Our design and installation expertise lies in HVAC system upgrades and replacements, LED lighting upgrades, indoor air quality analysis and improvements, building automation system optimization and commissioning, energy auditing, water conservation, and on-going performance management services.


Our business development folks work with clients to understand their facility problems and offer custom solutions understanding each client is unique. Brand and product neutrality means we develop projects that fit our clients and don’t make our clients fit a product.


Having engineers in-house allows us to own our projects from start to finish. E3 is a turnkey firm that delivers projects for the price stated. If we miss something, we fix it out of our pocket and work until it’s right.


We only build what we design. Stellar communication between our engineers and project managers, coupled with extensive knowledge of construction best practices, ensures projects are done right the first time.


We stay connected after the scope of work is complete. Performance Management is our commitment to an ongoing partnership with our clients to ensure facilities operate efficiently and comfortably for the long haul.
