MCNZH - Flex House (Part 2)

MCNZH, Second Floor. As built on the left, and "flexing" on the right.

Durability is absolutely key to sustainability. Everything we buy, every precious drop of fossil fuel that we burn, should be put to best use by creating as much value from it for as long as possible.

I see no reason why the Mill Creek NetZero Home (MCNZH) can't stand for hundreds of years. To be as useful as possible during its long lifetime, we designed it to flex with the changing needs of its occupants.  read more... »

Solar Retrofit - Part 4: High Efficiency Heating & Domestic Hot Water

My previous post regarding the problems with Taylor Munro Energy Systems was very negative.  While the problems with TMES are still not resolved, I'd like to focus this posting on a part of my renovation that worked really well:  The high efficency boiler and the heating system.  

There are three main components to the system: 1) a source of heat: the boiler, 2) something to replace my furnace: a fan coil and 3) a domestic hot water (DHW) tank that runs off the boiler.  In addition, I've done a retrofit of radiant floor heating.  This step is optional and was done to allow zone heating of different areas of the house.

Insulated Basement Slab

The best two things a home builder/renovator can do in the name of energy efficiency is to insulate and seal a house. It's almost too bad, what with our culture's obsession with everything high tech. When people ask me about the Mill Creek NetZero Home (MCNZH), they're often expecting to hear about technology's magic answers. When I start talking about insulation levels, eyes start to glaze over, but the truth is that 75% of the difference between this house and a conventional one is that it's sealed as tight as a plastic bag and it's super-insulated.  read more... »

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:
