Green Homes Tour

We were invited to take part in the County Sustainability Group's Green Homes Tour this year, which forms part of the Quinte Sustainable Living Symposium event this weekend. Three bus parties turned up today (in wet and miserable weather, unfortunately) to get a tour of the solar hot water and geothermal systems in our basement, followed by a look at the greenhouse and at the solar panel set-up in the barn.

It was fantastic to meet so many people with similar interests to ours and Mike did a great job of transmitting his enthusiasm for the green energy projects that we've been undertaking over the last two years. There were a lot of pertinent questions and some good ideas for making the best use of the greenhouse and barns.

One thing that came up which we hadn't heard about before was a concern about using the rainwater from the house roof as drinking water, as the roof has asphalt shingles on it. People in two different groups mentioned that the asphalt can leach out unpleasant chemicals (including oestrogen-like ones) into the water. We hadn't come across this potential problem, so immediately turned to the Internet for answers when the last bus had gone. It turns out that the best way of ensuring that oestrogens are removed from water is to use a reverse osmosis system. Which is what we have, so that's quite a relief!

I so wanted to come too! Sadly, living on a completely different continent made that impossible. Sounds completelty fascinating and I'm glad to hear it went well (despite the weather.)
