Project Description

This single family, detached split level residential home is situated on a corner lot along a bicycle route in the heart of Central Vancouver’s Mount Pleasant neighbourhood. Both the home owner and the builder are committed to building a house that is as sustainable as possible and we are in the process of targeting Passive House certification. Some of the green initiatives we have constructed so far include:

  • Construction waste diversion strategies
  • ICF basement walls = R-42
  • 15” thick exterior walls = R-47
  • Roof assembly = R-57
  • Dow Corning aerogel insulation blankets at R-9.6 per inch to reduce thermal bridging
  • SIGA building envelope system
  • Gaulhofer triple pane high performance windows & doors
  • Zehnder ComfoAir 550 Heat Recovery Ventilator
  • Post HRV make up air boost heater with electric coil
  • Sanden CO2 eco friendly hot water tank
  • Power-Pipe drain water heat recovery exchanger
  • Wolf magnetic induction electric cooktop
  • Electric heat pump ventless condensing clothes dryer
  • Solar tubes for rooftop solar panel futureproofing
  • LED lighting
  • Green roofs
