FirstLight is a boutique engineering firm on a big mission to decarbonize the built environment.

We are a team of mechanical engineers, systems thinkers, and energy thought leaders with 50 years of combined industry experience translating complex problems into elegant and practical solutions. 

Our mission is the equitable decarbonization of the building sector. We know we can't solve the problems of yesterday using the thinking that created them—and we can’t do it in silos.

We believe that urgent attention is required to decarbonize the built environment. We are committed and passionate about applying our expertise to solve this challenge. We believe our collective experience and diversity will drive innovation and equitable solutions to meeting our climate goals.

Big picture matters. Details matter. Drawing connections between these two is where the magic happens. And this is where we thrive as a team. We are intentional, focused, and goal-oriented.
