SAP Calculations and EPC's (Energy Performance Certificates) SES have Elmhurst Accredited SAP Assessors who can carry out SAP Calculations for compliance with Part L1A & L1B of the Building Regulations.
We can help you achieve your SAP certification by offering advice, recommendations and action at all stages of the process. Part L of the Buildings Regulations requires that all residential developments must conform to specific target requirements on energy efficiency & CO2 emissions.
SAP is the method of measuring the energy efficiency of new-build residential buildings. It involves the use of a ‘notional’ model to evaluate new-build projects to produce a Target Emissions Rating (TER) in line with Part L of the Building Regulations.
SAP takes into consideration
- Building materials
- Insulation values
- Thermal Bridging
- Ventilation
- Air Tightness
- Heating and lighting
- Renewable energy
technology
EPCs
Once the building is complete the SAP Assessor will confirm constructions used, incorporate the air test result where applicable and produce the As Built SAP Report and Energy Performance Certificate (EPC). This certificate is required for handover to Building Control and also for the rent/sale of the property.
SAP Calculations & EPCs will be required for:
- New builds
- Any existing property being converted into a dwelling (i.e. former office buildings being converted to apartments)
- Extensions to dwellings where the glazing is more than 25% of the floor area being added
