The 2018 Pennsylvania Alternative Residential Energy Provisions (PA-Alt) document is an alternative to chapter 11 of the International Residential Code (IRC). It is intended to supplement the IRC, and to the extent possible, to be consistent in format and general intent. The scope and definitions used in the IRC apply. It is important to note that a choice needs to be made by the builder or design professional between the 2018 PA-Alt, the 2015 IRC, and the 2015 IECC in Pennsylvania.
