We received precertification status with Passive House U.S., or PHIUS last month. This is our first project with PHIUS and we are all excited for the challenge ahead. It will include a super insulated airtight envelope (0.6ACH50), continuous mechanical ventilation via a high efficiency ERV, rigorous control of solar gain, high performance windows, and a composting toilet. We can also tap into our existing solar thermal hot water system to reduce the energy demand for water heating. We spent a lot of time developing our design and energy model: now it's time to build it!

As the smallest Passive House U.S. project currently in precertification status, we have our work cut out for us!
