A wet-bulb economizer in temperate U.S. climates saves energy and supports occupant health through proper humidification by controlling the building supply dew-point temperature.

Climate change and global warming have led to an increase in wildfires from coast to coast. HVAC design professionals are now pressed to provide indoor environments that are both low cost and supportive of occupant health and productivity
