Hollis Montessori Goes Net Positive

First Certified Passive House Elementary School in the U.S.

The Hollis Montessori School celebrated their tenth anniversary with a transition to renewable energy. As the first Certified Passive House elementary school in the U.S., the building already has an exceptionally efficient enclosure paired with high performance systems (for heating, cooling, hot water, lighting, and ventilation). The new installation of a 56.8 kW photovoltaic system completes the vision developed by the board of directors. The system is expected to offset all the energy demand of the high-performance building, with extra energy available for use for the other buildings on the school campus. The building is now net positive energy, and contributing to the goal of net zero energy for the entire campus.

ZED provided Passive House Consulting and Mechanical Design for the project.
