Havencraft: Grid Tie Net Zero Straw Bale Home


Grid Tie Net Zero Straw Bale Home brought to you by Ontario Natural Buildings Coalition

HavenCraft was formed by Sherri Marcotte and Patrick Marcotte, M.A.A.T.O., C.E.T., LEED Green Assoc. in 1999 and was incorporated in 2007. We are based in beautiful Bancroft, Ontario and have the pleasure of working in and around the lakes and woodlands of this great region! Patrick is an Architectural Technologist, a Certified Engineering Technologist, a LEED Green Associate, and is fully registered with the Ministry of Municipal Affairs and Housing as a designer. He is licensed to design residential, commercial and low hazard industrial buildings. He is also a Red Seal Journeyman Carpenter which helps with some of the practical aspects of designing.

We believe in practicing what we preach. Our office (and home) is operated in a highly insulated super energy efficient building.

Here’s a list of some of the concepts we’ve put into practice that has helped us to learn along the way:

  • highly insulated envelope with walls made of straw bales,

  • passive solar design which helps heat in the winter and keeps us cool in the summer,

  • ground source heat pump (geothermal) which heats the water we pump into our in-floor heating system,

  • active solar electric panels (PV) tied to the grid with Ontario’s MicroFIT program. The heat pump and the PV help us to be Net Zero Energy in that we produce as much electricity as we use annually,

  • efficient Rumford-style wood burning fireplace,

  • healthy materials which don’t off-gas chemicals into our breathing space, helping to keep our indoor air quality high,

  • recycled and reclaimed materials such as interior doors, insulating foam, Enviroshake roofing,

  • on-demand domestic water heater,

  • zero chemicals for gardening and landscaping

Learn more about this home at this year’s Green Energy Doors Open event happening all across Ontario a long with Alberta and B.C. This home tour is in collaboration with the Ontario Natural Buildings Coalition and their annual Ontario Natural Buildings Tour.
