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.
- Airseal all walls
- Add exterior continuous insulation
- 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.
