Ave Maria University Campus

In the first phase, Ameresco implemented a new building automation system (BAS) that integrates HVAC equipment across five campus buildings. The web-based platform has already improved occupant comfort and operational controls, with projected annual savings of approximately $200,000. As part of the University’s broader strategy to modernize campus infrastructure, the second phase addressed exterior lighting, resulting in improved visibility and safety.

“As our campus continues to grow, we knew we needed to invest in infrastructure that could keep pace—not just for today, but for the future,” said Paul Husak, Chief Operating Officer at Ave Maria University. “In doing so, we’re living out our responsibility as an authentically Catholic university: to steward our resources wisely, safeguard our students, and prepare a campus where future leaders and future saints can flourish.”

To further support Ave Maria’s expansion goals, Ameresco developed a project to increase the central utility plant’s capacity by more than 80%. The upcoming third phase will add a 3,000-ton chiller to the plant, boosting total capacity from 3,600 tons to 6,600 tons. This upgrade will ensure system redundancy and improved efficiency across the University’s 17 facilities. Construction is expected to be completed in 2026.

“This design-build project with Ave Maria University exemplifies how thoughtful energy infrastructure planning can unlock long-term value,” said Lou Maltezos, President of Central & Western USA, Canada Regions at Ameresco. “By integrating advanced building automation and expanding central plant capacity, we’re helping Ave Maria University create a safer, more efficient, and future-ready campus that supports its academic mission and long-term vision.”

The collaboration between Ameresco and Ave Maria University reflects a shared commitment to leverage innovative energy infrastructure to support their long-term academic needs and energy goals. Aligned with the University’s strategic growth plans, this project is delivering measurable benefits today while laying a resilient foundation to meet the evolving needs of its students in the future.
