Some readers at Treehugger didn’t quite take the hint (and didn’t know what NSFW means), so let me spell it out ahead of time: this post is naughty. If you’re at work, hanging out with your mum, or just can’t handle a bit of lascivious innuendo, don’t click play on the video embedded below. If you’re not averse to a bit (honestly, just a bit) of ribald fun, click away, because this really is one of the cutest explanations of passive home construction I’ve seen. And as they say, sex sells.
The video comes by way of La Plate-forme Maison Passive, an association active in French-speaking areas of Belgium whose goal is to promote passive home design and construction: better insulation, airtight construction, solar gain heating, triple-pane windows, heat-recovery ventilation systems, and all of the other myriad ways of conserving energy and money with smart building practices.
As the video so deftly points out, unlike many green home innovations — which save money in the long run, not to mention reduce our impact on the environment, but can carry a hefty price tag at first — the upfront cost of passive home design really isn’t all that significant? How significant? Well, as with most things in life, size matters.
