Residents’ participation in energy performance certification for collective action on climate change: the case of EnerGuide

IntroductionAlthough governments have launched energy performance certification (EPC) programs to increase residential energy efficiency, residents’ perception and acceptance of these programs have been little studied. This study contextualizes residents’ intentions to participate in EPC programs in terms of their attributions to and attitudes toward climate change to find mediating factors and effects to help trigger collective action to reduce residential sector energy demand.MethodsThis study employed a partial least squares structural equation modeling approach to empirically analyze a survey conducted on 400 residents of Edmonton, Canada, who participated in the Canadian energy efficiency rating and labeling program, EnerGuide.Results and DiscussionUsing EnerGuide, a Canadian energy efficiency rating and labeling program, as an example, this study establishes a framework to explain that local residents’ internal and external attributions to climate change elicit positive attitudes (need to take action), increasing their recognition of energy efficiency program benefits, which further promotes their EnerGuide program acceptance and participation intentions. This study also reveals the mediating effects between variables. Residents’ attitudes toward climate change mediate the relationship between internal/external attributions and EnerGuide program acceptance, and they indirectly impact residents’ program acceptance and participation intentions, with this effect moderated by energy efficiency program benefits. Residents’ program acceptance also mediates the relationship between climate change attitudes/energy efficiency program benefits and the intention outcome.ImplicationThe study provides an example of the use of climate change discourse to motivate residents’ energy efficiency program participation

Maslow in the Mud: Contrast between qualitative and quantitative assessment of thermal performance in historic buildings.

This paper argues that the notion of comfort is first and foremost re-lated to subjective choices and individual value systems. The article presents re-sults from research on the perception and measurements of the thermal qualities of heritage buildings in Lincolnshire, UK. The qualitative and quantitative re-sults identified a strong contrast between different methodologies. Inhabitants describe as comfortable houses which would not be considered comfortable if a standard positivist approach was used. The conflict presented will be dis-cussed in the context of sustainable strategies in architecture

Human Factors in Green Building: Building Types and Users’ Needs

The Special Issue on “Human Factors in Green Building” addresses the design of indoor environment quality for users’ needs. The collected papers cover various building types and the research highlights the different needs of users. In working environments, employees’ stress is the main concern in the workplace design, especially for open plan offices where lack of privacy and over exposure to environmental stress have been reported. In residential environments, residents have great opportunities to adjust their environments to suit their needs; therefore, passive design such as natural ventilation is explored in residential buildings with climates such as cold or humid tropical. In healthcare environments, the papers in this issue are concerned with the needs of patients, especially the older adults who require special care. In learning environments, thermal and visual aspects are investigated for optimal comfort conditions and learning outcomes. The special issue demonstrates insightful critical thinking of indoor environment quality and proposes a new understanding for more practical design solutions. This editorial note is a brief review of the 12 papers, concluding with reflections about design of built environments to meet users’ needs

The Impact of Outdoor Views on Students’ Seat Preference in Learning Environments

A Good learning environment should support students’ choices and attract them to stay. Focusing on outdoor views, this research explores two questions: How important outdoor views are in seat selection in learning environments? How do the view elements influence students’ seating behaviors in learning environments? A seat preference survey and view elements and occupancy rate measurements were conducted in a university library building in Gold Coast, Australia. This study not only echoes the previous research indicating that territory and privacy are important factors for choosing seats in a learning environment; more importantly, this study contributes to the literature with evidence that outdoor views might be an important factor for seat preference. Specifically, sky views and shading views were found positively related to occupancy rate. Based on this point, open views with appropriate shading were found as an optimal outdoor view composition. The singularity of greenery views would less likely be attractive to building occupants

Human Factors in Green Building

World Green Building Council suggests that health, well-being and productivity should be the next chapter for green building. There is an obvious shift of green building movement from technology-centric towards human-centric, which culminates in recent WELL Building Standard, focusing exclusively on human health and wellness. This special issue aims to push forward the research, discourse and practice of green building towards more human-oriented design solutions. Particularly, this special issue collects papers on: Post-occupancy evaluation of green buildings Indoor Environmental Quality (IEQ) Thermal Comfort and Adaptive Behaviors Quality of Life and Housing Healthcare Desig

A Review of Roofing Methods: Construction Features, Heat Reduction, Payback Period and Climatic Responsiveness

The roofs of buildings play an essential role in energy efficiency because a significant amount of solar radiation is absorbed by roofs in hot weather and a significant amount of heat is lost through roofs in cold weather. This paper is a systematic literature review about roofing methods for flat roofs. Ten roofing methods are reviewed in this paper. They are concrete roof, cool roof, insulated roof, roof garden, photovoltaic panels’ roof, biosolar roof, double-skin roof, roof ponds, skylight roof, and wind catcher. The review covers each roof’s main features, heat flux reductions, payback periods, and the appropriate climate for its implementation. Furthermore, the basic principles for selecting appropriate roofing methods are discussed and future studies for integrating these roofing methods are suggested. Some of these methods can eliminate the need of installing HVAC (Heating Ventilation and Air-conditioning) systems and others can achieve a high percentage of heat reduction if they are the right choice and they are implemented in the right circumstances. An incorrect selection could result in mild to severe energy penalties. The review contributes to the increasing knowledge about sustainable roofing and helps designers to increase building energy efficiency by selecting the appropriate roofing method

Are Green Spaces More Available and Accessible to Green Building Users? A Comparative Study in Texas

Green buildings (GBs) and green spaces (GSs) play a key foundational role as important drivers of urban Sustainable Development Goals (SDGs). There have been many studies on the spatial distribution of GBs and GSs, but relevant studies exploring the spatial relationship between GBs and GSs are lacking. The research questions were: whether GBs are more likely to access GSs than nongreen buildings (NGBs) and whether GBs with higher certification levels are more likely to access GSs. In this study, we used Texas and its four major cities (Austin, Dallas, Houston, and San Antonio) as case studies to compare the availability and accessibility of GSs to GBs (certified by Leadership in Energy and Environmental Design, LEED by U.S. Green Building Council) and NGBs. The study was conducted using spatial analysis tools in a geographic information system (GIS) to explore the spatial distribution of GBs and quantify the availability and accessibility of GSs in a comparison of GBs and NGBs and different GB certification levels. The study found that GBs in each city showed uneven distribution with multicore distribution. In addition, the availability and accessibility of GSs for GBs are lower than for NGBs, and the ability to obtain GSs does not increase with higher GB certification levels. This is because many GBs are located in areas far from the city center or in small cities around large cities where there are few GSs available, resulting in a mismatch in the distribution of GBs and GSs. The study also reviewed the certification manuals and found that LEED has regulated GSs at the city and community levels, yet has ignored them at the building level, and thus further suggests specific improvements. This study provides references and suggestions for adding GSs to the certification content, helping policymakers to optimize future efforts to improve GB certification programs and contributing to the eventual greater role of GBs and GSs together in urban SDGs

An Investigation of Green Roof Spatial Distribution and Incentive Policies Using Green Buildings as a Benchmark

The global spread of green roofs is becoming increasingly important in the context of increasing urbanization and climate change as they provide multiple benefits, including urban heat island effect (UHI) mitigation, stormwater retention and urban flood risk reduction. However, current research provides little insight into how green roofs are used and promoted globally. Therefore, it is essential to look at the global spatial distribution of green roofs and the related policies by using green buildings which have been successfully promoted as a benchmark. This study collected data from multiple sources, such as a dataset of spatial distribution of green roofs from eight countries, and 124 green roof incentive policy texts from 88 cities. Spatial analysis was conducted using ArcGIS Pro, and different types of incentive policies were explored using word frequency analysis. The results show that (1) the unbalanced distribution of green roofs in cities is prominent, with significant regional differences and clustering characteristics along water systems; (2) in the vast majority of countries, the types of incentive policies for green roofs lack diversity; (3) green roofs lack a well-developed rating system compared to how green buildings are promoted. Combining green buildings with green roofs and exploring the gaps between them, this study will help further explore the application of green roofs worldwide and guide governments or non-governmental organizations to develop and implement more efficient policies and provide recommendations to promote the popularity of green roofs worldwide

Addressing human factors in green office building design : occupant indoor environment quality survey in China

Although requirements in relation to indoor environment quality (IEQ) have been made in green building rating systems such as LEED (Leadership in Energy and Environmental Design) and China GBL (Green Building Label) to promote occupant comfort, health and productivity, in practice, very little is known about user perception and satisfaction with IEQ in green buildings. Recruitment and post-occupancy evaluation of 10 office buildings (8 green buildings and 2 non-green buildings) and their 696 occupants for this study generated a dataset representing many potential avenues of inquiry. From the occupant’s point of view, the green offices in buildings with whole-building certification were significantly more satisfactory than the non-green offices, whereas the green offices certified only on the basis of their interiors were comparable to the non-green offices. Mixed-mode ventilation performed much better than other ventilation types (central air-conditioning and split air-conditioning). However, the mixed-mode green buildings were invariably perceived to be too cold in winter. A correlation model showed that green building users tended to appreciate a well ventilated, daylit, and quiet indoor environment for their health and productivity. The findings in the study made critical suggestions with regard to pursuing green building certification and addressing human factors in sustainable building design and research. The strengths and weaknesses of this study were discussed to inform future studies.published_or_final_versionArchitectureDoctoralDoctor of Philosoph
