SAP / EPC Calculations

a2UK Air Testing works In the same office as UK SAPS, therefore although the business is a separate entity it is all under one roof , so you still receive all the convenience and benefits of the services being through one contact. UK SAPS has completed in excess of 15,000 SAP calculations to date and were first accredited back in 2007. Therefore we have a very detailed knowledge of the regulations and the requirements to get your properties passed.

Water Calculations

The Government updated Part G of the Building Regulations in April 2010. This sets a whole building standard of 125 litres per person per day for domestic buildings. The calculation method requires the use of water consumption figures provided by manufacturers product details.

SAP – Standard Assessment Procedure

SAP is the UK Government’s standard methodology for home energy rating. SAP ratings allow comparisons of energy efficiency to be made, and can show the likely effect of improvements to a dwelling in terms of energy use. The SAP rating is based upon running costs for space- and water-heating and lighting, which are calculated taking account of the shape and fabric of the building, its thermal insulation, the fuel used, and the performance of the heating system

EPC – Energy Performance Certificate

This energy performance certificate (EPC) must be provided whenever a property is constructed, rented out or sold. The EPC shows the energy efficiency rating (relating to running costs) of a dwelling. The rating is shown on an A–G rating scale similar to those used for refrigerators and other electrical appliances.

PEA – Predicted Energy Assessment

Predicted Energy Assessments are for homes that are not yet physically complete before or at the first point of marketing. Normally, when a home is designed, a “target energy rating” based on the design is produced to show a building inspector that the property will meet requirements under Part L of the Building Regulations. The final energy performance of the property must achieve at least this target energy rating to receive its final sign-off from the building inspector

TER – Target Emission Rate

The TER is the minimum energy performance requirement for new buildings and large extensions and is calculated in accordance with Standard Assessment Procedure. The TER provides the target that the proposed building or extension must meet.

DER – Dwelling Emission Rate

To assess compliance with the Building Regulations the TER must be compared to either the DER calculated for the proposed building. Confirmation of the TER and DER is needed at both the design stage (as-design SAP) and at completion (as-built SAP).
