SAP Calculations Across the UK

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).

When changes are made to the heating, hot water provision or air conditioning/ventilation services, it is the responsibility of the builder to provide any On Construction EPCs upon completiong of a new home or conversion into fewer or more units.

Any conversions or new dwellings need to have a SAP Calculation and Predicted EPC before any work can begin as outlined in Part L of Building Regulations in the UK in 2006.

What Is A SAP Calculation?

SAP calculations are the Government's Standard Assessment Procedure for Energy Ratings. In order to produce an On Construction EPC (Energy Performance Certificate) or a Predicted Energy Assessment (PEA), a SAP is required, as this is the calculation these certificates are based on.

The higher the SAP rating, the lower the cost will be to run the building. The score represents the cost of energy required by a property over the course of a year with a 100 score meaning there's no energy cost. To calculate the SAP, the assessor uses information relating to lighting, heating, hot water systems, renewable technolgies used and the elements of structure.

How Is A SAP Assessment Undertaken?

Amongst other things, the SAP assessor will determine how good the thermal elements are in the floors and walls as well as 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 which is done off-site but requires plans and drawings of the site in order to be calculated.

The crucial information needed for the SAP software relates to the type of dwelling, floors, walls, the roof, windows, doors, lighting, renewable technologies, 'U' values, hot water and ventilation. With this, we can determine if a building complies with Building Regulations in the UK.
