Notional Dwelling Fabric Energy Efficiency

SAP Calculations
Barn Conversion SAP in Gloucestershire

The brief

The process

  • Fabric efficiency targets were met through low u-values of all external walls, floors and roofs

  • Low glazing U-values also helped to achieve fabric efficiency targets

  • Emissions targets were met by installing an air source heat pump rather than a traditional gas boiler

The results

  • SAP RESULTS

Notional Dwelling Emission Rate (DER)

Notional Dwelling Fabric Energy Efficiency (DFEE)

  • Compliant

  • The proposed dwelling is more efficient than the notional dwelling therefore compliant with the Part L Building Regulations
