2021 PA Alternative Residential Energy Provisions Now Available

Date: 11/5/2021

The 2021 Pennsylvania Alternative Residential Energy Provisions (PA-Alt) have been successfully published! This document will be incorporated into the PA Uniform Construction Code on the effective date of the 2018 ICC code provisions, as adopted, on February 14, 2022, in the Commonwealth of Pennsylvania.

The PHRC developed the PA-Alt for consideration by the Pennsylvania Department of Labor & Industry (DLI) to meet their legislated mandate to consider the development of alternative prescriptive methods for energy conservation that account for the various climatic regions within the Commonwealth per Act 45 of 1999. The PA-Alt was developed with the intent of being simpler to build to and easier to enforce; more rational and flexible; focused on Pennsylvania in terms of climatic and other conditions; and equivalent to the provisions of the International Energy Conservation Code (IECC). The 2021 PA-Alt is equivalent to the 2018 IRC and the 2018 IECC.

The development of the 2021 Pennsylvania Alternative Residential Energy Provisions (PA-Alt) was led by the PHRC with guidance from a subcommittee of the PHRC Industry Advisory Council. The PHRC would like to recognize the following members of the PA-Alt Subcommittee for their contribution of time and knowledge: Charles Bond, Jerry Leach, Robin Loughran, R. Clem Malot, Amy Martino, Tom McCosby, Chad Owens, Jim Royer, Tommy Songer, Jon Sukonik, Paul Szostak, and Mike Turns.

This document was developed by Brian Wolfgang, associate director; Christopher Hine, residential design & construction specialist; and Sarah Klinetob Lowe, high-performance housing specialist of the PHRC. Energy equivalence analysis was performed by Sarah Klinetob Lowe. The document design and formatting were completed by Rachel Fawcett, financial & communications coordinator of the PHRC.
