Abstract:

A zero-energy building, also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), or net zero building, is a building with zero net energy consumption and zero carbon emissions annually. Buildings that produce a surplus of energy over the year may be called “energy-plus buildings” and buildings that consume slightly more energy than they produce are called “near-zero energy buildings” or “ultra-low energy houses”. Traditional buildings consume 40% of the total fossil fuel energy in the US and European Union and are significant contributors of greenhouse gases. The zero net energy consumption principle is viewed as a means to reduce carbon emissions and reduce dependence on fossil fuels and although zero energy buildings remain uncommon even in developed countries, they are gaining importance and popularity.

Abstract:

This study has analysed which options would be appropriate to use as additional requirements to the main requirement of primary energy number in the new Swedish building regulations. The starting point is to ensure that buildings are built with good qualitative properties in terms of the building envelope so that low energy use can be maintained throughout the life of the building despite changes in installation systems or the building’s occupancy. The additional requirements should aim to minimize energy losses, i.e., to ensure that the building's total energy demand is low. The following possible additional requirements have been examined: net energy demand, net energy demand for heating, heat power demand, heat loss rate and average heat transfer coefficient. In order to ensure that the additional requirements will work as desired and to explore possibilities with, and identify the consequences of, the various proposals, calculations have been made for four different categories of buildings: single-family houses, apartment buildings, schools and offices. The results show that the suggested option net energy demand will not contribute to any additional benefits in relation to primary energy number. The other options analysed have both advantages and disadvantages and it is difficult to find a single additional requirement that fulfils all the pre-set demands.

Abstract:

Net Zero-Energy Buildings (NZEBs) have received increased attention in recent years as a result of constant concerns about energy supply constraints, decreasing energy resources, increasing energy costs and the rising impact of greenhouse gases on world climate. Promoting whole building strategies that employ passive measures together with energy efficient systems and technologies using renewable energy became a European political strategy following the publication of the Energy Performance of Buildings Directive recast in May 2010 by the European Parliament and Council. However designing successful NZEBs represents a challenge because the definitions are somewhat generic while assessment methods and monitoring approaches remain under development and the literature is relatively scarce about the best sets of solutions for different typologies and climates likely to deliver an actual and reliable performance in terms of energy balance (consumed vs generated) on a cost-effective basis. Additionally the lessons learned from existing NZEB examples are relatively scarce. The authors of this paper, who are participants in the IEA SHC Task 40-ECBCS Annex 52, “Towards Net Zero Energy Solar Buildings”, are willing to share insights from on-going research work on some best practice leading NZEB residential buildings. Although there is no standard approach for designing a Net Zero-Energy Building (there are many different possible combinations of passive and efficient active measures, utility equipment and on-site energy generation technologies able to achieve the net-zero energy performance), a close examination of the chosen strategies and the relative performance indicators of the selected case studies reveal that it is possible to achieve zero-energy performance using well known strategies adjusted so as to balance climate driven-demand for space heating/cooling, lighting, ventilation and other energy uses with climate-driven supply from renewable energy resources.

Abstract:

The building sector is responsible for 39% of process-related greenhouse gas emissions globally, making net- or nearly-zero energy buildings pivotal for reaching climate neutrality. This article reviews recent advances in key options and strategies for converting the building sector to be climate neutral. The evidence from the literature shows it is possible to achieve net- or nearly-zero energy building outcomes across the world in most building types and climates with systems, technologies, and skills that already exist, and at costs that are in the range of conventional buildings. Maximizing energy efficiency for all building energy uses is found as central to net-zero targets. Jurisdictions all over the world, including Brussels, New York, Vancouver, and Tyrol, have innovated visionary policies to catalyze themarket success of such buildings, with more than 7 million square meters of nearly-zero energy buildings erected in China alone in the past few years. Since embodied carbon in building materials can consume up to a half of the remaining 1.5°C carbon budget, this article reviews recent advances to minimize embodied energy and store carbon in building materials.

Abstract:

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.

Abstract:

Residential and commercial buildings consume approximately 60% of the world’s electricity. It is almost impossible to provide a general definition of thermal comfort, because the feeling of thermal comfort is affected by varying preferences and specific traits of the population living in different climate zones. Considering that no studies have been conducted on thermal satisfaction of net-zero energy buildings prior to this date, one of the objectives of the present study is to draw a comparison between the thermal parameters for evaluation of thermal comfort of a net-zero energy building occupants. In so doing, the given building for this study is first optimized for the target parameters of thermal comfort and energy consumption, and, hence, a net-zero energy building is formed. Subsequent to obtaining the acceptable thermal comfort range, the computational analyses required to determine the temperature for thermal comfort are carried out using the Computational Fluid Dynamics (CFD) model. The findings of this study demonstrate that to reach net-zero energy buildings, solar energy alone is not able to supply the energy consumption of buildings and other types of energy should also be used. Furthermore, it is observed that optimum thermal comfort is achieved in moderate seasons.

Abstract:

The objective of this research is to study the cost of Net Zero Energy (NZE) communities of different urban scales and densities, while taking into consideration the local climate and the type of buildings in the community. A comprehensive model was developed for this purpose, with which the cost-optimal configuration of renewable energy-related technologies for an NZE community can be identified. To validate the model, data from two case studies that differed in their climate and building types were used. The results of this study contribute to a better understanding of the implications of NZE requirements for urban planning. An increase in the scale of a community was found to reduce energy costs, up to a certain point. Urban density, on the other hand, was found to have a more complex impact on costs, which depends on the local climate of the community and the subsequent energy demand. This underlines the importance of addressing the technological design of energy systems at the initial stage of the urban planning of energy-efficient communities, before the urban density, the unbuilt areas and the building types are set.

Abstract:

“Net Zero-Energy Building” has become a popular catchphrase to describe the synergy between energy-efficient building and renewable energy utilisation to achieve a balanced energy budget over an annual cycle. Taking into account the energy exchange with a grid overcomes the limitations of energy-autonomous buildings with the need for seasonal energy storage on-site. Although the expression, “Net Zero-Energy Building,” appears in many energy policy documents, a harmonised definition or a standardised balancing method is still lacking. This paper reports on the background and the various effects influencing the energy balance approach. After discussing the national energy code framework in Germany, a harmonised terminology and balancing procedure is proposed. The procedure takes not only the energy balance but also energy efficiency and load matching into account.

Abstract:

The UKGBC Net Zero Carbon Buildings Framework was published in April 2019 following an industry task group and extensive consultation process. The framework acts as guidance for achieving net zero carbon for operational energy and construction emissions, with a whole life carbon approach to be developed in the future. In consultation with industry, further detail and stricter requirements are being developed over time. In October 2019, proposals were set out for industry consultation on minimum energy efficiency targets for new and existing commercial office buildings seeking to achieve net zero carbon status for operational energy today, based on the performance levels that all buildings will be required to achieve by 2050. This was complemented by modelling work undertaken by the LETI network looking into net zero carbon requirements for new buildings. In January 2020 UKGBC published its guidance on the levels of energy performance that offices should target to achieve net zero and a trajectory for getting there by 2035. This paper describes the methodology behind and industry perspectives on UKGBC’s proposals which aim to predict the reduction in building energy intensity required if the UK’s economy is to be fully-powered by zero carbon energy in 2050. Practical application: Many developers and investors seeking to procure new commercial offices or undertake major refurbishments of existing offices are engaging with the ‘net zero carbon’ agenda, now intrinsic to the legislative framework for economic activity in the UK. A UKGBC initiative effectively filled a vacuum by defining a set of requirements including energy efficiency thresholds for commercial offices in the UK to be considered ‘net zero carbon’. This paper provides all stakeholders with a detailed justification for the level of these thresholds and what might be done to achieve them. A worked example details one possible solution for a new office.

Abstract:

This article focuses on the research and development projects to ensure homes and office buildings implement the concept of zero net energy, i.e. self-sufficient in energy buildings. Net-zero commercial construction has doubled since 2008. Reducing energy consumption on the inside depends on ultra-efficient appliances, high-performance heating, ventilation, and air conditioning (HVAC) systems, geothermal heat pumps, and lighting controls. Impressive advances are occurring in the field of solid-state lighting technology, which has the potential to reduce U.S. lighting energy usage by nearly 50%. The solar-energy technology company Vivint partnered with Garbett Homes to take on one of the biggest challenges for net-zero housing: creating designs that work in cold climates. The house that Vivint and Garbett built in Herriman, Utah, attained a Home Energy Rating System score of zero, indicating that the home is completely self-sustaining. The Habitat for Humanity house, in particular, shows how affordable zero net energy homes can be – especially for lower income homeowners.

Abstract:

With buildings around the world accounting for nearly one-third of global energy demand and the availability of fossil fuels constantly on the decline, there is a need to ensure that this energy demand is efficiently and effectively managed using renewable energy now more than ever. Most research and case studies have focused on energy efficiency of ‘new’ buildings. In this study, both technical and financial viability of Net Zero Energy Buildings (NZEB) for ‘existing’ buildings will be highlighted. A rigorous review of open literatures concerning seven principal areas that in themselves define the concept of NZEB building is carried out. In practice, a suitable option of the NZEB solutions is needed for the evaluation and improvement for a specific geographical area. The evaluation and improvement has been carried out using a novel hierarchy-flow chart coupled with a Building Information Model (BIM). This BIM or digital twin is then used to thoroughly visualize each option, promote collaboration among stakeholders, and accurately estimate associated costs and associated technical issues encountered with producing an NZEB in a pre-determined location. This paper also provides a future model for NZEB applications in existing buildings, which applies renewable technologies to the building by aiming to identify ultimate benefit of the building especially in terms of effectiveness and efficiency in energy consumption. It is revealed that the digital twin is proven to be feasible for all renewable technologies applied on the NZEB buildings. Based on the case study in the UK, it can be affirmed that the suitable NZEB solution for an existing building can achieve the 23 year return period.

Abstract:

The potential of carbon dioxide emissions mitigation in the building sector can be achieved through energy policies, progressive goals, and support systems to attain sustainable constructions that guarantee the reduction of emissions. Net-Zero Energy Buildings (NZEB) is a concept that allows moving forward to neutralize buildings’ carbon emissions. This has been demonstrated by more industrial countries which have set goals and challenges to progressively approach an energy neutrality balance for buildings. Therefore, the target of this research is to define a framework for a new standard to reach NZEB in Chile. Firstly, an exhaustive review of the energy policies, NZEB definitions, and components of an NZEB system took place. Secondly, focus group discussions with local and international professionals from the building sector were organized to define a vision, opportunities, and potential measures with a focus on policies, to implement and develop local technologies for NZEB buildings in Chile. The study identifies the need to advance public policies to achieve an integrated policy for the implementation of energy neutral concept buildings. Finally, the paper presents a NZEB standard framework, including key performance indicators and suggested performance metrics thresholds.

This paper addresses the concept of net zero energy and net metering in efficient buildings in order to assist in the study and development of future microgrids for buildings with annual zero energy consumption. There are several definitions for zero energy buildings available in the literature with a distinct set of project goals and interests, but this work is focused on the definition that accounts for energy losses by converting each energy type to source energy. Finally, a case study is presented to evaluate whether four distinct all-electric buildings can achieve annual zero energy by deploying on-site renewable sources within their site boundary.

Abstract:

1.0. INTRODUCTION In the United States, K–12 school buildings spend more than $8 billion each year on energy—more than they spend on computers and textbooks combined [1]. Most occupied older buildings demonstrate poor operational performance—for instance, more than 30 percent of schools were built before 1960, and 53 percent of public schools need to spend money on repairs, renovations, and modernization to ensure that the schools' onsite buildings are in good overall condition. And among public schools with permanent buildings, the environmental factors in the permanent buildings have been rated as unsatisfactory or very unsatisfactory in 5 to 17 percent of them [2]. Indoor environment quality (IEQ) is one of the core issues addressed in the majority of sustainable building certification and design guidelines. Children spend a significant amount of time indoors in a school environment. And poor IEA can lead to sickness and absenteeism from school and eventually cause a decrease in student performance [3]. Different building types and their IEQ characteristics can be partly attributed to building age and construction materials. [4] Improving the energy performance of school buildings could result in the direct benefit of reduced utility costs and improving the indoor quality could improve the students' learning environment. Research also suggests that aging school facilities and inefficient equipment have a detrimental effect on academic performance that can be reversed when schools are upgraded. [5] Several studies have linked better lighting, thermal comfort, and air quality to higher test scores. [6, 7, 8] Another benefit of improving the energy efficiency of education buildings is the potential increase in market value through recognition of green building practice and labeling, such as that of a LEED or net zero energy building. In addition, because of their educational function, high-performance or energy-efficient buildings are particularly valuable for institution clients and local government. More and more high-performance buildings, net zero energy buildings, and positive energy buildings serve as living laboratories for educational purposes. Currently, educational/institutional buildings represent the largest portion of NZE (net zero energy) projects. Educational buildings comprise 36 percent of net zero buildings according to a 2014 National New Building Institute report. Of the 58 net zero energy educational buildings, 32 are used for kindergarten through grade 12 (K–12), 21 for higher education, and 5 for general education. [9] Finally, because educational buildings account for the third largest amount of building floor space in the United States, super energy-efficient educational buildings could provide other societal and economic benefits beyond the direct energy cost savings for three reasons: 1) educational buildings offer high visibility that can influence community members and the next generation of citizens, 2) success stories of the use of public funds that returns lower operating costs and healthier student learning environments provide documentation that can be used by others, and 3) this sector offers national and regional forums and associations to facilitate the transfer of best design and operational practices.

Abstract:

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.

Abstract:

In the face of extreme climate, Net Zero Energy Buildings (NZEBs) represent a very high standard of building energy conservation. The design of NZEBs requires continuous design improvement and analysis in a decision-making process that seeks to meet energy conservation goals. This paper recommends the use of green Building Information Modelling (BIM) to support the design of zero-energy buildings. The design of NZEBs requires two sets of tasks: First, it requires determination of whether the building will offer high-energy efficiency, and, second, it lacks the installation of sufficient renewable energy equipment to meet the building’s load needs. After drawing on the spirit of the United States’ Leadership in Energy and Environmental Design and considering the current situation in Taiwan, this paper recommends the use of electricity Energy Usage Intensity as a measurement unit providing a holistic indicator of energy usage and takes optimized energy performance as a performance target for various solutions. This study demonstrated procedural steps in the application of green BIM and analyzed restrictions on the implementation of green BIM to the analysis of NZEB design.

Abstract:

The connotations and denotations of the term net-zero-energy solar buildings (NZESBs) have been in constant flux because of continuous developments in solar heating technology, solar photovoltaic (PV) technology, building energy-storage technology, regional energy-storage technology, and energy-management systems. This paper focuses on innovative strategies for implementing NZESBs in Nanjing, China. These strategies include integrated architectural design, including passive solar design (respecting climatic characteristics and conducting integrated planning based on the environment, building orientation, distance between buildings, building shape, ratio of window area to wall area, and building envelope) and active solar design (integration of the solar-energy-collecting end of the system – collectors and PV panels – with the building surface – roof, wall surfaces, balconies, and sun-shading devices – and the integration of solar-energy transfer and storage equipment with the building). Some Nanjing-specific recommendations and findings on NZESBs are proposed. The results illustrate that NZESBs can be realized in Nanjing if solar energy technologies are appropriately integrated with the characteristics of Nanjing's geography, climate and buildings.

Abstract:

ZEBs (zero energy buildings) and more specifically “net Zero Energy Building” (nZEB) have become a prominent wording to describe the synergy of energy efficient building and renewable energy utilization to reach a balanced energy budget over a yearly cycle. The lack of a common and accepted definition or even a good understanding of ZEB makes the approach of this problem very challenging. In this paper there is an evaluation of the criteria in the definition framework and selection of the related options. Also a methodology is approached, to set nZEB definitions in a systematic way. Today's different ZEB technologies, challenges and problems are identified and analyzed. For the first time the overall operation of nZEB and its performance is investigated and modeled using FCMs and learning algorithms. A set of low energy buildings using extensive energy and environmental data are simulated for all four seasons of a year. Interesting results are obtained, presented and discussed. Useful conclusions are drown and future research challenging topics are presented.

Abstract:

Buildings in Canada account for a significant amount of greenhouse gas (GHG) emissions and net zero energy building technology has been identified as part of the solution. This study presents a conceptual model identifying barriers to the adoption of net zero energy housing and tests it by administering a survey to 271 participants in a net zero energy housing demonstration project in Toronto, Canada. Using multivariate correlation and multi-linear regression analyses this study finds that of all the innovation adoption variables it was the construction and design quality that was the most significant contributor to the adoption of a net zero energy home by a potential home owner. This study found that the (a) extra cost compared to a conventional home, b) lack of knowledge about the technology associated with a net zero energy home or (c) not knowing someone who owned a net zero energy home were not significant barriers to accepting net zero energy homes. Our results suggest that policy-makers should promote the diffusion of net zero energy home technology by encouraging housing developers to include net zero energy homes in their collection of model homes, with an emphasis on quality design and construction. Furthermore, engaging in trust building initiatives such as education and knowledge about the technology, its related energy cost savings, and the environmental benefits would contribute to a greater acceptance of net zero energy homes.

Abstract:

Nowadays, net-zero energy buildings (NZEBs) concept has gained considerable attention not only between the developed countries, but also among the developing countries including Malaysia. The rapid development in Malaysia, especially in the construction of healthcare buildings needs to be given due attention since these developments lead to all sorts of environmental problems. As the number of healthcare buildings increases, the energy consumes to operate these buildings will increase. The consequences of uncontrollable energy consumption may result in the increased volume of carbon dioxide emissions as well as depletion of natural resources. Thus, NZEBs has emerged as a proactive concept to confront with these issues. Therefore, the purpose of this paper is to examine the influence of passive design approaches on NZEBs as well as the potential of net zero healthcare buildings implementation in Malaysia based on a review of the existing literature and by utilising semi-structured interviews with 3 experienced architects. The result of this paper indicates that there are four main passive design components has strong influences on NZEBs which are building orientation, shading devices, ventilation, and thermal insulation. These practices are being actively practiced in Malaysia construction industry; thus, it shows that net zero energy healthcare buildings are potential to be designed in Malaysia. The study has gone some way towards enhancing our understanding of the significance of passive design approaches towards net zero healthcare buildings for future implementation in Malaysia context.

Abstract:

This research introduces a residential net-zero energy house named i-Yard 2.0, which was built by a team from Beijing Jiaotong University for the 2018 Solar Decathlon China competition. The concept was based on the needs of an aging population and achieves energy self-sufficiency through both active (i.e., solar energy) and passive design strategies. With the growing recognition of the need for better environmental protection, green building strategies have become mainstream in building development. A building’s energy balance is one of the most important indexes for assessing green buildings. The i-Yard 2.0 adopts an integrated design strategy with a sustainable development background. It takes a senior citizen-oriented design as the starting point and innovates in aspects such as community modeling, building strategies, passive spatial planning, the energy and building environment, and intelligent building control. The community comprises a new residential model called “cooperative living.” The building strategy adopts a modular assembly approach in order to achieve rapid construction suitable for this type of competition. The passive spatial plan uses the notion of the courtyard as a green core to regulate the microclimate. The building environment achieves net-zero energy by improving active energy access and reducing passive energy consumption. The internet control model was designed to incorporate intelligent building control. The i-Yard 2.0 provides not only a new form of senior residential housing for developing areas, it also provides a novel and worthy reference for net-zero energy housing in China.

Abstract:

In recent years, there have been a growing number of projects and initiatives to promote the development and market introduction of low and net-zero energy solar homes and communities. These projects integrate active solar technologies to highly efficient houses to achieve very low levels of net-energy consumption. Although a reduction in the energy use of residential buildings can be achieved by relatively simple individual measures, to achieve very high levels of energy savings on a cost effective basis requires the coherent application of several measures, which together optimise the performance of the complete building system. This article examines the design process used to achieve high levels of energy performance in residential buildings. It examines the current design processes for houses used in a number of international initiatives. The research explores how building designs are optimised within the current design processes and discusses how the application of computerised optimisation techniques would provide architects, home-builders, and engineers with a powerful design tool for low and net-zero energy solar buildings.

Abstract:

Net Zero Energy Building (Net ZEB) concept has been applied to make a selected building as a self-energy provider. The building was partly modified to reduce its energy consumption using several energy efficient technologies such as wall material, insulator, VRF air condition unit, solar lighting, LED light bulbs, etc. While, electricity served into the building was generated by solar energy (PV panels). The monitored data over one year have proved that this build can generate the electricity more than its energy demand. This is a good achievement of Net ZEB in Thailand.

Abstract:

Abstract The introduction of financial incentives for net-zero energy building/community (ZEB/ZEC) is a potential strategy that facilitates the development of sustainable buildings. In this study, a reward-penalty mechanism (RPM) is firstly proposed for a community that aims to achieve the target of annual zero energy balance. In order to investigate the cost allocated for each building in the community, a cost allocation model by considering the load of these buildings and the levels of zero energy building achieved is further proposed, based on which four typical types of the model is selected and investigated. The economic performance of a building under the four types of allocation model is then compared for a community that consists of 20 family houses in Ireland. By considering the possible ZEB level ranges in each building, two Cases are conducted (Case 1 – the range is between 0.0 and 1.0; Case 2 – the range is between 0.5 and 1.0). The results show that the 1st model is the simplest one that allocates cost evenly. By contrast, the cost of a building depends on its load in the 2nd model and depends on the ZEB level it achieved in the 3rd model, while it considers the two factors evenly in the 4th model. The proposed cost allocation model is expected to provide a basic guide for the designers of financial incentives as well as experts in the fields of net-zero energy buildings.

Abstract: Energy efficiency is a top priority in design, because design errors that result in wasteful energy will impact operational costs as long as the building operates. The opening protection in the facade should be adjusted according to their needs, for optimum use of sky light. Inhibiting the entry of solar heat into the room through the process of radiation, conduction or convection, optimum use of sky light and efforts to use building skin elements for shading are very wise efforts for energy savings. House construction planning must be careful and consider many things, including: physical potential. Physical potential is a consideration of building materials, geological conditions and local climate. Related to the issue of global warming that occurs in modern times, climate is a major consideration that needs to be resolved.The purpose of building design, especially in residential homes aims to create amenities for its inhabitants. Amenities are achieved through physical comfort, be it spatial comfort, thermal comfort, auditory comfort, or visual comfort.Energy waste is also caused by building designs that are not well integrated and even wrong and are not responsive to aspects of function, and climate. This is worsened by the tendency of the designers to prioritize aesthetic aspects (prevailing trends). The issue of green concepts and energy consumption efficiency through the Net Zero-Energy Buildings (NZE-Bs) program from the housing sector as a response to tackling global warming is already familiar in Indonesia, although its application has not yet been found significantly. Green concepts offered by housing developers are often merely marketing tricks and are not realized and grow the responsibility of the residents to look after them. Due to the lack of understanding of the green concept, housing developers tend to offer more a beautiful and green housing environment, not the actual green concept.Keyword: Socio-culture, Energy efficiency, Energy consumption, Environment.

Amenities dicapai melalui kenyamanan fisik, baik itu spatial comfort, thermal comfort, auditory comfort, maupun visual comfort.Pemborosan energi juga disebabkan oleh desain bangunan yang tidak terintegrasi dengan baik bahkan salah dan tidak tanggap terhadap aspek fungsi, serta iklim. Hal tersebut diperparah yang kecenderungan para perancang lebih mementingkan aspek estetis (tren yang berlaku). Isu konsep hijau dan efisiensi konsumsi energi melalui program Net Zero-Energy Buildings (NZE-Bs) dari sektor perumahan sebagai respon untuk menanggulangi pemanasan global sudah tidak asing di Indonesia, walaupun penerapannya masih belum dapat ditemukan secara signifikan. Konsep hijau yang ditawarkan oleh pengembang perumahan seringkali hanya sebagai trik pemasaran belaka dan tidak diwujudkan serta ditumbuhkan tanggung jawab para penghuni untuk menjaganya. Akibat minimnya pemahaman mengenai konsep hijau tersebut, para pengembang perumahan cenderung lebih banyak menawarkan lingkungan perumahan yang asri dan hijau, bukan konsep hijau yang sebenarnya.Kata Kunci: Sosio-kultur, Efisiensi Energi, Konsumsi energi, Lingkungan, Konsep Hijau

Abstract:

Climate responsive design can amplify the positive environmental effects necessary for human habitation and constructively engage and reduce the energy use of existing buildings. This paper aims to assess the role of the thermal adaptation design strategy on thermal comfort perception, occupant behavior, and building energy use in twelve high-performance Belgian households. Thermal adaptation involves thermal zoning and behavioral adaptation to achieve thermal comfort and reduce energy use in homes. Based on quantitative and qualitative fieldwork and in-depth interviews conducted in Brussels, the paper provides insights on the impact of using mechanical systems in twelve newly renovated nearly- and net-zero energy households. The article calls for embracing thermal adaptation as a crucial design principle in future energy efficiency standards and codes. Results confirm the rebound effect in nearly zero energy buildings and the limitation of the current building energy efficiency standards. The paper offers a fresh perspective to the field of building energy efficiency that will appeal to researchers and architects, as well as policymakers.

Abstract:

Efforts have been put in place to minimize the effects of construction activities and occupancy, but the problem of greenhouse gas (GHG) emissions continues to have detrimental effects on the environment. As an effort to reduce GHG emissions, particularly carbon emissions, countable commercial, industrial, institutional, and residential net-zero energy (NZE) buildings were built around the globe during the past few years, and they are still operating. But there exist many challenges and barriers for the construction of NZE buildings. This study identifies the obstacles to developing NZE buildings, with a focus on single-family homes, in the Greater Toronto Area (GTA). The study sought to identify the technical, organizational, and social challenges of constructing NZE buildings, realize the importance of the public awareness in making NZE homes, and provide recommendations on how to raise public knowledge. A qualitative approach was employed to collect the primary data through survey and interviews. The secondary data obtained from the literature review were also used to realize the benefits, challenges, and current situation of NZE buildings. Research results indicate that the construction of NZE buildings is faced with a myriad of challenges, including technical issues, the lack of governmental and institutional supports, and the lack of standardized measures. The public awareness of NZE homes has been found to be very low, thus limiting the uptake and adoption of the new technologies used in this type of homes. The present study also recommends that the government and the academic institutions should strive to support the NZE building technology through curriculum changes, technological uptake, and financial incentives to buyers and developers. The implementation of these recommendations may enhance the success and popularity of NZE homes in the GTA.
