Labs Sessions - 1st Quarter 2018


Labs Session - Jan 5, 2018

  • Labs Updates
    • Catching Up
    • 2018 LABS Topics
      • 1) Finish Up Phase 2 Rebalance and Phase 3 Remaining Issues on Ventilation
      • 2) GG PV System Verification
        • Review new PV system design & specs - original GG PV System Design
        • ENPHASE Monitoring
        • Verification plan - Put data logger on PV produced vs feed to building to compare amps used
      • 3) Re-Commission the HVAC DDC Controls (after Niagara/JACE upgrades)
    • Today's Project: Ventilation Update & Cold Weather Review
  • Ventilation Update
    • Review progress & results
    • Summarize 12/15/17 readings/results
    • Set date to re-read all at once - 1/12/2018
    • Determine if BF needs to be set lower to match ERV?
    • Determine if SF & EF on ERV are okay as is or need to adjust speed to get in balance?
    • Plan for Cave Day
  • GG Cold Weather Review
    • Check systems; capture screenshots
    • Review system cold weather performance; collect trends for past 2 weeks
    • Thermal image doors/windows/floor/tank town walls/etc.
    • Review observations
      • Doors and windows still look very good, even high traffic doors.
      • Exterior door in greenhouse is only spot found that is below the space dewpoint (door wood inset/threshold in 20's; dewpoint 36F).
      • Garage door insulation/seal still excellent.
      • Observed V-6 (three-way mixing valve on floor heating) appeared to be hunting slightly. Joe indicated this is normal for the valve.
    • Consider any additional investigation or recommendations - none
  • What's Next
    • Cave Day - Continue Re-Do of TAB measurements
    • Next Month - Wrap up Ventilation

Labs Session - April 6, 2018

  • Trash Audit Design
    • Check current compliance levels
    • Analyze current waste stream content compared to what it was
    • Issue #1 - Lots of carry out cartons now - CONFIRMED STILL AN ISSUE
    • Issue #2 - Food left in fridge on Friday - CONFIRMED STILL AN ISSUE
    • First audit was 11/4/2011
    • After Action: Talk to Recycle Here to solicit feedback on what we could do better or if anything new in the world of recycling
    • After Action: Drill down to hear what we do right/wrong once it gets to the sorting process or its final destination - update us on what helps and what doesn't - what ruins a stream or makes it unusable
  • Conclusions - Suggestions
    • Businesses to address findings further
    • Labs interested in community aspects of findings
  • What's Next
    • Cave Day
    • Next Month
