In my last posting about the Code Minimum House, I talked about how the foundation was constructed. Next up, the framing. This home is being built with a small budget. To keep costs in line, Continue reading “Construction Design-Code Minimum House-Framing”

Energy Audit-Comparing a Great Blower Door Test to a Code Minimum Test
I recently blower door tested the tightest new home I have tested to date. .82 air changes per hour at 50 pascals (ACH50), nearly one-quarter of the code required 3 ACH50 requirement. After the test, the builder and I decided to open a window to see how much additional leakage it would take to get the home to the code minimum 3.

Construction Design-Simple Air Sealing Strategies

Construction Design-Interior Air Barrier? Exterior Air Barrier? Or Both!
When designing the concrete-less slab on grade home, I gave serious thought to the location of the air barrier. I have used water resistive barrier (WRB) or house wraps for years without a good understanding how they work as an air barrier. In my climate, most homes use polyethylene sheeting as an interior (and main) air barrier. As it turns out, there are better choices. Continue reading “Construction Design-Interior Air Barrier? Exterior Air Barrier? Or Both!”
Building Science-Stack Effect
I’ve talked about the stack effect several times on this blog, but have never written a post dedicated to the subject. Stack effect is present in every home. Older, less air sealed homes (like mine) will usually have a more air exchanges due to stack effect. Continue reading “Building Science-Stack Effect”

Construction Design-Fixing Ice Dams from the Interior, Part 2
This past winter has been one of the snowiest and coldest I can remember in my 50 years living in Minnesota. I wasn’t completely sure what to expect from the home I purchased late last fall. I know it has issues, especially with the roof air sealing and insulation. Continue reading “Construction Design-Fixing Ice Dams from the Interior, Part 2”
My Cape-Office Build-Out
We moved into my 1952 Cape last December. Winter was upon us, no time or desire to start any of the major renovation and energy updates I have planned. My office was moved temporarily into the extra basement bedroom with a plan to build-out a new office adjacent to the bedroom. Continue reading “My Cape-Office Build-Out”
