Home Energy Efficiency and Conservation

The residential energy code for almost all of Pennsylvania is the 2015 International Energy Conservation Code (IECC). For Philadelphia, PA's only first-class city, the current residential energy code is the 2018 International Energy Conservation Code (IECC). Any new home construction or major renovation project which requires a construction permit, and that was obtained on or after October 1, 2018, must comply with PA's current energy code. The 2015 IECC substantially improves home energy efficiency and overall energy performance by more than 30%, compared to Pennsylvania's previous energy code, the 2009 IECC.

According to the US Census Bureau, over 80% of all homes in Pennsylvania were built prior to October 2009 - and PA's adoption of the 2009 International Energy Conservation Code (IECC). Consequently, this provides an excellent opportunity for significant energy conservation and energy efficiency savings improvements in your existing home.

Measure Your Energy Usage

How can you tell if your home is efficient? The first step to improving the efficiency of your home is to assess how much energy your home uses to help determine what measures you can take to improve energy efficiency.

Improving Home Performance

Taking steps to conserve energy and install energy efficient products and equipment will not only help you save energy, but will improve the environment and leave you with more disposable income for other necessities. Unfortunately, a "one size fits all" approach does not exist for energy efficiency and renewable energy in the home. Every home is unique – sometimes even on the same block! – as owners have changed windows or heating systems, or your house may be oriented differently to the sun or have a different number of occupants.
