While active beams are making great strides toward becoming a standard part of the designer’s toolbox, knowing when to deploy them is a critical judgment. The author focuses his considerable experience with them into a good look at related thermal comfort considerations. Operation and controls, two- and four-pipe systems, and condensation control strategies round out a worthwhile look at how active beams can work for you.
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.
