Ameresco and Mount Sinai School District partner on a comprehensive energy infrastructure project across three schools, modernizing aging facilities, reducing operating costs, and creating new STEM learning opportunities for students.

The project, valued at over $10M, includes full LED lighting replacements, upgraded energy management systems with direct digital controls, replacement of existing transformers with high-efficiency transformers, rooftop solar PV arrays at each school, and a fuel oil to natural gas conversion at the district’s elementary school. Structured as an energy performance contract, the project began in May 2026 and is targeted for completion by the end of 2027.

“This partnership reflects the Mount Sinai School District’s ongoing commitment to maintaining safe, efficient, and modern learning environments for our students while being responsible stewards of taxpayer resources,” said Dr. Christine Criscione, Superintendent of Schools. “Through these upgrades, we are investing in our facilities, improving operational efficiency, and creating opportunities for students to connect with real-world energy and sustainability initiatives for years to come.”

Key outcomes of the project include:

  • Updated energy infrastructure across three schools on the north shore of Long Island, addressing outdated systems, cutting long-term operating costs, and reducing greenhouse gas emissions

  • Significant expected savings over the project term, calculated according to New York State Education Department guidelines, supporting the district’s financial and operational goals

  • STEM programming, giving technology teachers and students hands-on experience with live energy data from the installed systems, while also exposing students to career opportunities in both engineering and the installation trades

“Mount Sinai School District is taking a thorough approach to energy infrastructure that will benefit its students and community for decades,” said Louis Maltezos, Co-President of Ameresco. “By blending operational upgrades with educational components, this project creates real, lasting value in the classroom and throughout the district’s facilities.”
