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, competitive innovative, and energetic group of engineers and team leaders who incorporate a holistic approach towards consulting engineering, performance contracting, and zero energy projects. We focus on finding engineers whose personalities lead them to excellence, and we provide exceptional opportunities for our employees.

The core business of our Energy Solutions division is the delivery of Guaranteed Energy Savings Performance Contracts (ESPCs). Simply put, 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. CMTA Energy Solutions has a robust co‑op program for college students pursuing a degree in engineering. We offer an immersive experience in the world of Guaranteed Energy Savings Performance Contracting for one or more semesters. Our co‑ops build competitive industry skills in a hands‑on environment through collaborative project tasks with full‑time engineers while under the direct supervision of Professional Engineers. Our program is designed to develop students into full‑time caliber employees that contribute to the company’s growth. The ideal candidate will possess excellent interpersonal skills and will be able to work well both as a team member and independently. Our program stands apart from the typical, rehearsed co‑op rotation in which every co‑op gains the same experience because it is designed for co‑ops to stand out and take on challenging projects. Co‑ops will be involved with multiple Guaranteed Energy Savings Performance Contracts and will have a role in every stage of their development. Each stage offers a variety of valuable experiences, from initial development through implementation. Whether co‑ops are interested in building their skill set in identifying and calculating energy savings measures, developing renovation documents, or hands‑on field experience, CMTA Energy Solutions is bound to overcome expectations. Lighting Co‑ops can expect to get hands‑on experience with commercial lighting systems.

By the end of the program co‑ops will have gained the experience to be able to deliver a full LED lighting upgrade design from scratch. Our Lighting co‑op will directly support our lighting project managers.
