Leader in EnergyEfficient K-12 Design
CMTA has been engineering K-12 facilities for more than 50 years and understands how buildings affect students’ success, health and wellness. We recognize that a building does more than house its occupants, it must promote student success by enhancing their comfort and health. This is accomplished through our attention to air quality, temperature, natural daylighting, reducing energy consumption, and WELL principles. We strive to supply school districts with the best systems for their buildings and users, while keeping operating costs low.
In addition to design, our leaders serve on technical and standards committees and regularly contribute to the development of the handbook and national high-performance building standards. In fact, we helped author ASHRAE’s “Advanced Energy Design Guide for K-12 School Buildings – Achieving Zero Energy.” Three out of six schools featured in the guide were designed by CMTA.

Our process explores other emerging technologies to facilitate teaching practices and student learning experiences and assist with the development of departmental policies and procedures, planning, budgeting, and priorities.
STEM Curriculum Integration
In the early 2000s, CMTA began using the buildings as a teaching tool, pulling back the curtain on building systems so staff and students alike could understand the effect of systems on performance. Watching our students lead tours of their high-performance buildings and listening to them explain the systems, and observing the interactions between the building and its occupants inspired our team of building science leaders.
Having pioneered some of the most student-oriented, interactive learning dashboards ever implemented, CMTA was not content to rest. As a result, our team of building scientists are once again ahead of the curve with CMTA SPHERE.
CMTA SPHERE combines the latest in immersive technology with virtual reality customized to a particular facility. Each SPHERE system is unique, designed to reinforce a project’s particular educational goals, and aligns with STEM goals that drive future success.
Buckley Elementary School
Manchester Public Schools | Manchester, Connecticut
Buckley Elementary is the State of Connecticut’s first verified Net Zero Energy K-12 school and the first verified publicly funded net zero K-12 project in New England. Constructed in 1952, the building underwent an extensive renovation focused on sustainability, energy efficiency, and an improved learning environment.
CMTA began the project by creating an energy model and studying all features of the building envelope, including walls, windows, and roof systems. As the existing building was ideally situated in a north/south arrangement, its orientation remained unchanged for optimal glare control and daylighting. The project also included a whole-building blower-door pressure test to validate tightness of construction as well as thermal scanning/ imaging. The goal was to have a wellinsulated building that exceeds code minimum requirements and was also air/ water tight.
Led by CMTA, all mechanical systems were designed to drastically exceed code minimum. High-efficient geothermal technology is used to heat and cool the building, with the geothermal wellfield acting as a thermal battery for heat storage. The project successfully implemented an all-electric design, including introducing air conditioning, electric kitchen equipment, and ventilation, and still saved the school district over $50,000 in their electric bills in the first year. A 390 kW roof-mounted solar array generates enough energy annually to meet all the building’s energy demands.
