Assessing The Radiant Road To School Design

The Radiant Roads To School Design

Leaning on experience and data from various K-12 cities and projects, the authors pursue some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
