CMTA, Inc.

CMTA, Inc. is a nationally recognized consulting engineering and performance contracting firm specializing in high-performance building design with a strong focus on sustainability and net zero energy solutions. Headquartered in Louisville, Kentucky—with additional offices across several states—CMTA delivers mechanical, electrical, plumbing (MEP) engineering services alongside comprehensive energy savings performance contracts to public sector clients such as K–12 schools, higher education institutions, healthcare facilities, and government buildings.
The company is an industry leader in designing net zero energy buildings; its portfolio includes pioneering projects like the first WELL Gold Certified Zero Energy corporate headquarters in the United States. CMTA’s “reduce-before-produce” philosophy emphasizes maximizing efficiency through upgrades such as lighting retrofits and geothermal HVAC before integrating renewable technologies like solar photovoltaics to offset remaining consumption.
With over 16 million square feet of operational zero energy/zero carbon projects nationwide—and more than $100 million delivered in utility savings—CMTA leverages decades of real-world data analytics to inform its holistic approach to decarbonizing the built environment. The firm recently expanded its expertise by merging with AMA Group under Legence ownership, further strengthening its capabilities across acoustics and immersive technology design.
Notable achievements include delivering Indiana’s first two net zero schools via rooftop/ground-mount solar installations combined with deep efficiency retrofits—a testament to CMTA’s leadership at the intersection of innovation and environmental stewardship.
