“…Being a state of mind supposes that it remains a subjective endeavor and thus differs for various individuals. However, thermal comfort is maintained when there is a “balanced exchange of heat between a person's body and the environment, marked by the absence of regulatory sweating” (Senin and Mydin, 2013). It is often viewed as the most critical factor of IEQ, as it plays a paramount role in occupants’ comfort and satisfaction (Esfandiari et al , 2017) and has been said to affect productivity and performance health (Senin and Mydin, 2013).…”

“…However, thermal comfort is maintained when there is a “balanced exchange of heat between a person's body and the environment, marked by the absence of regulatory sweating” (Senin and Mydin, 2013). It is often viewed as the most critical factor of IEQ, as it plays a paramount role in occupants’ comfort and satisfaction (Esfandiari et al , 2017) and has been said to affect productivity and performance health (Senin and Mydin, 2013). When dealing with thermal comfort, six variables are considered: air temperature, radiant temperature, humidity, air speed, metabolic rate and clothing insulation (ASHRAE standard 55, 2017).…”

PurposeThe excellence in design and greater efficiencies (EDGE) certification system has seen a gradual adoption worldwide, with Ghana having six out of its eight certified green buildings bearing an EDGE certification. However, little is known about occupants’ satisfaction with the indoor environmental quality (IEQ) of EDGE-certified buildings. Therefore, the purpose of this study is to examine the satisfaction of occupants with the IEQ of an EDGE-certified building in Ghana by identifying their perceived performance of the indoor environment relative to their perceived importance.Design/methodology/approachA survey was conducted to evaluate the performance of 12 IEQ parameters with the occupants of an EDGE-certified office building. The survey results were evaluated using a gap analysis and both traditional and alternative Importance-Performance Analysis (IPA) matrices.FindingsThe findings revealed that noise level, temperature, cleanliness, sound privacy, air quality and humidity were IEQs that required the highest priority for improvement. Daylight and artificial lighting showed no appreciable performance gap. Space layout was adequately satisfied, whereas space size was overly satisfied. Visual privacy and outdoor view were found to require low priority of improvement.Originality/valueThis study contributes to the state-of-the-art of the IEQ of green buildings. It pioneers the research that seeks to examine the IEQ of EDGE-certified buildings. The gap analysis and the IPA were effective in prioritizing the IEQs for improvement action and provided a practical research framework that helped researchers examine the performance of green buildings, thereby giving valuable feedback to policymakers and building owners.

Assessment of Summer Overheating in Concrete Block and Cross Laminated Timber Office Buildings in the Severe Cold and Cold Regions of China

et al. 2021

The aims of the paper were to clarify whether office buildings in the severe cold and cold regions are overheating, especially those with natural ventilation, and whether potential overheating is related to the building materials. The severe cold and cold regions of China were considered to be cool regions during summer. However, with global warming, improvements in the thermal performance of the building envelope and the urban heat island effect, office buildings in these regions are showing different degrees of overheating during summer. Two office building materials commonly used in this area, cross laminated timber (CLT) and concrete block, were simulated in this study. With reference to the overheating standard, the degree of overheating in six cities in the severe cold and cold regions was quantitatively analysed and the extent of overheating for the two building materials was compared. Finally, the influence of thermal insulation on building overheating is discussed, and some suggestions are put forward to improve the relevant national regulations in China. The results show that office buildings in the severe cold and cold regions experience overheating during summer, and CLT buildings are more prone to overheating than concrete buildings during summer. This is attributable to the different thermal mass of the materials. Thick insulation does increase the risk of building overheating, and the effect on concrete buildings is more pronounced. Concrete buildings with an insulation layer can experience overheating for 27–71 h more than buildings without an insulation layer. Insulation on CLT buildings only results in an increase of 11–37 h. When considering the current situation with summer overheating in the severe cold and cold regions, relevant codes should also be modified and improved accordingly to guide building design, so as to achieve low-carbon and energy-saving goals.
