CMTA, a Legence company
CMTA is one of the fastest growing engineering firms in the U.S., with nationally recognized expertise in sustainable, high-performance building engineering. We are a collaborative, innovative, and energetic team that leverages a data-driven, holistic approach to consulting engineering, performance contracting, and zero energy projects. We focus on finding engineers whose skills and personalities drive them to excel, fostering a workplace that provides unparalleled growth and career opportunities.

The core business of our Energy Solutions division is the delivery of Guaranteed Energy Savings Performance Contracts (ESPCs) and Design/Build Contracts. Our ESPCs are a viable way to upgrade and renovate facilities in a budget-neutral or even budget-positive way. The process diverts money already being spent on utilities and directs it into facility upgrades, covering scope development, design, bidding, construction management, commissioning, measurement and verification, and even ongoing energy management services.

We have experience in designing the nation’s most energy efficient buildings, including many zero energy buildings. Our knowledge is unparalleled in the Guaranteed ESPC market, which allows us to dive deeper than our competitors.

In addition, CMTA’s Renewable Energy team brings extensive experience across the renewable energy sector, including behind-the-meter, front-of-the-meter, and community solar projects. Our team works in a wide range of building types, from dense urban environments to rural settings, and focuses on Solar PV, Battery Energy Storage Systems (BESS), microgrids, and EV charging infrastructure — delivering innovative, reliable, and sustainable energy solutions tailored to each client’s needs.
