Section 6 Technical Handbook- Domestic
This technical document covers the conservation of energy within dwellings and buildings consisting of dwellings.
As with other parts of the UK, Standard Assessment Procedure (SAP) is used for measuring the energy performance of new dwellings. SAP can determine the energy performance and CO2 emissions of individual dwellings, which is a key concern for the government and their carbon emission targets.
New Dwellings, Section 6
SAP is used to calculate a Target Emission Rate (TER) which is determined based on a 'notional dwelling' of the same shape and size. A new build property must achieve a Dwelling Emission Rate (DER) which is equal to or lower than the TER in order to comply with Section 6 at a design stage and also after the property is constructed.
Section 6 also provides a classification for dwellings in terms of their sustainability from Bronze all the way to Platinum.
Existing Dwellings, Section 6
Alterations to a building or extensions to a dwelling could result in SAP Calculations for Building Standards compliance.
Change of Use: Changes in the occupation or use of the building (commonly known as conversions) may require SAP Calculations in order to demonstrate the energy performance of the property. An example of this could be, a hotel converting to a dwelling or a division of a house into multiple flats.
Building Extension: Extensions with glazing amounting to 25% or more, of the total extension floor area, may require SAP Calculations to demonstrate compliance.
