Indoor Air Quality and Thermal Comfort Assessment of Two Portuguese Secondary Schools: Main Results

Abstract

The results of the field study about indoor thermal comfort in two of the involved schools of the 3Es project are presented. The thermal comfort and indoor air quality assessment was conducted by monitoring physical parameters and survey questionnaires. The subjective assessment shows that the students found temperature range beyond the comfort zone acceptable, and revealed the occupants' accommodation to CO2 exposure. The CO2 exceeding values exposed that IAQ is a problem and action should be taken to promote CO2 dilution when HVAC systems are not active.
