A variety of factors affect people's environmental indoor comfort levels, including temperature, relative humidity (RH), air movement, clothing, activity level, and individual physiology. By regularly testing temperature, RH, and CO2 at various locations in the ventilation system, you can determine where and when air quality problems exist, identify the source, and maintain optimal comfort levels for building occupants.
From an occupant's perspective, these issues often translate into uncomfortable temperatures and humidity levels. Abnormal temperatures can affect both general comfort and people's ability to concentrate. Heating air lowers the humidity. RH below 30 percent can contribute to eye and respiratory symptoms. High humidity or water leaks can lead to mold.
