| Abstract | |
Thermal comfort and indoor air quality are important factors to be considered during building design and operation. This study aims to evaluate thermal environment conditions during air conditioning system operation through field measurements in summer. The survey was conducted in nine office buildings with mechanical cooling in São Paulo. Measurement strategy and statistical determination of the number of samples per building were determined in accordance to the results of initial measurements. Environmental parameters data was collected with corresponding instrumentation in buildings and then compared with the levels required by national and international standards for thermal comfort and indoor air quality in order to verify air distribution efficiency in regard of pollutants removal, based on carbon dioxide concentration, and the provision of comfort through the analysis of variables such as temperature, relative humidity and air velocity. The results showed that most of the sample fitted into the categories of thermal environment established by the standards and that there is potential for saving energy in air-conditioned buildings in Sao Paulo.
