The way we transport ourselves ischanging; we’re growing our own food more and recycling as many drinks cans andmilk bottles as possible. We always think of beams as beingwooden, but the Steel Recycling Institute tells us that builders prefer to usecustom-made steel beams and panels in their newest projects. Steel is muchsafer in high winds and earthquakes, and a 2,000sq ft house needs at least 40trees as its skeleton. If you use recycled steel beams, you’re going to use theequivalent of six scrapped cars! Steel isn’t the only metalleading the eco-revolution. Aluminium is also very recyclable and very light,and it’s finding its way into lots of buildings now. You could have analuminium roof on top of a house, an aluminium busbar in the electric wiring ofan apartment block, aluminium wall cladding… most aluminium you see in use hasalready been recycled, so it’s got serious eco-cred. Concrete has gone in and out offashion over the centuries, but it’s currently in vogue thanks to itsinsulation and energy-saving properties. Some builders have started to use”cast-in-place” concrete walls that are cast in between two layers ofinsulation material. These insulating layers are then left where they are tocarry on slowing down heat transfer. This is a useful technique for makingbuilding blocks. Low E windows are coming our way,too. The E is for emissivity. These windows have a clear metallic oxide coatingwhich helps to keep heat inside when it’s cold and outside when it’s hot! Thistype of glass tends to be used in single-pane storm windows, and these panescost around 15 per cent more than regular glass, but when you think of the savingsto be made on heating and air conditioning (up to 20 per cent each year),they’re worth the premium.
