“Think Fabric First” In practice the energy efficiency of a building boils down to a couple of things. How much fuel is required to power its heating and water systems and how well the building manages to retain the heat that is generated.
The better a building performs in these two areas, the less fuel its occupants will use on a daily basis and the lower its emissions will be. As such the fabric of a building is central to its green credentials. Increasingly this is becoming a significant factor in the decision making process for all house builders.
