Solar Retrofit - Part 3: Looking for Installation Help

As mentioned in my previous posts, I've signed a contract with Taylor Munro Energy Systems from BC for a solar thermal system to help provide space heat and domestic hot water.  My contract is for system design and
major component supply - it does not include installation.

I wonder if anyone familiar with the solar industry in Edmonton could put me in touch with local installers that could help me get my collectors installed on my house.  This is the proposed south elevation:

MCNZH - Progress (part 2) - more framing, wood reuse

We have trusses, and we'll have a roof by tomorrow. Nick and Adam of Green Door Builders are doing a great job of framing the house. Peter is always amazed at how little waste they create. They're only throwing out little toothpicks of plywood. On top of that they are dipping into a pile of reusable lumber that I set aside for them:

A 2x6 left behind by the cribbing crew (up top, covered with a light coating of concrete) was conscientiously reused during framing  read more... »

Solar Electric System - Actual Performance

The Riverdale NetZero Project, one of twelve projects to emerge from CMHC's EQuilibrium Housing Initiative, is now complete. It is a groundbreaking project that is the result of many people putting in many volunteer hours. It looks like the duplexes will each actually be NetCredit homes, because their performance is exceeding expectations so far.  read more... »

Heating System

I've thought about the heating system for the Mill Creek NetZero Home (MCNZH) for months now. The home will need a very tiny amount of heat because it's so superinsulated, super sealed, and passize solarized. The computer model that simulates the energy performance of the house (using HOT2000) has the MCNZH using 2500 kWh. That's roughly 6% of the heat that my renovated (with new insulation and windows) 1950s bungalow uses.  read more... »
