SAP Calculations is sometimes referred to as SAP Conversion Calculations, SAP Conversion rating, SAP Conversion Calcs, Part L1B Compliance, SAP Conversion Calc, SAP Conversion Assessment.
What Is A SAP Calculation?
A SAP rating represents the cost of energy required by a property over the course of a year with a score of 100 meaning there's no energy cost. This is calculated from lighting, heating, hot water systems, renewable technolgies used and the elements of structure. The higher the score, the lower the cost of running it.
A SAP calculation, the Government's Standard Assessment Procedure for Energy Ratings, is required to produce an On Construction EPC (Energy Performance Certificate) or a Predicted Energy Assessment (PEA).
How Is A SAP Assessment Undertaken?
A SAP is done off-site but requires plans and drawings of the site in order to be calculated. Amongst other things, the SAP assessor will determine how good the thermal elements are in the floors and walls and how well heat passes through these elements - this is known as a 'U' value. A high 'U' value represents a high amount of heat lost - this is used in the SAP calculation.
The SAP software will determine if a building complies with Building Regulations in Chelmsford using the information provided by the SAP assessment. This crucial information relates to the type of dwelling, floors, walls, the roof, windows, doors, lighting, renewable technologies, 'U' values, hot water and ventilation.
Why Do I Need A SAP Calculation?
If you are selling a home before it has been built, you will need to provide information about energy efficiency in a Predicted Energy Assessment (PEA).
It is the responsibility of the builder to provide any On Construction EPCs when a home is constructed. This will also apply if a building is converted into fewer or more units (material change of use) and changes are made to the heating, hot water provision or air conditioning/ventilation services.
Under Part L of Building Regulations in Chelmsford, since 2006, any new dwellings or conversions need to have a SAP Calculation and Predicted EPC before any work can begin.
