Projects of a certain scope can simply take a while, and such is the case with this medical complex. We check in seven years after the site evaluation but still a year or two away from opening. It’s a good time to ask some questions: How do you plan for equipment that isn’t invented yet? How do you keep adjusting design once construction has started? Explore the obstacles - plus intricacies, such as how the BAS works with emergency power - that make such planning anything but child’s play.
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.
