In this overview of a three-school hydronics project in Texas, the author demonstrates how control is critical and why it’s worth putting some thought into alternate design scenarios along the way. He also offers a couple of tips for retrofits in constantly occupied spaces.
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.
