If I understand your question correctly, we constructed a net zero project that produced as much energy as it consumed. Further to your question of whether it is affordable, we have feed-through tariffs here in Ontario, so putting photovoltaic cells up on the roof pays somewhere between 40 cents and 80 cents a kilowatt-hour, an astronomical sum of money, which makes the project a bit more affordable for people to use.
Overall, I would say that you can build a single family home that is tighter and more efficient, using way less natural resources, from wood to energy to electricity to water, and have it as a wonderful example of why you should buy, but unfortunately, the price goes up and it becomes a more expensive home. Your overall operating cost as a homeowner is lower, your mortgage cost is a little bit higher, and your expenditures are way lower, so you wind up with an overall affordable situation. Your cashflow is always positive, but your home price goes up.
The consumer today looks at that first home cost and says, “Oh, I don't want to pay that much money”. The federal government looks at first home costs, where the GST rebate comes in at $400,000, and for anything below that, you're okay. If I add $100,000 to the home, a $325,000 home now has GST applied to it. That's all because of renewable energies that are being put on the roof and because of having a better and efficient home. It's a more cost-effective solution for the homeowner, but they have to pay GST and all these other things because now it's an expensive home. It doesn't make sense.
We really need to see a way to say that renewable energies and energy efficiency should be excluded from the price of the home. The consumer really needs to understand that. I think that's where we can all start delivering a better message. It's the cost of home ownership that's important; it's your mortgage cost and your utility costs that add up to what a home price is, not $300,000 or $400,000.
Overall, yes, it's very affordable. Yes, it's great for the environment. But we have bad marketing and bad education out there from the entire community and we need to do better at that.
