SES is an Energy Efficiency Engineering firm and a social enterprise. Efficient buildings are a major part of the solution to a sustainable future and we bring the tools our clients need to achieve results.

We’ve been growing and innovating since 1975, and what we’ve learned is that more than excellence in HVAC or building automation, the key to energy efficiency is long-term savings.

SES works in partnership with our clients to ensure recommendations are properly implemented and operators understand the technology. Systems are monitored and managed for optimal performance.

Buildings are more than bricks and mortar, they are spaces for people. SES is leading a transformation in building management to more sustainable, healthier, and happier work environments.
