>> It's raining on this old house, but not really. This is a replica of a Victorian-era house, which is itself housed inside a climate controlled laboratory in England. All so that researchers at the University of Salford can figure out how to make millions of old homes like this.
More energy efficient.>> So we can put sun on the building, we can put rain on the building, wind on the building, and we can also reduce the temperature down to minus 12 and up to plus 30 degrees C. The purpose of this facility is to look at retrofitting measures on buildings, so things you can add onto a building to make it more efficient.
Like I said so external wall isolation new windows cetera cetera. So because we have this IG housing stock in UK they very difficult to work with and the paradox is that the older the building we find the greater technology needed to improve it and also greater the risk Things like damped condensation, etcetera.
>> It's also automated to simulate a family living there. Open doors, opening the fridge, flushing the tiolet and such. A lot of renovation such as insulation and new windows are of course ver costly though. The university says a full retro fit on house like this could run up to almost $20,000.
But there are simple things they say that can also help. A smart energy meter for one, which is sometime installed for free by utility companies And they found that just closing these curtains saves 40% of the heat that would normally pass through the windows.
