  • 25 tonnes CO2 emission saved from solar PV (June 2015 to August 2018)

Approaches Used

  • 35 x 9.45 kWp PV panels producing 36.35 MWh from 2015 to 2018.
  • Ground source heat pump (5kw) with collector pipework installed in standard concrete piles
  • Cement only used in foundations and brickwork below damp-proof course
  • Structurally insulated panels (SIPS) used for timber frame
  • Materials reused or with recycled content – glass fibre insulation, plasterboard, roof slates
  • Timber salvaged from demolition for garage timber frame, granite setts, recycled glass kitchen worktops
  • Pre-finished double-glazed timber windows
  • Triple glazed bi-fold doors and rooflights
  • No gas use on-site
  • Mechanical ventilation and heat recovery system
  • Timber finishes to cladding, staircase, flooring and doors
  • Green roof and sustainable urban drainage system (SUDS) used, including permeable paving
