About
The project was a replacement of an elementary school in Lexington, MA. The existing building was demolished after the new building was constructed. The new 110,000 SF school serves 645 students, 111 full-time employees and 7 part-time employees. The all-electric building features Ground Source Heat Pumps, a rooftop PV array and parking lot canopy system, and onsite battery storage. The building's operational EUI is 23.4. For 2022 and 2023 the building's average consumption was 18% less than projected, therefore the building is operating net energy positive by 37%.
