COMPARISON OF THE PERCEPTIONS OF AMBIENTHAL COMFORT SENSATION IN AN AMPHITHEATER DURING THE SUMMER AND WINTER TIME

This paper provides information about the sensation of thermal comfort and indoor air quality (IV) for an academic amphitheater. The study was realized in the amphitheater on the ground floor of Faculty of Civil Engineering Timisoara class without mechanical ventilation system, on warm period (in May and Tune) and cold period (in December and January). Environmental comfort determination was made by measuring during classes the following parameters: indoor air temperature, mean radiant temperature, air velocity, relative humidity and carbon dioxide content (CO2). At the end of classes each student expressed his opinion about sensation of thermal comfort by completing some questionnaires, which were interpreted, resulting PMV and PPD parameters. Thermal comfort in the auditorium monitored was partly acceptable, but indoor air quality, namely carbon dioxide content (CO2) presented a serious increase.
