All new domestic buildings require a SAP calculation (Standard Assessment Procedure) for building control submission. This is carried out using accredited software by a trained  competent person.  For developers we can also provide you with a Predictive Energy Assessment which can be used as marketing information. This will provide details of the dwelling designed energy performance. The PEA should be replaced with the EPC upon construction completion and should the constructed details instead of the design details.

There are many factors taken into consideration in the calculation including:

·        Building fabric (U values)

·        Construction detailing (air tightness)

·        Equipment selection (Boilers, lighting air conditioning)

·        Building  orientation and solar gains.

3-Saints Staff are registered competent persons and can carry out the SAP calculation and advise on how to improve the dwellings performance in a cost effective manner.   With over twenty years experience in the design and construction of properties, we have the experience and knowledge to advise you on the most cost effective method of compliance.
