Welcome to Jersey SAP
BRE SAP Engine
This website provides support for the use of a tool designed to produce energy performance assessments for domestic buildings as required by the Jersey Building
Bye-laws. When provided with details about the dwelling configuration the Calculator will show if the energy performance targets set by the building bye-law have
been met, and it will provide an energy performance certificate giving an estimate of the likely running costs, SAP ratings, etc.
The Jersey SAP tool was created by BRE.
