Passive buildings maintain a comfortable interior climate without large heating and cooling systems — that means no more radiators or air-conditioning units for these homes. This is done using, among other things, an airtight building envelope, and a system that exchanges interior and exterior air, usually an energy recovery ventilator.

Besides lower energy bills, benefits include quiet interiors because of thick, insulated walls, along with fresher, cleaner air, thanks to the filters in energy recovery ventilators. Builders and residents of passive houses say the filters can help eliminate allergies and asthmatic symptoms.
