Open Sky Co-op – Green Shops Profile (as of March 2022)        

Energy Section


An energy audit was done on the main building about 10 years ago, soon after the property was purchased. The building is divided in two major sections – the residential/office area and the program area.  The residential/office area was itself constructed in various stages since the the original home was built over 200 years old.

The program area was built in 2015. It was constructed using the existing garage/machine shed, thereby, reducing construction waste and maintaining an historical feature of the building.

The residential/office area is heated by a geothermal system that that was in-place when the building was purchased.  Supplemental heat is supplied with a wood stove. Two mini splits, backed up with electric baseboard heaters, heat the program areas.


  • Blown in insulation in the ceiling of the program area
  • Closed cell polyurethane foam was sprayed on the exterior walls and rim joists in the in the basement in 2017
  • About 75% of the original windows in the house have been replaced with 2-ply thermal pane Low-E Argon filled windows. This has been done over several years.

Energy efficiency of lighting and electrical appliances:

  • Use mostly LED lights throughout the building.Some remaining CF bulbs and incandescent bulbs.
  • The kitchen appliances in the residence/office and program areas are energy efficient, for example, there are 3 ranges, 2 refrigerator, dishwasher, commercial sterilizer and upright freezer are Energy Star certified. 1 chest freezer is older and probably not Energy Star Certified.
