The ENVOCORE team has thousands of projects, literally millions of hours of project design and implementation under our belt! While no two design/builds are ever the same, with ENVOCORE as your partner, you can rest assured our employees have the depth of knowledge and experience to get the most out of your project. We get it done right, on time, on budget, and always put safety first. With offices in the United States and Canada, ENVOCORE is ideally positioned to serve energy service companies (ESCOS) worldwide with innovative, state-of-the-art, energy-efficient solutions that provide measurable waste reduction. ENVOCORE roots go back to 1993. Two independent lighting companies were started in two different parts of the country: RTS in Chicago, and LRI in Gambrills, MD. Each focused on light design and energy conservation. Over 20+ years both RTS and LRI grew their services, expertise, service areas and portfolios. In June 2017, Retro-Tech Systems (“RTS”), which includes RTS Lighting, RTS Water, RTS Utility Metering, and RTS Building Envelope, joined LRI Energy Solutions (“LRI”), including wholly owned subsidiaries Lighting Retrofit International, Water Savers and Enlight to form a new company, ENVOCORE. Like the companies that created it, ENVOCORE is dedicated to the growth and success of the energy solutions market.
