SAP Calculations
The indications of energy performance are energy consumption per unit floor area, an energy cost rating ( the SAP Rating), an environmental impact rating based on CO2 emissions and a Dwelling CO2 Emission Rate (DER).
The SAP rating reflects on the dwelling’s energy costs associated with space heating, water heating, ventilation and lighting minus the cost savings from energy generation technologies. The SAP report is expressed on a scale of 1 to 100. Please visit for more about SAP Calculations
