QuEST is an energy efficiency and energy management firm with a data-driven focus on verifying outcomes.

We are a small and growing business made up of engineers and project managers located in Northern and Southern California. Our team includes engineers, program/project managers, and support staff. We have been in business since 2001 and have strong connections in the California energy field that include relationships with major utilities. QuEST was the first to develop a local government partnership with a municipality (the City of Hayward) and played a sustainability advisory role in the early days of Silicon Valley Leadership Council.

We love that we get to protect and sustain our planet for work. We’re proud of the results we achieve for clients and we like to have fun. We believe in supporting the local community by buying local and we support a thriving bike commuting culture. Join us for a Friday morning ride in the East Bay hills!
