SAP 10 Consultancy – multiple dwellings

THE BRIEF

SAP 10 Consultancy

THE PROCESS

  • To achieve compliance, our assessors devised a robust methodology in order to predict the performance of various products under numerous scenarios
  • SAP 10 Beta was used to carry out SAP Calculations on a typical 2-bedroom, 3-bedroom & 4-bedroom dwelling
  • U-Values were set at upcoming Part L notional standards for all dwellings to ensure consistency
  • The calculations provided figures for each of the compliance metrics – Dwelling Emission Rating (DER), Dwelling Fabric Energy Efficiency (DFEE) & the newly introduced Dwelling Primary Energy Rating (DPER)
  • The following scenarios were ran:
  • 1) Gas Central Heating, Hot Water and Solar PV
  • 2) Infrared Room Heaters and Air Source Heat Pump Hot Water Cylinder
  • 3) Infrared Room Heaters, Electric Immersion Hot Water and Solar PV
  • 4) Gas Central Heating and Air Source Heat Pump Hot Water Cylinder
  • 5) Infrared Room Heaters, Air Source Heat Pump Hot Water Cylinder and Solar PV

  • SAP 10 shows a clear shift to electricity becoming more favourable as a fuel source
