The new 205,000-square-foot Nashoba Regional High School will exemplify next-generation sustainable design. CES is providing mechanical, electrical, plumbing, and geothermal engineering design to create a fully electrified, fossil fuel-free facility that will set a new benchmark for high-performance learning environments.
At the heart of the project will be an advanced geothermal heating and cooling system, consisting of 72 bores each 800 feet deep, configured in a quad loop system to support the entire building’s thermal loads. Classrooms will feature chilled beams with ventilation from Dedicated Outdoor Air Systems (DOAS) to deliver energy-efficient comfort. Despite limited site space, careful early coordination has allowed the geothermal field to be installed ahead of construction, ensuring a seamless transition to building completion.
Targeting Net Zero Ready performance, the school is expected to achieve an impressive EUI of 27 kBtu/sf/year, integrating energy recovery, a high-performance envelope, EV charging, and generator backup—demonstrating the district’s commitment to sustainability and innovation.
