That’s helpful for data center designers, but applying a little thought and site-specific consideration can reveal the path to wisdom in areas like failure rate, noise, power draw versus temperatures, and more.
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.
