The Center for the Built Environment (CBE) Thermal Comfort Tool is a free online tool thermal comfort calculations and visualizations that complies with ASHRAE 55–2017, ISO 7730:2005 EN 16798–1:2019 Standards. It incorporates major models, including Predicted Mean Vote (PMV), Standard Effective Temperature (SET), adaptive local discomfort SolarCal, dynamic predictive clothing insulation. Our also provides interactive of zones. CBE has several practical applications each year used by more...
Abstract Urban overheating, driven by global climate change and urban development, is a major contemporary challenge that substantially impacts livability sustainability. Overheating represents multifaceted threat to the well‐being, performance, health of individuals as well energy efficiency economy cities, it influenced complex interactions between building, city, scale climates. In recent decades, extensive discipline‐specific research has characterized heat assessed its implications on...
Several relationships between air temperature and work performance have been published. We reanalysed the one developed in 2006 by Seppänen et al.; which is probably best known. found that even when significant, its prediction accuracy very low (R2 = 0.05, MAE 1.9%, RMSE 3.1%). consequently reviewed literature 35 studies on effects of office performance. used al.'s approach to normalise data reported these explored feasibility develop a new relationship using regression models, models based...
Luminance adjustment is widely used to evaluate discomfort due glare. This paper reports an experiment conducted investigate two factors of the luminance procedure, stimulus range bias and direct vs indirect control. Stimulus describes influence on subjective evaluations stimuli available test observer, with being minimum maximum glare source in current context. For source, artificial window, there were three ranges, having luminances 5 106, 7288 9469 cd/m2. The results suggest that had a...
Bus cabin air quality has not been incessantly monitored in Hong Kong. This study investigates the in-cabin exposure levels of CO, CO 2 and PM 10 for running buses Kong that are equipped with Euro II, III IV engines. A representative urban—suburban bus route was chosen there were no significantly different reported among engine types between rush non-rush hours. However, level found associated ambient/roadside level; former altogether higher than latter due to bus’ own exhaust. Regarding...
Potential bioaerosol infection risk associated with toilet flushing has not been sufficiently addressed in the design of residential washroom exhaust system. This study evaluates performance ventilation for washrooms terms air change rate, size, geometry, and locations door louver, water closet. Three species namely Escherichia coli (ATCC 10536), Serratia marcescens 6911), Cladosporium cladosporioides 16022) are included simulations. By shortening distance between emission source (i.e....
Replicating scientific findings is a fundamental aspect of research. However, in studies discomfort due to glare, it difficult make comparisons between the results different experiments since statistical tests usually reported do not allow independent be directly compared each other. Here we present an alternative Bayesian approach that can address this problem. To show how works, performed laboratory test with 55 participants validate effect order bias previously detected similar study...
Energy efficiency in buildings is a key factor for sustainable development. This study examines the electricity consumption apartments and communal areas both public private housing Hong Kong. A tool based on Monte Carlo sampling has been developed to predict residential terms of type, occupant load per apartment (tenant) gross floor area building (communal). The demand forecasts Kong show that substantial energy savings (>670 GWh yr −1 ) can be achieved over next decade through adjusting...

Air-conditioned offices in the subtropics are recommended to operate within specified ranges of indoor temperature, relative humidity, air velocity, and carbon dioxide concentration for thermal energy conservation. As environmental discomfort leads productivity loss, this study investigates impact an policy on Grade A served by different airside systems terms consumption, comfort, loss. Occupant response is specifically considered as adaptive factor evaluation consumption Simple Monte Carlo...
SARS-CoV-2 has been recognized to be airborne transmissible. With the increased transmissibility leading increasingly reported positive cases, home quarantine is adopted for infected patients who are not seriously ill. However, risk of household aerosol transmission well studied. We conducted tracer gas experiment simulate exhaled virus laden aerosols from a patient under situation inside residential testbed. The Sulphur hexafluoride concentration (SF 6,conc ) was measured both and outside...
