This is a blog about building a Passive House in Flatrock, Newfoundland. We'll discuss decisions, and challenges, and follow the progress of the build. As it stands, this will be the first performance house built to the PHIUS standard in Newfoundland. The total energy requirements will be 7300 kWh/year and 3/4 of a cord of firewood. It will be the most energy efficient home in the province. CONSTRUCTION HAS STARTED!!!
Lets Try This Again: A Well Insulated Slab
Time was ticking and we ran out of 2" type II EPS. Luckily our local building suppliers carry a small supply of 2" 2'x8' Foundation Plus. The next morning we finished up placing the foam. Pipe and conduit penetrations in the foam were cut slightly oversized to allow some room for aligning the foam pieces together. After the foam was laid, we spray foamed around the pipes (Photo 1-1). This serves 2 purposes: The first is to insulate, the second is to stabilize the pipes during the cement pour.
On to the next task: Vapour barrier, air sealing, and rebar!
