Sustainability is one of WINC’s key guiding principles.

Here’s what we said in our guiding document (excerpts):

Characteristics of the community:

We want our cohousing community to …

  • be adaptable, resilient and sustainable

For our natural environment we want…

  • shared beautiful spaces, vegetable gardens and landscaping as well as private gardens
  • green spaces/corridors connected to surrounding bush/gardens
  • to be constantly improving the wellbeing of the natural environment

For our designed environment we want our homes and common facilities to…

  • aspire to the Living Building Challenge environmental sustainability international standard

Inspired by examples of cohousing communities from around the world, particularly the work of Charles Durrett and Kathryn McCamant, the WINC cohousing development aims to be environmentally sustainable and accessible, while also designed to encourage resident interaction

As examples, our design brief states:

0.2. Performance Summary/Sustainability

  • Average 8 star Accurate/FirstRate for the Commonhouse and all dwellings with no one dwelling rating less than 7.5 stars.
  • Minimum Five Star Green Star Rating
  • Strive to meet Passive House performance criteria with regard to insulation, air leakage, solar heat gain, thermal bridging and heat recovery ventilation (such as Lunos ductless energy recovery ventilation)
  • High quality long-life adaptable building

0.3. General Features Summary

  • Strong Environmental Sustainability Design features including (but not limited to) photovoltaic panels, solar hot water and heat pump hydronic heating or reverse cycle heating/cooling
  • All energy needs supplied by electricity, with photovoltaic panels on a substantial area of the most suitable roofs. Aim for at least 105% of energy needs supplied from PV’s
  • Consider no individual electricity meters for each dwelling – one meter for the whole development.
  • No mains gas connection
  • Rainwater tanks, raingarden, greywater recycling system for garden use
  • All living areas to:
    • face true north (preferred) or up to thirty degrees east of true north or 15 degrees west of true north.
    • have full height glazing to the north (minimum double glazing)
    • require minimal active heating or cooling and utilize thermal mass if possible
    • maximise any view or outlook
