The goals of this project were operational Net Zero, electrification & solar PV, and preferred use of sustainable/recyclable insulation material. The project is nearing completion and has started consumption monitoring as of December 1.
Phase 1 consisted of attic & roof improvements. Existing insulation, 2 chimneys, 2 bath fan vents, & the main plumbing stack penetrations were removed, all leaks were manually sealed. Shingles were replaced and the perimeter attic/wall air barrier connection made with sprayfoam prior to blown in cellulose installation.
Phase 2 was removal of natural gas appliances and installation of heat pump & fan coil, ERV, heat pump hot water tank & dryer, electric induction range & fireplace (& garage heat pump). Gas meter was removed, and electrical service masts moved to garage and upgraded to 200amps available on local transformer.
Phase 3 started with removal of exterior vinyl, poor foam insulation, stucco, siding, and original windows. 8" site built "Larsen" wall installed with 2x2, plywood girts, and exterior plumbed 2x2 prior to installation of new windows & doors. After mesh & cellulose install, Typar AWB was installed & tape sealed, and walls were strapped for install of vertical corrugated metal siding.

Siding will be installed December/January, and solar PV early February - hopefully in conjunction with the release of Calgary's CEIP property tax based loan program. Air quality, electrical consumption, and solar production will all be monitored ongoing with data provided to SSRIA and SAIT for educational purposes.
