SAP Calculations is sometimes referred to as SAP Conversion rating, SAP Conversion Calcs, Part L1B Compliance, SAP Conversion Calculations, SAP Conversion Calc, SAP Conversion Assessment.

Why Do I Need A SAP Calculation?

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.

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).

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 Wiltshire in 2006.

What Is A SAP Calculation?

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).

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.

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 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 Wiltshire.
