Bethesda Passive House

The system does the job without you noticing it too much, which is really nice. It’s also quiet outside; we hear our neighbor’s system from three houses down more than we hear ours.

The Washington, D.C. area’s first certified Passive House is extremely energy-efficient and high-end. It also features a multi-zone heat pump from Mitsubishi Electric, selected because it could stand up to D.C.’s cooling-dominant climate and Passive House’s rigorous energy-efficiency needs. The result: cooling and heating for just $57 a month – one-fifth of the area average! Download the PDF below to read more . You’ll hear from the homeowner, architect and contractor, and see a photo of the house.
