This multifamily building boasts ultra-low energy use because it’s built to Passive House construction standards. Lower energy consumption results in lower monthly costs for the owner and residents. Measures like continuous air sealing and insulation help to regulate temperature and air quality, while also controlling odor and noise in each unit. These features maximize safety, comfort and affordability for residents, as well as improve the project’s bottom line. This property spends substantially less on gas heating and hot water than a conventional property, thanks to its super-insulated, airtight envelope, energy recovery ventilation, and solar thermal water heating system. The low heating load of the building also meant smaller (and less expensive) boilers could be installed, which helped to keep construction costs down.
