What's new in SAP 2009? There have been many changes in SAP 2009, 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.
In England and Wales the TER is calculated assuming a 25% reduction in carbon emissions compared to SAP 2005. The calculation of the TER for Scotland is more complicated, using one of five different packages of parameters, Gas, LPG, Oil, Electricity or Biomass depending on the main heating fuel. If there are two heating systems it uses the fuel which has the highest Carbon Factor, and if there is community heating with multiple heat sources and different fuels it does the TER calculation up to five times weighting the results according to the heating fraction of each heating source. Sapper version 9 does this automatically with no need to use the BRE spreadsheet.
