Energy Assessment of New Build Property - EPC

Current new laws now define the requirements for Energy Assessors for New Build Homes & Dwellings.
SAP - or Standard Assessment Procedure, is the current method used to obtain energy ratings for new build homes or dwellings. The procedure is used to determine heat losses and thermal characteristics of the property by examining the building's plans, the construction materials used in the build and additional factors including space and water
heating. SAP ratings are scored on a scale from 1 to 100 where 1 is the worst and 100 will indicate no heating/hot water cost. It is therefore based on the annual energy costs for space and water heating.

A Target Carbon Dioxide Emission Rate (TER) has to be calculated within the Standard Assessment Procedure (SAP). The Carbon Index is on a scale of 0.0 to 10.0, based on the annual CO2 emissions associated with space and water heating. SAP Ratings are used to demonstrate compliance with building regulations for dwellings - Part L (England and Wales). To produce the required energy rating you will need to appoint a SAP Assessor. The exisiting SAP 2006 is based on a notional dwelling built to the 2002 standards with a target reduction of 20%. The 2010 proposed SAP requires and increase of 25% over the SAP 2006. The actual Dwelling Carbon Dioxide Emission Rate (DER) must now be no worse than the TER. The new SAP 2010 will incorporate all these calculations.
