Polycom Inc came to Northern Energy Services to improve on a lighting system that was several years old. They were looking to attain a lighting upgrade due to the cost of maintaining the failing system as well as hoping to save and/or lower their energy use.
After visiting the site, we completed a no cost energy audit keeping the customer’s priorities in mind. Given the complicated wiring at their location, we were still able to develop and implement a turnkey solution that would entail a complete lighting retrofit replacing office, conference, mechanical, loading dock and common areas with the latest technology new energy efficient fluorescent lamps, ballasts, and fixtures.
