Lighting is changing very quickly. Most understand the technology change, but few understand how light affects human physiology. Advancements in technology have enabled us to design lighting for human performance. EPL’s mantra is “get lighting right for the occupant of the space and the energy savings will naturally fall into place”.

Step back and think about evolution, all life began with light. We spent a million years getting up with the sun and going to bed with the sun. Only in the last hundred years has that really changed. Below is a spectrum of natural daylight and light under a fluorescent lamp. The difference in spectrums is obvious.

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).
