What's new in SAP 2012? There have been many changes in SAP 2012, some of which are to make the calculation more accurate, and some to make the system more flexible, enabling a variety of new and existing technologies to be included.
  1. climatic data has been extended to allow calculation to use regional weather data based on region or postcode.
  2. an allowance for height above sea level is incorporated in the external temperature data.
  3. carbon emission factors, fuel prices and primary energy factors have been extensively revised.
  4. options for heat losses for primary pipework have been extended
In England and Wales the SAP is consistent with the 2013 Building Regulations which have introduced new indicators for compliance, namely the calculations of Dwelling Fabric Energy Efficiency and Target Fabric Efficiency. For Scotland the calculations are consistent with Technical Handbook 2015, Domestic, Section 6, with the TER parameters depending on the fuel used for main heating.
