- Natural Ventilation Guidelines - NV Season - criteria for when to even check to open windows?
- If the forecast high for the day is 70 deg F or greater and the current outside air temperature is 60 deg F or greater, then the NV Daily Worksheet should be used to determine if it is a NV day or not.
- Federal Tax Credit Mismatches with Sustainability
- Building Envelope credit will be included in tax return for 2012.
- Tom needs amount of tax credit and the basic calculation justifying it today.
- After today, plan to document Bldg Env portion of credit per IRS requirements.
- For other portions of credit not pursued, will briefly describe issues encountered during our review related to sustainability.

- Resources Needed: trend log capabilities
- Solar Thermal Panels Optimization
- Check water flow rate (10 gpm per design, manufacturer recommends 1 gpm, is that per panel? We have 10 panels, so is that 10 gpm design based on that?)
- Experiment if flow rate changes when P-2 is on vs. off
- Verify if 10 gpm is optimal flow through panels
- Radiant Floor heated directly from Altherma Experiment (October)
- Update flow system diagram with measured flows for each zone/pump; impact of taking Annex off loop
- Re-calibrate T-6, T-7, and manifold temperature gauges
- Thermal image floor for leaks or inactive sections during heating test
- Extrapolate results to 0-degree F outside day
- Determine impact of 3-way mixing valve being limited on temperatures and operation
- Earth Room Fan / Earth Tube Airflow Setting
- Trend amps on Earth Room exhaust fan
- Set Earth Room Fan speed so average velocity through most Earth Tubes is 85 CFM
- Measure temps / amps to verify optimal integration (optimal heat exchange with Earth Tubes, efficiency of Altherma vs. fan energy)
- Verify optimal setpoints to turn Earth Room Fan on and off for heating and cooling modes
- Annex Heating
- Space temp/RH requirements for occupants
- Passive enhancements - flooring/mats, indoor insulated window shutters when unoccupied
- If necessary, space heating - zoning, heat source, control - Dragon Breath UH

- Schedule trend log training?? - Joe
- Annex Passive Heat Retention Enhancements
- Record desired/required space temperature for Annex occupants
- 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
- Schedule discussion in early October to discuss heating/cooling costs for first year of operation (Tom has cost data and heating degree days)
- Hands-On Activity
- Cut up a BioBag and placed in our compost pile in the backyard to see decomposition rate.
- Get make/model number of GG fridge (cubic feet) for comparison (FCM7SU GE 7.0 cu. ft.)
- Solar Thermal Panel Performance Flow Measurement (may be conducted outside of official lab time)
