energy performance improvements to 3 bed semi
The existing house
The house is an 970ft², 2 storey semi detached dwelling with 3 bedrooms and was built in 1993. It had the original oil fired central heating, insulation in the attic, polystyrene insulation in the cavity walls and double glazed timber windows.
The home owner wanted a warmer home with lower bills.
£400 of works saves £260 a year
Works to improve the lights, air tightness, insulation and hot water cylinder totalled £400. The home owner done some of the works himself. This reduced the annual energy bill from £2,305 a year to under £2,045 saving a £260 a year.
dwelling performance summary
We invested around £400 to improve dwelling performance and save £260 a year giving a payback of around 1.5 years.
Replacing Halogen bulbs with LED bulbs also reduced light bulb replacement costs as the LED bulbs should last 6 times longer than the Halogen Bulbs. The LED bulbs should last 20 years.
We also tried different bulb brightnesses and colours for each room so that the new lighting scheme was better than the old one.
The works made the house warmer, reduced draughts and reduced energy bills.
