Commercial Energy Toolkit

The commercial sector includes offices, hotels, restaurants, convenience stores, doctor’s offices, and places of worship.

Commercial buildings are responsible for consuming approximately 16% of the energy consumed within Pennsylvania. Due to the variety of types of buildings within the commercial sector, the overall energy usage will vary by subsector.

This toolkit provides you with the same initial steps we would take to start assessing energy savings potential in a commercial building. Some of these changes you can make on your own, while others may require further consult and an expert energy audit. You can explore our case studies below to learn more. Be sure to contact PennTAP with any questions or to schedule a virtual audit.
