Background

- SAP is the Government's Standard Assessment Procedure for Energy Rating of Dwellings

- It provides the following energy performance indicators:

     - Energy consumption per unit floor area

     - Energy cost rating (the SAP rating)

     - Environmental Impact rating (based on CO2 emissions - the EI rating)

     - Dwelling CO2 Emission Rate (DER)

Why do you need it?

     - It is required as part of the Building Regulations - Part L

     - It forms part of the Code for Sustainable Homes

      - It forms part of an Energy Performance Certificate (EPC),

     required when a building is built, sold or rented out

     - Most Planning Authorities have a requirement for a percentage of a

     development's energy to come from renewable or low carbon energy

     sources for planning permission requiring a SAP Assessment to show this

     - It helps to provide information on the energy performance of alternative

     design decisions

     - It is also a way of demonstrating the energy efficiency of a development

     for corporate or marketing purposes.
