It’s good for the climate! And for us!

Passive House Institute points way to climate-friendly buildings. The topic of energy efficiency is often woefully neglected in discussions on climate protection. However, buildings-related emissions can only be significantly reduced by consuming less energy for heating and cooling. The Passive House Institute presents its proposed solutions for a climate-friendly building stock in three “building blocks”: A substantially higher level of energy efficiency of buildings; on-site generation of renewable energy; and a…

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…

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…
