkulärekonomisk affärsmodell. Målet är också att få en djupare förståelse för incitamenten och marknadsstrategier i relation till konvertering. Vi har valt att använda en abduktiv undersökningsmetod. Kvalitativ data har samlats genom semistrukturerade intervjuer som huvudkälla där respondenterna har varit projektledare, och andra viktiga aktörer, på diverse utvalda företag såväl som inflytelserika aktörer inom fastighetsbranschen. De tre hålbarhetsdimensionerna, ekologiska, sociala och ekonomiska, har olika inflytelserika roller beroende på vilken förklarande modell som studeras. Det skulle också kunna finnas en fjärde hållbarhetsdimension, den kulturella dimensionen, som breddar perspektivet. Vidare så har behovet för en miljömässig förändring lett till skapandet av en annan ekonomisk modell; cirkulärekonomi. Här utmanas den traditionella linjärekonomiska modellen av en modell där återvinning och återanvändning står i fokus. Konvertering är en strategi som allt mer frekvent används idag än för exempelvis 20 år sedan, men detta koncept skulle kunna ha en ännu större roll i dagens samhälle. Detta skulle kunna ses som ett cirkulärekonomiskt tillvägagångssätt för bygg- och/eller fastighetsbranschen där det funnits undersökningar gällande om denna nya ekonomiska affärsmodell skulle kunna ha en ljus framtid till mötes. Dock tror dagens aktörer på marknaden att den traditionella linjärekonomiska modellen passar dem bättre då den är mer ekonomiskt lönsam på en kortare tid. Vidare tycker dessa aktörer att den cirkulärekonomiska affärsmodellen är ett bra tillvägagångssätt men att den tyvärr inte är ekonomiskt försvarbar i en större utsträckning idag. Eftersom marknaden är full av osäkerhet finns det enbart få aktörer som är villiga att ta klivet in i konverteringsvärlden.

As the third largest energy consumer, the residential sector in Canada is responsible for 17% of energy consumption and 15% of greenhouse gas emissions. With the increase in population, the number of new houses is expected to increase by 2.8 million from 2005 to 2020, and more energy is expected to be consumed despite the emergence of better insulated houses and more efficient heating methods. The primary objective of this study is to determine the prospects of reducing CO2 emissions from the residential sector in Waterloo Region by achieving a higher building standard, such as the Passivhaus (PH) and Net Zero Energy (NZE). The profile of the building envelope, including the initial CO2 emissions was compared against the requirements of the PH and NZE standards, using the Residential Energy Efficiency Project dataset (2007-2012). The second objective evaluates the barriers and drivers that influence the setting of higher building envelope standards. Ontario Building Codes (1975-2012) were analysed to determine the changes to insulation requirements over time, and Ontario Legislative Assembly debates (1970-2012) were reviewed to determine the barriers and drivers expressed in political debates. Content analysis was applied to the Legislative Assembly of Ontario’s documents to determine the frequency of nine word categories prior to each new building code. This study identified three main categories of drivers: awareness of environmental issues, resource limitation, and the implications of climate change; and three categories of barriers: financial, political and structural, and barriers related to information, promotion, and education. The findings of this study confirm that existing houses in Waterloo Region can achieve substantial reductions in CO2 emissions and energy usage by meeting higher building standards. Building code improvements have certainly played an important role in the evolution of Ontario houses, and the 2012 building code, achieves the R-2000 standard universally. More advanced standards show the potential for greater savings, but have only been adopted on a voluntary basis.

The casualties and economic loss related to private buildings due to the earthquake in Meinong District in Kaohsiung in 2016 reflected the importance of seismic retrofitting projects in such buildings. Under the restrictions of current rules, regulations, and systems, the government has promoted projects for the seismic assessment and retrofitting of structures in the hope of utilizing available resources to encourage people to conduct related evaluation and modification. In 2017, an act to expedite the reconstruction of old and dangerous urban buildings passed all required legislative stages and came into effect, serving as a basis for rules, regulations, and systems related to the demolition and reconstruction of private buildings with structural hazards. However, no law for retrofitting private buildings with structural hazards has been drafted and related design practices and supportive mechanisms are scarce. Therefore, in order to explore the necessity and urgency of the relevant regulations and promotion strategies for seismic assessment and retrofitting of building, and to assist the establishment of the relevant regulations and the promotion mechanism of seismic retrofitting of private building. Pushover analysis on historical building cases was simulated using structural analysis software. Earthquake damage in metropolitan areas was assessed, and the input–output approach to cost–benefit analysis of seismic retrofitting was employed. In addition, software was adopted to simulate cases of seismic retrofitting in buildings, with the Taiwan Earthquake Loss Estimation System developed by the National Center for Research on Earthquake Engineering employed to conduct cost analysis on building retrofitting. The cost analysis results of two buildings in this study were compared to the actual costs incurred by building damage due to the earthquake to complete the cost–benefit analysis of the retrofitting projects. Based on former research results, this investigation verifies the relevant regulations and promotion mechanism for seismic assessment and retrofitting of existing buildings. Furthermore, this work also measures the benefits of the simulation for seismic assessment and retrofitting to promote the inspection and repair related tasks of private buildings in domestic area.

The amount of energy consumption in the residential buildings has a very significant share with nearly 30 percent in the total amount of energy consumption. Therefore, residential sector is identified in this chapter as being one of the areas with a large potential for energy savings. Inefficient dwelling construction and design methods are widely used in Turkey and only about five percent of residential buildings are insulated. Concerning the importance and immediate need in Turkey for energy-efficient residential building retrofitting, this chapter identifies economic benefits of such retrofitting by particularly focusing on heat transfers by conductivity, where the rate can be determined by surface size, thermal resistance of the building materials and their thickness.

The main financial barrier of large scale implementation of green building retrofitting investments is due to the relatively large investment volume needed, compared to the future flow of yearly energy savings or/and yearly estimated differences of incomes collected, if the building is a commercial building (commercial center, office building, hotel or even residential rental building). The uncertainty implicitly involved in this estimation, both for the future savings and for the yearly differences of incomes, which are usually not very large, both make these investments apparently not so attractive for private investors, especially for owners of residential buildings, with limited self-financing power. Nevertheless, from the society point of view, the benefits created by saving the energy and consequently reducing the carbon foot print, can be very attractive. That is why the public support is often used as an “impulse solution” for implementation of these investments. The Cost Benefit Analysis methodology, particularized for these investments, is presented in this chapter.

This chapter is a case study for the energy retrofit of an existing single-family residential building. The main assumption of the project was creating a model example for an energy retrofit with the aim of achieving the nZEB standard in existing residential building. The discussed building was built between the 1960s and the 1970s. The building was built using mixed technologies. The flooring on the ground floor was replaced; the foundation, external walls, and roof were thermally insulated. The windows and doors were replaced with higher parameter ones. Moreover, a modern biomass boiler was installed in the building along with the installation of a mechanical bidirectional ventilation unit with a heat recovery. Before the renovation, the building used about 133.4 GJ final energy for heating annually. After the renovation, the building uses about 8.89 GJ annually. The author describes all the stages of the renovation, the technical solutions, the calculations of economic and environmental benefits of the conducted renovations.

The reduction of anthropogenic green house gas emissions through increased building energy efficiency is a global effort, which is a responsibility of both developed and developing nations. The Passive House concept is a building design methodology that advocates for a systematic optimization and integration of the building envelope and internal loads in order to achieve a passive yet comfortable performance. Multiple passive houses have been built and monitored in Europe and the United States. The present paper attempts to determine what design features are required for tropical residential buildings to meet the Passive House Standard. This study was conducted in El Salvador, which experiences a warm and humid climate throughout the year. For economic and cultural reasons, few residential buildings in the country have air conditioning systems. However, the vast majority of residential buildings have not been designed using passive principles, causing great occupant discomfort and increasing energy consumption for cooling. Both the Passive House Planning Package (PHPP) software and EnergyPlus were used in order to determine the design parameters that would yield a passive house for this climate. In addition, the paper discusses the technical and economic feasibility of modifying a typical house to meet the standard. The potential benefits related to occupant comfort and energy cost savings are also discussed.

In this paper, a novel type of ground heat exchanger for geothermal applications is introduced. This heat exchanger is installed in the foundations of a commercial and residential building that has piles and diaphragm walls. This dramatically reduces the cost of the ground heat exchanger and makes the application more cost efficient with a payback period of 1–2 years compared to 10 years with the conventional vertical loops. The system will be detailed and its basic operation will be explained. In addition, test results of an in-situ thermal test response of a loop that is already installed in a foundation of a building in Beirut, Lebanon will also be presented. This test allows the approximation of the thermal conductivity of the ground and the amount of heat that is absorbed and extracted from and to the ground. The preliminary tests have given very promising results, since the ground is water dense and has a high thermal conductivity which increases the heat transfer between our heat exchanger installed in the foundation and the ground. In addition, in the current application, and around the foundation, there exists a lot of circulating water. This renders the application more and more efficient since the ground temperature will not fluctuate in the next 10 years.

Currently, the construction sector is facing requirements for higher quality and efficiency standards as well as objectives related to value creation. In construction, rational decision-making problems often involve creating a unique complex of criteria, which must consider multiple requirements and conditions. The paper presents the developed model for the selection of multi-layered external walls of a residential building. The model considers the following aspects and parameters: time, cost, quality, environmental conditions, aspects of sustainable development, and problemsolving benefits received from the assessment of alternatives and the development of the model. Game theory was used to calculate the defining rational decision. For the calculations was used game theory: Bayes, Wald’s rule, Savage criterion, Laplace’s rule. This study presents the developed model for the selection of multi-layered external walls of a residential building and calculation results based on game-theory rules, which are effective tools for rational decisionmaking.

Residential buildings account for a large portion of total energy consumption in the United States. Residential energy usage can be dramatically reduced by improving the efficiency of building envelope systems. One such method is to incorporate thermally massive construction materials into the building envelope. This benefits building operation by reducing the energy requirement for maintaining thermal comfort, downsizing the AC/heating equipment, and shifting the peak load from the electrical grid. When impregnated or encapsulated into wallboard or concrete systems, phase change materials (PCMs) can greatly enhance their thermal energy storage capacity and effective thermal mass. In this work we numerically study the potential of PCM on energy saving for residential homes. For that purpose we solve the one-dimensional, transient heat equation through the multi-layered building envelope using the Crank-Nicolson discretization scheme. The latent heat storage of the PCM was accounted for with a phase fraction in a latent heat source term. Using this code we examine a PCM composite wallboard incorporated into the walls and roof of a typical residential building across various climate zones. The PCM performance was studied under all seasonal conditions using the latest typical meteorological year (TMY3) data for exterior boundary conditions. Comparisons were made between different PCM wallboard locations. Our work shows that there is an optimized location for PCM placement within building envelope surfaces dependent upon the resistance values between the PCM layer and the exterior boundary conditions. We further identified the energy savings potential by comparing the performance of the PCM wallboard against the performance of a building envelope without PCM. Our study shows that PCM composite wallboard can reduce the energy consumption in summer and winter and can shift the peak electricity load in the summer.

The use of Prismatic Skylights and its effects as a passive Energy Conservation Strategy in “Residential” and “Big Box Commercial Buildings” in hot and humid climate has been evaluated throughout this project. The potential benefits of using skylights reside in the fact that it reduces electrical lighting necessities but at the same time it contributes to an upsurge of the Cooling Loads of the conditioned space. Acknowledging the impact of skylights is fundamental to elaborate an optimized design of a building’s energy efficient mechanical system. To reach a sound conclusion, the evaluated buildings were modeled and their performance was simulated using the Department of Energy Simulation Program “Energy Plus”. To be able to compare the Energy Conservation Measure case (Using Skylights) with the Base Line (No Skylights), a photometric sensor was modeled to ensure that both cases sourced the same amount of light visible in the electromagnetic spectrum. Considering the Heating, Cooling and lighting energy consumption as variables, the variance between the ECM and the Base line for the residential case was 5% more energy consumption with skylights. For the Big Box Commercial Building there was a 5% deduction in energy consumption in the ECM case using 5% roof area covered with skylights. The results obtained from this investigation reveal a very promising effect in the implementation of skylights in “Big Box Commercial Buildings”, but not so optimistic in the case of “Residential Buildings” for hot and humid climate as shown by the simulation and monitoring data from the experimental case.

The actual growing world energy demand is generating strong attention to the energy efficiency and to the environmental sustainability. The residential sector is one of the most energy-intensive reaching about 25% of global energy consumption. Furthermore, it is difficult to understand the real energy use in residential buildings suggesting the development of methodologies and tools to monitor and assess their energy performances. Such an analysis requires defining all the actors, their interaction rules and the intelligent management of a large amount of data. In addition to this, the energy performances of the home environment are closely related to the specific case under investigation, in fact it imposes the analysis of the particular application scenario and the target users to extract parameters able to describe the building behavior. They are related to the technological characteristics of the systems, to the external environment (e.g. external temperature, solar irradiation, etc.) and to the user needs and habits. It introduces some complexities, because many of these data are difficult to find and to predict. Another cause of complexity was introduced by the information and communication technologies (ICT) that creates new relationship between home devices fostering the spread of smart systems. In this scenario, simulation tools have been developed to grasp the real energy performance of a building, but they require a high level of detail for the input data which are often difficult to find. Otherwise, other tools are built for much simplified simulations and typically addressed to inexperienced users neglecting the real complexities of the system. For this reason, the paper presents a new design approach that aims to develop knowledge-based tools with architecture able to simulate the real behavior of the building considering all the actors and their interaction rules, but at the same time containing the features that allow them to be used in fast simulations or by inexperienced users. One of the focuses is the development of an intelligent user interface that, when requested, is able to automate and simplify data entry process. It is particularly useful when the user does not know the necessary input data for the simulation, e.g. energy consumption profiles, detailed features of the building, etc. All the steps of the proposed approach are described in the paper. In the first section is highlighted how the key parameters have been found and how they are organized as creating a knowledge base, while in the second section is shown the operation of the smart user interface and of the simulation tool. The results demonstrate that the proposed knowledge-based approach generates real benefits by simplifying and speeding up the data entry. Furthermore, the study shows how the smart user interface allows performing complex simulations also to novice users.

Abstract In this report, a resiliency analysis is carried out to assess the energy, economic, and power outage survivability benefits of efficient and Net-Zero communities. The analysis addresses the appropriate steps to designing an energy-efficient and Net-Zero community using Phoenix, Arizona as a primary location for weather and utility inputs. A baseline home is established using International Energy Conservation Code (IECC) 2018 code requirements. Three occupancy levels are evaluated in BEopt to provide diversity in the community’s building stock. The loads from the baseline, energy-efficient optimum, and Net-Zero optimum single-family homes are utilized to determine energy use profiles for various residential community types using occupancy statistics for Phoenix. Then, REopt is used to determine the photovoltaic (PV) and battery storage system sizes necessary for the community to survive a 72-hour power outage. The baseline community requires a 544-kW PV system and 375-kW/1,564 kWh battery storage system to keep all electrical loads online during a 72-hour power outage. The energy-efficient community requires a 291-kW PV system and a 202-kW/820 kWh battery storage system while the Net-Zero community requires a 291-kW PV system and a 191-kW/880 kWh battery storage system. In this study, the economic analysis indicates that it is 43% more cost-effective to install a shared PV plus storage system than to install individual PV plus storage systems in an energy-efficient community. After analyzing the system sizes and costs required to survive various outage durations, it is found that only a 4% difference in net present cost exists between a system sized for a 24-hour outage and a 144-hour outage. In the event of a pandemic or an event that causes a community-wide lockdown, the energy-efficient community would only survive 6 hours out of a 72-hour power outage during a time where plug loads are increased by 50% due to added laptops, monitors, and other office electronics. Finally, a climate sensitivity analysis is conducted for efficient communities in Naperville, Illinois and Augusta, Maine. The analysis suggests that for a 72-hour power outage starting on the peak demand day and time of the year, the cost of resiliency is higher in climates with more heating and cooling needs as HVAC is consistently the largest load in a residential building.

The increasing demands for housing the burgeoning urban population in developing countries like India has impelled the need to shift to mechanised construction practices like Precast Concrete Construction (PCCon) for faster supply of projects. PCCon has been successfully implemented in developed countries to meet the once prevalent housing shortages and is still being adopted extensively in high rise residential building projects in these countries. PCCon offers several benefits compared to cast in situ construction practices such as reduced construction time, time and cost certainty, improved quality control and improved health and safety. PCCon also promotes environment friendly construction, addresses shortage of skills and results in minimisation of life cycle costs.
