The following changes to iSBEM came into force in England only on 15th June 2022:
Carbon Emission Factors
Carbon emission factor is a coefficient which converts activity data into Greenhouse gas emissions. A significant change to the carbon emission factor for electricity has been implemented within the updated version. This will see electrically heated buildings obtain improved EPC ratings.
The graph shows from 2005 SAP for grid supplied electricity had risen significantly but for the new version of SAP 10.2 this has reduced to 0.139 kgCO2/kWh. This is due to the decarbonisation of the electric grid over the last 10 years to fit with the governments approach to incentivising electric forms of HVAC.
