J.W. Killam Elementary School

CES is providing mechanical and electrical engineering services for a new, state-of-the-art elementary school designed to set a benchmark for energy performance and sustainability in the region. This all-electric, fossil fuel-free facility is targeting LEED Gold and designed to be Net Zero Energy Ready, aligning with the town’s ambitious environmental goals.

To support these goals, our team conducted a comprehensive review of multiple system strategies in close coordination with the client and design team, ultimately developing a highly efficient solution centered around a geothermal system and innovative building technologies. The design features an estimated 45 geothermal wells, each approximately 800 feet deep, paired with ground-source heat pump chillers and chilled beams to minimize energy use. Dedicated outdoor air systems (DOAS) and rooftop units provide ventilation with energy recovery and support natural ventilation strategies where possible.

Additional features include a rooftop solar PV array (~160 kW), 10-15 planned electric vehicle charging stations, and a generator for critical systems. The building is designed with resilience in mind, raised approximately 15 feet above grade on structural columns due to its location in a flood zone. A three-story open atrium and media center anchors the interior.
The project is currently tracking on budget and targeting an ultra-low EUI of 21, making it one of the most energy-efficient schools in the state.
