On October 1, 2018, Pennsylvania began enforcing a new set of Uniform Construction Codes (UCC) that includes the 2015 International Energy Conservation Code (IECC). This replaces the 2009 IECC that was previously in place.

This change will have a substantial impact on residential new construction in PA.  It will greatly improve the energy performance of new buildings. As shown in the chart below, a house built to the new codes is expected to consume nearly 50% less energy than a house built in 1975 and about 25% less energy than a house built to the 2009 IECC.

Achieving these gains will require that numerous enhanced construction methods be utilized by builders and verified by code officials.

The major changes include:

This website aims to provide architects, builders, contractors, and code officials with accurate and technically-sound information on the energy requirements in the PA UCC.
