Inside Design Temperature
The desired inside design temperature will depend upon the intended use of the space. In a large structure, such as a hotel or a hospital, there will be more than one inside design temperature because there is more than one type of space usage. For example, hospital kitchens will generally have an inside design temperature of about 66°F. The wards, on the other hand, will range from 72 to 74°F.
Residences will generally have a single inside design temperature for the entire structure, with 70 or 71°F the most commonly used temperatures.
