  • baseline economizer changes implemented

    • CA limits updated,
    • default type changed to fixed dry bulb,
    • economizer does get updated when HVAC updated
  • background details are described in section 3.1 and 3.2 in this measure doc

  • mostly @asparke2 's work but I'm running 10k ComStock run now to see the impact of this change but putting up PR to make it visible ahead of time.

  • I did some impact assessment before showing how significant control type change will be (i.e., impact is small) as shown below:

Move the economizer code to AirLoopHVAC.rb and made the economizer type default ComStock specific for 90.1-2016 and 90.1-2019.
