All new dwellings must have an assessment of energy efficiency performance, environmental impact and building regulations compliance undertaken at design stage prior to the commencement of works on site.
SAP is the ‘Standard Assessment Procedure’ methodology used to produce a calculation and its resulting outputs are used to demonstrate to a Building Control Body that a building will be constructed in compliance with appropriate regulatory guidance. This calculation is then updated once the house is physically complete, to produce an Energy Performance Certificate (EPC) for the finished dwelling and to show that the completed property complies with the regulatory requirements.
Our accredited assessors can undertake energy calculations on request as part of a charged for service, which can guide the customer through the relevant building regulations requirements and offer advice where initial proposals may fall short of compliance.
In order to undertake calculations, construction drawings including plans, sections and elevations are required, together with proposed specifications for all of the above elements. On completion of a build, those calculations can then be updated with further information, in order to produce EPCs.
