Passive House California at COP26

It should not be a surprise that the International Passive House Association (iPHA) was well represented at the recent COP26 in Glasgow. Four years earlier at the 2017 North American Passive House Network conference, UN Deputy Secretary-General Amina J. Mohammad described Passive House as “a model for the developing… and the developed world.” (Originally published on the EcoReport 2017) iPHA was involved in COP26 in several ways, including a tour…


PHPP vs. Title 24 – Thermal Bridging

Thermal bridging is a complicated topic for two reasons: it has multiple aspects, and it often requires complex calculations. Let’s look at a simple case first—exterior wall framing. An exterior wall has multiple layers. For instance, from outside to inside, it may have: Stucco or some type of siding An air gap or rain screen designed to help drain bulk water A bulk water barrier Sheathing, typically ½” plywood or…


EpiPHany Corner | How is a Passive House building like a glider?

The wings of an airplane are designed to provide lift when pushed or pulled through the air at sufficient speed. The wing itself can be considered a “passive” element because it is the design and shape that enables it to produce lift whenever the airplane moves through the air. As long as the airplane maintains sufficient airspeed the wing will deliver lift and the aircraft will fly. When an airplane…

PHPP vs. Title 24: Shading Analysis

One critical aspect of building performance is shading. With a properly designed building shell, the amount of solar radiation hitting the building’s opaque surfaces usually aren’t a problem. However, the windows are the weakest link in the shell. The presence or absence of shading can have a huge impact on cooling and heating loads, even with excellent quality windows. You can control radiation intrusion to a certain extent by tuning…


EpiPHany Corner | Do Pass/Fail choices deliver optimum performance?

Even though it seems intuitively obvious that the logical answer is NO, a surprisingly high percentage of decisions regarding the design and construction of new homes are made on a Pass/Fail basis. “Building to code”, means complying with at least the minimum acceptable requirements in the large number of specific areas where compliance is required. Code is a Pass/Fail system and if a building does not meet one or more…
