Progress continues at our Passive House Project! The Contemporary trim package is almost complete!
After insulating the house (but prior to drywall installation) our second blower door test was conducted, with a result of .37 @ 50 pascal. This is an incredible result that will significantly improve the energy performance (and comfort) of this home!
The "Butterfly Roof System" is designed to collect and treat rain water to supply our Passive House with fresh water.
There are different ways of achieving energy efficiency in a house. The passive house and net zero approaches are two of the best, as a passive house uses very little energy and a net zero house produces as much energy as it consumes.
Despite the harsh winter conditions (2 major storms in 1 week!), the second floor is complete and our Passive House is ready for the roof structure.
