Based on the factors that influence the indoor comfort situation, a new index Comprehensive Percentage Dissatisfied CPD is proposed, which depends on the thermal factor, noise and indoor air quality. The calculation formulas in CPD are described in this paper and a method called gradation analysis is used to deduce the values of each coefficient in CPD. Finally, the index CPD is used to evaluat...

As s‌tudents spend one-third of their time at school, their health, comfort, and productivity are mos‌tly influenced by thermal condition and indoor air quality of classrooms. Regarding that manual window-opening is a common way for providing fresh air in classes and s‌tudents aren't allowed to change their uniform, position or control the windows during the lesson hours, providing thermal comf...

OBJECTIVE The aim of this study was to evaluate the relationship between the severity of AD and indoor air pollution. METHODS The study population consisted of 425 children from 9 kindergartens, Ko...

An investigation method to evaluate microbiological air quality has been developed; it involved a compiling building inspections checklist and occupants questionnaires, choosing sites, sampling frequency and analysis procedures. This method has been applied in a representative building with HVAC system and open-space offices. Air samples and microclimate parameters were collected at the same ti...
