The latest news and case studies from Sadler Energy

The Governments Standard Assessment Procedure (SAP) for assessing the energy performance of dwellings. The indicators of energy performance are energy consumption per unit floor area, an energy costing rating (the SAP Rating), and Environmental Impact rating based on CO2 emissions (The EI rating) and a Dwelling CO2 Emission rate (DER).

The SAP rating is based on the energy costs associated with space heating water heating, ventilation and lighting, less costs savings from energy generating technology. It is adjusted for floor area so that it is essentially independent of dwelling size.

The SAP rating is expressed on a scale of 1 to 100, the higher the number the lower the running costs, this can then be but into a band from A-G. (A being the lowest running costs, while G represents the highest costs).

The SAP Rating scale is assigned to a rating band according to the following table.

1 to 20G
21 to 38F
39 to 54E
55 to 68D
69 to 80C
81 to 91B
92 or moreA
