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.

The core business of our Energy Solutions division is the delivery of Guaranteed Energy Savings Performance Contracts (ESPCs). ESPCs allow us to upgrade and renovate facilities in a budget‑neutral or even budget‑positive way by directing money already spent on utilities into facility upgrades. The process covers scope development, design, bidding, construction management, commissioning, measurement and verification, and ongoing energy‑management services.

Our Energy Solutions division has a robust co‑op program for college students pursuing a degree in engineering. The program offers an immersive experience in Guaranteed Energy Savings Performance Contracting for one or more semesters, building industry skills through collaborative project tasks under the direct supervision of Professional Engineers.
