The Indoor Environmental Quality (IEQ) of the modern workplace has become increasingly important to the building owner, the tenant, and its employees. Because the average employee spends up to 95% of the time indoors, the environment can have a direct effect on health, comfort, and productivity.

Two of the primary factors that are required for a suitable indoor environment are temperature and relative humidity (rh). Temperature control is always a considered parameter when designing a workspace. However, proper control of rh and its relationship to Indoor Air Quality (IAQ) are overlooked many times.
