About this appendix: Harnessing the heat or radiation from the sun's rays is a method to reduce the energy consumption of a building. Although Appendix T does not require solar systems to be installed for a building, it does require the space(s) for installing such systems, pro- viding pathways for connections and requiring adequate structural capacity of roof systems to support solar systems.

Section numbers in parenthesis are those in Appendix A of the residential provisions of the International Energy Conservation Code ® .
