Jeff and I are at the Passive House training. Things are going well. Cool geeks, incredibly stringent performance standard. Today, we were looking at an assembly that included an R-40 wall (12 inch TJI studs with cellulose, OSB on both sides, then another insulated 2×4 stud wall), R-75 subslab insulation, and R-10 perimeter insulation. In this configuration, an uninsulated bottom plate created a thermal bridge that wasted 8% of the available heating load for the entire building under the Passive House standard. Yikes!
Anyway, it’s not all hard work. For fun Jeff is testing the pH of Coca-Cola in the hotel. (That’s pH… not PH for Passive House. Get with the program!) According to Jeff this was necessitated because they have been planning on stepping up to kegs for Kombucha. The keg guy thought the acid levels in Kombucha would corrode the kegs. They’re made for Coke, so if that shit has a similar pH to Buchi, then the kegs will survive.
Internal Nauhaus Institute memo: By the way, Scobie didn’t make the label. They’re going all high brow looking for she-she crowd or somethin’. Scobie Lives!!
Anyway, here are the Coke study results:
