Conducted in two phases, the project delivered district-wide upgrades to mechanical systems, lighting, and building envelopes to enhance weatherization. The first phase replaced outdated equipment at the elementary and high schools with high-efficiency heat pumps, modernized HVAC in classrooms and offices, upgraded LED lighting, improved gymnasium air circulation, and added air sealing and insulation to reduce energy use and optimize indoor conditions.
Phase 2 focused on the junior high and additional learning spaces, replacing aging fuel-oil and propane systems with efficient heat pumps and upgraded temperature controls. Programmable thermostats, demand-controlled ventilation, and economizer functions were also implemented to improve energy efficiency and indoor air quality, as well as supplemental electric heating to ensure consistent conditions throughout the buildings.
The comprehensive improvements are projected to generate over $93,000 in annual contracted energy savings, strengthening operational performance and long-term reliability.
“This project reflects Charlo School District’s commitment to providing safe, comfortable, and efficient learning environments for our students and staff,” said Jim Baldwin, Superintendent at Charlo School District. “By modernizing critical energy infrastructure across our schools and eliminating fossil fuel burning equipment, we’re advancing our sustainability goals, improving day-to-day comfort, and enabling resources to be directed where they matter most: in the classroom.”
The project builds on Ameresco’s ongoing work across Montana and its commitment to enhancing energy efficiency for K-12 districts nationwide. Phase 2 received partial support from a Renew America’s Schools grant, enabling the district to expand upgrades and accelerate the replacement of aging systems.
“We are proud to partner with Charlo School District to modernize energy infrastructure and deliver measurable cost-savings,” said Lou Maltezos, President, Central & Western USA and Canada Regions at Ameresco. “Through this collaboration, the district is improving energy efficiency, strengthening facility performance in ways that will benefit students and staff for years to come.”
