      • Record desired/required space humidity for Annex occupants
    • BioBag research:
      • Denny Voss brought a BioBag he acquired at a trade show. He said it is compostable.After some research, it appears that it must be municipally composted(i.e. ground, turned, heated to 165 degrees in an ideal composting environment).
      • emailed BioBag about temperature needed for decomposition and which composting facilities in Metro- Detroit would accept this product. They responded with composters within 50 miles.
      • Kirsten found research on composting plastics.
  • Food for Thought
  • Session Work
    • Design Altherma Direct to Radiant Floor Heating Experiment for October
