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…


EpiPHany Corner | PH Envelope Elevates the Impact of other Efficiency Measures

Passive House protocols, when applied to the design and construction of a building, will dramatically reduce the energy required for heating and cooling. This reduced energy for heating and cooling lowers the overall energy use significantly. As a result, the amount of energy used for water heating, lighting, refrigeration, appliances/electronics (plug loads) become more impactful and more important to manage. Consider the example below.  The Pie Chart on the left…
