Review of Parameters Measured to Characterize Classrooms’ Indoor Environmental Quality

As attention to indoor environmental quality (IEQ) grows, a systematic strategy for assessing IEQ in schools needs be developed. For this purpose, paper presents summary of parameters measured school classrooms characterize the thermal, acoustic, and visual environments air (IAQ). The is based on review published literature reporting measurements Europe North America past ten years. It also summarizes measurement protocols concentrations. Eighty-eight papers describing were identified analyzed. No unique standardized measuring method was used reviewed studies different measured. most often those thermal environment IAQ. former mainly comprised temperature relative humidity. latter concentrations carbon dioxide, particulate matter, radon, formaldehyde, some volatile organic compounds. acoustic noise level, reverberation time, illuminance. A few reported additional radiant temperature, operative speech intelligibility. Measurement from show inconsistency sampling duration location expressed results. Measured high variation between studies, with pollutants exceeding threshold values proposed by local and/or international organizations such as World Health Organization (WHO). This provides reference developing rating scheme uniform characterization classroom IEQ.
