Most states have yet to adopt the most current residential building codes. And, while current residential model building codes require higher ventilation rates and energy-efficiency requirements than ever before, they still lag behind commercial codes.
“You don’t have universal code acceptance like you do on the commercial side, and there’s no universal acceptance of ASHRAE Standard 62.2 in any of the codes,” said Drake Erbe, chair of ASHRAE Standard 90.1 and vice president of market development at Airxchange Inc. “So, while you might have 62.2-2001, you don’t have the most current version being adopted.”
