Does DOE have a recommendation on the thermostat setting for classrooms?
Yes. The American Society of Heating and Refrigeration Air-conditioning Engineers (ASHRAE) recommends that temperatures be kept from 73.0- 78.5F in the cooling season, and 67.5- 74.0F in the heating season (i.e., winter). ASHRAE’s recommendations are based on comfort. A concern during the cooling season is cooling the classroom air below the dew point of the air outside. Condensation and mold growth can result. Heat is our friend with regard to keeping buildings dry and preventing mold, so we recommend trying to bear temperatures of 76.0- 78.5F in the cooling season.
