As the importance of building indoor environments has increased recently due to the COVID-19 pandemic, so has the research on the interrelationship among daylight, human health, and building design. More researchers are studying how daylight affects human health and whether currently known daylighting metrics target human health in addition to building environmental performance. This article provides an updated review of the current review of the literature in the field of daylighting design and human health, particularly as it relates to the impact of daylighting on circadian rhythm, sleep quality and performance. The main objective for this study is to analyze the interrelationships between daylight, health, and design. The review of these articles reveals eight different factors relevant to daylight, in terms of the way daylight impacts people’s health, namely light spectrum, light levels, timing and duration of exposure to light. In terms of health impact, these articles outline direct and indirect health outcomes. In addition, our review of the existing literature indicates that there is a lack of proper daylighting metrics as far as design applications.

The publication of the Brundtland Commission Report, popularly known as Our Common Future, was the precursor for what was to follow in Rio de Janeiro in 1992, the United Nations Conference on Environment and Development or the Earth Summit. Both these events played a fundamental role in the global initiatives towards sustainability. The adoption of Agenda 21, a blueprint for sustainable development for the 21st century was a crucial agreement of the Rio Summit, which marked the beginning of an era where the term Sustainable Development came to be associated with all human interventions on planet earth. In this context, the building industry, which makes a significant impact on the social, environmental and economic well-being of the society, has a prime responsibility in meeting with sustainability requirements in all facets of the design, construction and operation of buildings. Currently efforts are being made by the building industry and the allied professions to adhere to sustainability norms by enhancing the current green building practices. The emergence of building environmental assessment (BEA) methods is such an attempt in addressing these issues, but is considered as insufficient to contend with the wider spectrum of sustainability. A technique to address complex attributes of sustainable performance of building projects has not been attempted before, owing to the dynamic nature of the concept of sustainability. This paper attempts to develop a framework to enhance current BEA methods, as the next stage of development towards meeting global sustainability initiatives. The main objective is to evolve a set of indicators that will assist in determining sustainability of a building. Three widely used BEA methods and Agenda 21, are analyzed, along with a focus group, to derive sustainability indicators. A total of 62 indicators under 10 categories are identified, some of which are common to BEA methods, while several new indicators are introduced to address sustainability issues not previously accounted for in BEA methods. The final outcome is a framework that can be used to determine the extent of sustainability of building projects. With the aid of the proposed framework of indicators, it is possible to develop a complete sustainability index by allocating values to each indicator, through a survey of professionals in the building industry. Such an index could be used as a tool in developing sustainable buildings, thus meeting with aspirations of building design teams and clientele who seek high quality sustainable solutions for their endeavours. This effort would also pave way for further research into the domain of building sustainability.

The challenge of quantifying sustainability is continuously debated in the building industry. There is an increased need for quantitative solutions to be developed for measuring and comparing performance. The Danish government has proposed a voluntary sustainability program to lift the bottom of the industry with regard to sustainability performance. This study evaluates the possibilities of increasing the sustainability reference level in the building industry based on expert interviews. The study was framed upon the multi-level perspective as a theory to describe the transition to sustainability. The results indicated that existing knowledge and experience within the topics of the regulatory changes is high in the industry. Therefore, the impact of the changes would not be very effective if they are not sufficiently innovative or demanding. Regarding the effect of the voluntary sustainability program, it was found that the program is not very ambitious and likely to only have an impact on companies with a lower level of ambition in terms of sustainable initiatives. The hope, however, is that it will keep raising the level of sustainability.

Daylight glare index (DGI), daylight glare probability (DGP) and glare-sensation (GS) predictive models are the widely used glare indices for the assessment of occupant visual comfort in daylit spaces. This paper presents the development and implementation of Machine Learning models to predict these glare indices. The training and validation data sets were collected from sensors incorporated in the test room with motorized Venetian Blinds and dimmable LED luminaires. Predictor and response data were obtained from conventional sensors, digital cameras, and the EVALGLARE Software. The regression models predict DGI and DGP, whereas the classification model predicts GS. In addition to standard statistical error evaluation metrics, the hypothesis test assesses the performance of regression/classification models. The results reveal that Ensemble Tree (ET) models are highly accurate at predicting glare indices. The proposed technique attempts to simplify the existing traditional Glare Index(GI) estimation method. The combination of real-time daylight glare prediction and suitable window shading control increases occupant visual comfort. A high dynamic image-based system is employed to verify the measurements made using traditional sensors.

This research presents the current state of understanding on strategies to update green building rating tools (GBRTs). Based on existing literature, the study determined the GBRT-updating requirements (URs) and their related technical elements (TEs) and integrated them to form a system framework through Functional Quality Development. The framework emphasizes the interaction and balance between expert deliberation and stakeholder participation, and fully considers the complementarity between international experience and local practice. Subsequently, the Fuzzy Analytic Hierarchy Process was used to determine the relative importance of URs while the Fuzzy Set Theory was used to quantify the correlation between URs and TEs. Finally, the Green Building Index (GBI) was used as the research sample to apply the proposed model, whose outputs were then analyzed by using the Importance-Performance Analysis method. Then, appropriate technical improvement suggestions for the updating of GBI were derived. The study explores the technical update of GBRT in the form of extensive participation and utilizes the knowledge complementarity among decision-makers. Furthermore, the proposed framework provides practical help to guide the update of GBRTs for developing countries.

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

Green roofs have become increasingly common in urban areas to slow and reduce stormwater runoff from buildings. However, phosphorus has been found to leach from green roofs. Water treatment residuals (WTRs), a waste product in the water treatment process, may help reduce leaching of phosphorus from green roofs. This study evaluated a green roof retrofit that consisted of a WTR filter at the green roof drain to reduce phosphorus in runoff. Samples of rainfall, runoff from a green roof, and runoff from a regular roof were collected every time it rained and analyzed for total phosphorus (TP), phosphate (PO43−), copper (Cu) and zinc (Zn). Samples were taken January–March 2020 and September 2020–March 2021. Phosphate and TP concentrations were significantly lower (p<0.05) with the retrofit during the winter (Jan–March 2020 and 2021) but not during the fall (Sept–December 2020). The change in WTR efficacy may be due to the WTRs drying out during the summer months, although it appears the WTRs are effective once they have been resaturated during the fall wetting period. This study shows that the WTR retrofit may reduce phosphorus leaching as long as the WTRs do not dry out. The WTRs should be replaced each fall in regions that experience dry summer months to maximize efficacy.

Green building product designs, which interact directly and extensively with building users through active operation (e.g., operating of a solar shade, windows, light switch) and/or aesthetic or creative features of the designs (e.g., decorations showing sustainability concepts), represent a critical link between users and buildings. Yet, the user-design interaction has received little attention in the green building design practices as shown from existing green building rating systems, which rely largely on scores obtained from simulation models without incorporating the human factor, leading to unsatisfactory performance. In this paper, we identify three factors which are important in the user-design interaction: 1) “usability” for measuring the utilitarian purposes fulfilled by product design for a green building; 2) “teachability” for evaluating the effectiveness of using a green building product design as a teaching medium; and 3) spatial configuration for assessing the spatial layout of products designed for promoting usability and teachability. Selection, weighting, and measurement of indicators for each aspect are developed through literature review, Delphi survey and analytic hierarchy process. A software tool is developed for data entry, processing, and visualization which can be adopted by the design community following two hypothetical case studies.

The research is based on the premise that in order for a building energy model to contribute to a sustainable energy future, the model’s accuracy must be ensured in order for the model’s results to be trusted. Therefore, validation processes in continuing Ghanaian building performance studies are outlined. The process started with long-term monitoring of low-rise, multi-storey and test cells structures. Combined with weather data from meteorological offices, reliance on synthetic weather files and local measurements, appropriate matching periods of weather data and measurements were used to simulate indoor parameters. Further, the simulated and measured data were in good agreement in terms of regression values (r2of 0.53–0.96). Energy use bills were used to validate energy loads of a multi-story building which resulted in a difference of 0.09% between the simulated and billed data. Furthermore, an approach of using the Coefficient of Variance for Root Mean Square Error (CV (RMSE)) was also presented. Considering the range of the regression values which could be due to the difficulty in the validating process; one can confidently rely on the outcome to predict building performance. Sampled challenges are the potential of synthetic weather files to overlook microclimatic conditions such as urban heat island effects; difficulty in predicting internal loads as comprehensive monitoring devices are lacking, e.g., occupancy sensors to monitor the actual number of people present at a time and their behaviour within spaces; system performance values which are known to decline with time, therefore, affecting measured versus simulated values; most firms not keeping energy bills and their unwillingness to provide the information to researchers; etc. The validated models can be used as scientific-based data and analysis to inform building designers decisions to reduce the economic and environmental burden in Ghana.

Considering the range of the regression values which could be due to the difficulty in the validating process; one can confidently rely on the outcome to predict building performance. Sampled challenges are the potential of synthetic weather files to overlook microclimatic conditions such as urban heat island effects; difficulty in predicting internal loads as comprehensive monitoring devices are lacking, e.g., occupancy sensors to monitor the actual number of people present at a time and their behaviour within spaces; system performance values which are known to decline with time, therefore, affecting measured versus simulated values; most firms not keeping energy bills and their unwillingness to provide the information to researchers; etc. The validated models can be used as scientific-based data and analysis to inform building designers decisions to reduce the economic and environmental burden in Ghana.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86876473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
