1st Step To A Better Building With Passive House

The energy retrofit to my California Ranch-style home was not about energy savings as much as it was about comfort through a better building. While the house has always been nice and cool in the summer it also has been cold in winter. 

With one wall unit mini-split heating source in the front of the home the bed- and bathrooms in the back where always uncomfortably cold. No bath towel would really dry in those damp and cold bathrooms.

Instead of mindlessly adding heating in the back I wanted to find a superior solution that did not involve fossil fuel operation.   

I used the Passive House Standard to guide the first step of an energy retrofit to create a better building. 

The Passive House Standard provides a guide to retrofits and remodels as well. This first step to a better building involved the following upgrades:

  1. Airseal all walls
  2. Add exterior continuous insulation
  3. Add heat recovery ventilation system    

All products were purchased through a company that focuses on high performance building materials: 475 High Performance Building Supplies.

Browse thru my picture book about the first step of the deep energy retrofit I did for my 1964 Ranch style home below. 

Already applying the liquid airtight membrane made a significant difference inside. You can see where the membrane was applied (blue) and you can also see where it is already dry (black).

The retrofit was done during a California winter, an actual cold and rainy winter. The perfect, on the spot test of all the measures we installed.
