A hospital with a smart HVAC design can still suffer mold if
maintenance misses a beat. Likewise, the best O&M regimen can’t
avoid the consequences if the HVAC is designed for the wrong
temperature range, or if the humidity level is anyone’s guess. Prevent
unwanted condensation and worse with this condensed look at both sides
of the IAQ coin.
Leaning on experience and data from various K-12 cities and projects, the author pursues 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.
