Frequently Asked Questions (FAQ)

Question:
I have a guy who is putting in a sliding door. Does he need T-24 Energy Calcs? If so, is there a simple form for meeting Package D requirements or does the project need to be modeled by computer?

ANSWER:
Alterations that add fenestration area do not require energy calculations if the fenestration product (i.e. sliding glass door) has a maximum .75 U-factor and meets the Solar Heat Gain Coefficient requirement of the Alternative Component Package D for the respective climate zone. Compliance can be documented on a Certificate of Compliance form CF-1R, a link is provided below for your convenience.
