Define Sustainable Building
I'm in a bit of a quandary. Since moving into our Irish farmhouse two years ago we have renovated it slowly and now we are at a crucial stage of decision making. Living sustainably is something we try our best to do in all aspects of life. Its all very well knowing the buzzwords but there's still a lot of ambiguity when it comes to applying those definitions to the reality of everyday situations.
We want to build an extension. Or at least I think we do. It all began with the simple and innocent thought that we'd love to have a sun room or conservatory to sit in during sunny days, even in winter. We began to think about how we could apply sustainable principles to this new venture ... perhaps we could use passive solar gain from a sun room to heat the rest of the house? With this initial thought we had unwittingly opened up a pandoras box. Do we go down the architect route and get something really very special in appearance, high tech in energy efficiency performance which would reduce our lifetimes energy consumption and score high on Irelands new Building Energy Rating scheme. The architect could solve some basic household problems while we're at it by designing something that would give us a bathroom upstairs and a toilet downstairs ... at present there is only a single bathroom/toilet which is downstairs. This plan is very attractive yet extremely expensive coming in at around €100,000 and involving the upheaval of probably the best part of a year in a mobile home on site while the work is being carried out, plus the sale of my late mothers house to fund the project.
But there is another approach to building sustainably. Why spend such a huge amount of money to get a toilet upstairs? Is it worth the investment just to avoid a trip downstairs to the toilet at night every so often, is it ridiculous to even consider such a payout? But its not just the toilet, there's the sun room. Couldn't we build a little sun room ourselves for a tenth of the cost? Would using natural local materials be a far more efficient approach, efficient in terms of production and transport of the materials, but then again not so good in terms of long term fuel savings? That is the million dollar question. Its a question that Peter Cowman of the Living Architecture Centre asked himself and now offers solutions to those who wish to design and build their own living space, mortgage free, with local materials. Funnily enough, he lives just down the road from us.
The quandary ... high tech high spec heat insulating materials that have high energy costs in their production or lower efficiency local eco friendly materials on a small scale. Perhaps the pros and cons of each individual project need to be considered. What do you think?
