The energy performance of a house will depend on its location, siting, its age and the materials used in its construction. New houses will usually be more efficient than older houses, due to changes in regulations, building and design practice.
Below are some specific measures to consider for standard housing types;
Weatherboard houses are lightweight constructions, typically built with timber framed walls, timber framed floors on stumps, timber windows and roof tiles. Most weatherboard houses are likely to have uninsulated walls.
These houses are typically built with double brick walls, timber windows, and timber framed floors on stumps. Double brick homes have a lot of character – they also have lots of gaps where air can escape, so it’s important to consider draught proofing when renovating your double brick home.
These houses are typically built with brick veneer walls, metal-framed windows and tiled roof, timber floors. Double fronted brick veneer homes are likely to have no insulation in the walls or floors and only a small amount in the ceiling.
These houses are typically built with brick veneer walls, a concrete slab on the ground, aluminium windows and a metal roof. Any home that was built before 1990 is likely to have no insulation in the walls and very little in the ceiling.
