Roof insulation is crucial, since the sun beats on the roof all day. For large single-story buildings in southern climates, heat transfer through the roof can amount to as much as 30 percent of total cooling load, and higher insulation values are warranted. Engineers as friends Aside from making better design decisions, architects can work with engineers to avoid oversized HVAC systems by expressing interest in the central plant design. If the engineer knows that the architect and the owner want a realistic system, instead of one that guarantees the absolute comfort of occupants, everyone can work together more responsibly. Let the engineer know that oversizing is not acceptable, Clanton says.
Architects can help by providing accurate occupancy and plug load estimates.
Postoccupancy measurements of previous buildings provide some real-life examples. Willingness to work with the engineer, to approach the liaison as a way to solve problems and save money, will mean a better, more comfortable building and a happier owner.
