It might not be great weather for the bank holiday but there’s a silver lining from where I sit. It’s filling up the rain water harvesting tank. Now it’s all up and running and working as it should we are happily flushing the toilets with rainwater. In the event of a drought (you never know) or power cut the tank reverts to being fed by the mains water.The tank, pump and controls were supplied by Envireau (http://www.envireau.co.uk/).
Here’s a link to a recent article about the house by Tony McIntyre for Building Design magazine.Enjoy. http://www.bdonline.co.uk/story.asp?sectioncode=428&storycode=3106739
Yesterday I braved the eco warrior hoards and went down to Ecobuild at Earls Court (www.ecobuild.co.uk). Blimey what a scrum. Clearly there’s something in the water as it seems everyone is either creating something to sell as Eco or else busily looking around for the next, new Low Carbon widget. I particularly loved the air conditioning manufacturers being there. Next year you’ll be able to win a hybrid 4×4 I expect. I guess it’s encouraging that so many companies feel that there’s money in being green but it did seem a bit desperate. There was still a crazy amount of paper being given away that even the recycling bins at the side would never cope with. I would like to know the full Carbon Footprint of Ecobuild, including making and bringing in all the stands, food, visitors etc. Has anyone out there calculated it? Somehow I doubt it. Anyway what impressed?1. The Sustainable Building Association (AECB), (http://www.aecb.net/) launched their CarbonLite Programme – ‘a crash course in low energy buildings for the design and construction industry’, which usefully draws on experience in Europe and North America, as well as the UK, to provide a scheme that concentrates on simple design principles to achieve genuinely low energy buildings: http://www.carbonlite.org.uk2. On a more domestic level the shower tray heat exchanger that provides heat recovery from the waste heat of a shower to prewarm water from the incoming main and reduce, it claims, by 50-70% the energy used by showering. Apparently installed in 20% of all dutch housing and not yet available directly within the UK it is a simple yet effective way of reducing energy use. How much? About £300 it was claimed, that pays itself back in 3-5 years depending, I guess, on the cleanliness or otherwise of the users. They are looking for a UK distributor so if you know of anyone please get in touch (http://www.hei-tech.nl/)
