Home of the MADD Scientists - "Making A Difference Daily"....we hope!!!

return to Sustainability Labs
go to Labs Sessions - Q4 2011
go to Labs Sessions - Q1 2012
go to Labs Sessions - Q3 2012


Performing scientific study to support sustainable stewardship of our Community and Earth. Seeking the truth of our actions and having fun doing it. 

   GG Labs Sessions are held each Friday after the Community Lunch, 
   starting at 1:30 p.m. and ending around 3:30 p.m., depending on the day's agenda.
   All are welcome to join in!

      • Air Filter Gauges with OCD
      • Updates to cooling controls - Expert/Cochrane
        • Controls updated June 21st
        • June 22nd test of Cooling of Zone 1
        • Floor Temperature at onset: 77.1F
          • Zone Cooling Loop Setpoint set to 65 degrees F
          • Zone Cooling Loop set to 60 degrees to speed up cooling process
            • Water into zone 1 floor loop reached 62.3 degrees F
            • V6 Cmd modulation
            • 76.2F Floor temperature
          • Conclusion - Faster cooling with running air through dehumidificator coil than running through floor.
        • Conversation with Chad about high humidity in his workshop
          • Sensor 2 moved to workshop to monitor humidity: 3:00pm temp = 73.9F (main building = 76.2F - 77F), humidity = 68.6% (Main building = 55.6% - 56.5%)
          • Impact issues:
            • Poor air circulation: need to increase air movement - supply air to be ducted to Chad's area. Return air ductwork location subject to further discussion.
            • Moisture entering through cement block walls and cement floor: - would require a moisture barrier.
    • Labs Experiments
  • Food for Thought
  • Session Work
    • Finalize plan for Measurement of in-ground tank volume/dipstick calibration
