The Passive House Build: Getting the Mechanicals Right
A carefully designed mechanical system rounds out this house’s heating and cooling load.
Synopsis: Although a Passive House is designed and built to be heated primarily by the energy from sunlight, there is almost always a secondary source of heating. Architect Steve Baczek explains the choices that were made in this energy-efficient home in Cape Cod—from the reason he chose a ductless minisplit heat pump, to his experimental plan of using the house’s energy-recovery ventilator (ERV) not only to bring in fresh air but to circulate the conditioned air from the single minisplit.

Although many superinsulated houses are designed and built to be heated primarily by the energy from sunlight, there is almost always a secondary source of heating. The house shown here, which was covered in a recent series of five articles and videos, is no exception. It receives 50% of its total required heating from the sun — with another 25% from…
