In the span of just five years, a lot can change. We became involved in , a local demonstration passive house project in 2015, and at that time there was little to no recognition of what this 'green' standard was or why it was remotely relevant to promote it in our rural northern region. ⠀
⠀
We often think of transportation (cars & flying) as being the biggest/baddest use of fuel in our lives, but reducing the operational emissions (heating & cooling) from the buildings that we live, work and learn in everyday - is an equally important tool in addressing the climate emergency.⠀
⠀
Why are buildings that meet the passive house standard considered 'green?' Essentially, they are houses wearing weather appropriate coats - in Canada's North where I live, that means they have a building envelope (walls & roof) that act like a warm winter jacket. (Passive houses work in hot climates too... but I don't live there!)⠀
⠀
If you live where its usually cold, by keeping the heat inside and taking advantage of south facing sunshine to help warm your building up - passive houses don't require much energy to heat. They can reduce energy consumption for heating by as much as 90%, and no matter the source of that energy, that's a potential 90% savings in your heating bills!⠀
⠀
But lets say your heating energy comes from a fossil fuel source such a gas, diesel, coal, etc - in that case, it also amounts to a 90% reduction in the green house gases emitted into the atmosphere from your home or the building you work in. We spend most of our waking lives in some type of building, so we should ensure those buildings achieve meaningful GHG reductions like the passive house standard can!⠀
