“We think it’s a great match between affordability and energy savings,” Slater said.

Passive houses don’t come cheap, though, which presents a challenge for Habitat. Slater estimates that a passive house costs about 20 percent more to build than a typical house.

 “We have to fundraise the extra cost of the passive house,” she said. “We still sell below what it costs us to build, but it can’t be that much lower.”
