The availability of hyper-heating was really important given the rough northeast winters. We also like the track record of performance and reliability with Mitsubishi [Electric], and their extensive service network relative to other manufacturers.

The Hollis Montessori School (Hollis Montessori), Hollis, New Hampshire, is the first independent school in the country to receive Passive House certification. This certification denotes the school’s extreme energy efficiency and means the facility has met rigorous energy-saving standards. A Hyper-Heating INVERTER™ system from Mitsubishi Electric makes such efficiency possible. The system also bolsters indoor air quality throughout the year – even in the rough northeast winters. The result? Hollis Montessori is consuming 85 percent less energy than other schools and its students are excited to learn about these savings. Download the PDF below to read more. You’ll hear from the school board, architect and energy consultant, and see photos of the equipment and school.
