One of the most energy efficient single family home retrofits ever attempted in Canada is now under way. The project will be carbon neutral and feature a 3.5 kw PV installation, a 10,000 litre cistern for rainwater capture and reuse, and will use healthy and environmentally friendly building materials. Construction is beginning now and occupancy is slated for December 2010. The project is being initiated and led by BuildGreen Solutions, the consulting and development management arm of Windmill Developments (best known for the groundbreaking Dockside Green development).
