HABITAT PASSIVE TOWNHOUSES
Columbia County Habitat for Humanity has constructed two affordable townhouses in Hudson, New York, aligned with the Passive House standard.
The Habitat Passive Townhouses are the first Habitat townhouses in New York to utilize the Passive House Standard which results in an estimated 90% less energy for heating.
Envelope. Columbia County Habitat for Humanity has constructed two affordable townhouses in Hudson, New York, targeting the Passive House standard. The air-tight, super insulated homes feature 12" R-43 cellulose double stud walls and an R-87 roof, together with an R-56 foundation slab using 12" of EPS foam, and U-0.15 highly-insulative, triple-paned windows.
Systems. The heating and hot water are provided by a high efficiency natural gas condensing boiler, and ventilation by an 84% efficient HRV.
