City Sends Spy Planes Out To Determine If Your Home Is Wasting Energy

from the only-trying-to-help dept

It's no secret that not everyone realizes how wasteful they are of energy resources. However, apparently one city in the UK went to rather extreme measures to make that point clear to residents in the city. It hired a spy plane to fly over the city and take heat loss photos across the entire city. The photos were then matched to a city map, displaying which houses were leaking the most heat at the time the spy plane passed over. Eventually, the entire map was put online so everyone could see which buildings were wasting the most energy. What's unclear is whether or not these heat maps convinced anyone to actually do anything (or if it just freaked people out).

    Re:

    Think about that for a moment. If a house is using 25 times the energy as the next one along, hes paying 25 times the electricity bill!

    Ironicly the ritch don't pay that sort of bill, because they can afford to fit good quality insulation and double-glazing.

    But you can't just phone up a power station and ask how much power someone is using, because that will violate provider/consumer confidentiality. Its not representative either, as naturally a larger or older house will cost more to heat.

    But all this isn't to say the technology doesn't work; it does. A propper thermographer will consider the outside temperature and the inside temperature (clearly you can't do this if the two are the same), along with the thickness and surface area of the walls. He'll then consider the energy going in to heat the house, the proportion its loosing and tell you where you can invest to reduce this.

    If this is intended as a publicity piece, fine. Raising awareness of these issues is important. The danger is that people consider this credible, and run out to spend money on new double glazing they don't need.
