PHPP vs. Title 24 – Windows

The most thermally-inefficient parts of a high-performance residential building are the windows. The insulating values are usually in the range of R-3/inch (typical) to R-10/inch (very high-quality). When compared to typical wall insulation of R-21/inch, thermal movement is going to take the path of least resistance—the windows. Even more importantly, if you want to realistically understand how a building component performs, you need to accurately evaluate it. Passive House windows…

Today, the Passive House standard has been implemented throughout the world and shines particularly brightly in beacon projects globally. More reasons for celebrating:…


Is Cost the Barrier to Passive House Performance

A new NAPHN report by Bronwyn Barry, NAPHN Board Chair, looks at cost assumptions, barriers, and the reality of cost in achieving Passive House buildings. “Most non-profit developers we work with are all passionately seeking ways to build better for less. In our advocacy work at NAPHN, we’ve found that these developers are most concerned with two things: first cost to build, and operating costs for their occupants. Of these…

Passive House Residential Ventilation in California

Passive House residential ventilation seems like a fairly straightforward topic on the surface. You install a whole-house heat-recovery ventilator (HRV) or energy-recovery ventilator (ERV), exhausting stale air from the wet areas of the house and supplying fresh air to the primary living and sleeping areas. (I’ll use the term HRV to represent both types of equipment throughout the remainder of this article). Unfortunately, the Passive House design guidelines don’t always…
