There was this idea circulating in the last years that super energy-efficient homes are very expensive to build compared to typical code-level energy homes. Is this still valid? Is is possible to build a Passive House nowadays on a reasonable budget?
In the US, typical costs of a passive house vary between $175 and $200 per square foot (approximately $1880 to $2150 per square meter), but architect Richard Pedranti managed to design a home to Passive House standards for only $165 per square foot ($1776 per square meter). The house called Scranton Passive House was built in 2015 in Scranton, Pennsylvania and got the Passive House of the Year award in 2017. Mr. Pedranti was kind enough to also create a free e-book containing lots of details about the house.
