When are SAP Calculations for Conversions required?
A SAP Calculation is mandatory for development projects creating new dwellings through material changes of use or alterations to energy status. Here are some specific scenarios:
-
Conversions transforming existing non-residential buildings into dwellings: This includes projects like barn conversions or office buildings converted into flats.
-
Internal reconfigurations leading to more dwellings: This encompasses situations like converting houses into flats or modifying existing flat layouts to create additional units.
By requiring SAP Calculations in these instances, regulations ensure that new dwellings meet energy efficiency standards and contribute to a more sustainable built environment.
A change in energy status occurs when a space previously not requiring heating or conditioning, like a garage or workshop, is designed to become a heated or cooled living area. This often happens alongside material changes of use, where the space's primary function is transformed into a dwelling.
​
For example, converting a garage into a habitable room would necessitate both a change in energy status (requiring heating/cooling) and a material change of use (becoming a living space). Requiring SAP Calculations in such situations ensures new dwellings, regardless of their previous use, meet energy efficiency standards.

More on SAP CalculationsThey assess a home's annual energy use for heating, hot water, lighting, and ventilation based on standard occupancy and temperature settings. This allows for fair comparisons between different dwellings using an SAP Rating. SAP Calculations also estimate a property's annual CO2 emissions (Dwelling Emission Rate - DER) and its energy efficiency for the building itself (Dwelling Fabric Energy Efficiency - DFEE) and energy use from renewable sources (Dwelling Primary Energy Rating - DPER) - England only. In new builds, these figures must be lower than set limits (Target Emission Rate - TER, Target Fabric Energy Efficiency - TFEE, Dwelling Primary Energy Rating - DPER) to comply with building regulations (Approved Document L: Volume 1). Finally, SAP calculations are used to generate On-Construction Energy Performance Certificates (EPCs) for all new dwellings.

Best Time for SAP CalculationsEarly design stage: Once you have internal layouts and a basic building plan, it's ideal to complete your SAP calculations. Benefits of Early Completion: Easier to make adjustments if needed based on the assessor's recommendations. Fulfills most Building Control Body (BCB) requirements for design stage calculations before construction starts. Final Stage: After construction is complete, the initial SAP assessment is updated to reflect the final building ("As Built"). This final calculation is used to generate your On-Construction Energy Performance Certificate (EPC).
-
What Affects Your SAP Rating?Your home's SAP Rating considers several aspects that influence its energy use and CO2 emissions: Building Features: Location, orientation, wall construction, window efficiency, air leakage (from air tightness test). Building Systems: Heating and hot water system efficiency (including fuel type), ventilation system type. Energy Use: Internal lighting usage, solar heat gain from windows. Renewables: Presence of renewable energy technologies. A higher SAP Rating indicates better energy performance.
-
Who Can Do SAP Calculations?For efficiency and to obtain an On-Construction EPC, a qualified and accredited On-Construction Energy Assessor is best. They're the only ones authorized to issue the final certificate. Our Recommendation: Choose an assessor with experience in all SAP versions and current Building Regulations to avoid costly mistakes during construction.
