On this project we used EARTHWOOL insulation batts R4.0 for ceiling, R2.5 for the internal walls and Silversark for the external walls. We minimised holes in the ceiling (yes, avoiding downlights), ensured all external doors and windows were draft proofed. The building’s thermal integrity was thereby protected. You’ll be surprised how much it contributes to a comfortable home.
Most of us know better than to wear black on a hot day, but when it comes to the roofs on our houses, temperature often takes a back seat to aesthetics. Dark roofs mean higher air conditioning bills, and higher carbon dioxide emissions as a result. With a LIGHT COLOURED ROOF you will save money and help protect the planet. You can actually reduce energy use by about 20% in hot, sunny weather.
This house has got wet areas placed together. This not only saves on pipe runs, but it is much more efficient for hot water which can get to the tap at the right temperature faster, reducing waste. We installed a 2000L rain water tank, suitable for the laundry and toilet, which will save water and money. Given that the price of water is tipped to increase up to 300% in the near future, it is a great way to get a head start on keeping water costs under control.
