EPL is a state certified Energy Service Company (ESCO) in Wisconsin and has successfully installed numerous lighting system upgrades through performance contracting since 2009. Our projects include Investment Grade Audits based on careful benchmarking of existing conditions, photometric design with best industry practices to maximize cost savings, and measurement and verification actions to confirm the savings. Our performance contracts include guaranteed utility savings to ensure the project payback is within the calculated time frame. This performance guarantee means if the project does not pay back within the calculated time frame, we will correct the lighting system so it does or pay the owner the difference in the annual energy cost savings.

Our Process

We conduct our lighting energy assessments in accordance to the Illuminating Engineering Society's Guidelines for Upgrading Lighting Systems in Commercial & Institutional Spaces.  The information we collect then becomes the basis for our in-depth requirements analysis and design development.

Building on the design fundamentals of Task, Technology and Controls, our team of experts takes your lighting upgrade from concept to final proposal.  Our manufacturer and technology neutral solutions are also designed to the specifications of the Illuminating Engineering Society's Lighting Handbook, 10th Edition, which meet or exceed EPACT 2005 and ASHRAE90.1, 2010 requirements.

Our professional installation staff performs the lighting upgrades in accordance with your operational needs and goals identified during our assessment.  EPL project managers, site supervisors and installation teams comply with applicable safety and labor regulations and codes.

Using light level and amperage meters, we collect measurement and verification readings to ensure the effectiveness of our design and confirm the savings guaranteed by our design.  Our measurements are performed in designated locations on the lighting design, by a Certified Master Electrician, in accordance with guidelines established by the Pacific Northwest National Laboratory for the U.S. Department of Energy’s Federal Energy Management Program (FEMP LE-A-02).
