The Energy Performance Certificate is similar to the certificates found on many domestic appliances. A Certificate for a building gives the building an asset rating based on its energy efficiency. Data is collected by the domestic energy assessor such as floor area, construction, insulation, heating and lighting and input into a management software programme. Certain assumptions are made on how the home is used by the occupiers. This is referred to as `Standard Occupancy`.The EPC produced will give the building a rating from A to G. An A rating shows it`s very efficient, meaning lower fuel bills, while G is inefficient, meaning higher fuel bills. The Certificate will also show the building`s environmental impact by indicating its carbon-dioxide emissions in exactly the same fashion i.e. An A meaning low emissions and G meaning higher emissions.
The EPC will also show recommendations as to how the property could be made more energy and cost efficient. The Potential ratings included within the Energy Survey indicate the effects of each recommendation.
