    How many times outdoor air is reduced or closed in the name of energy efficiency?

    When ERVs first came out (I know they have been around for 25 years at least) I thought they would be on every building. Not from what I have seen. To me the ability to recover the exhausted hot or cold air and recover 80% of that would be a no brainer.
    I was wrong on that one

    So true,
    IMO, all commercial HVAC systems should be measuring CO2 and manipulating OA dampers and/or Erv's to keep the levels in check. I manage several buildings that are set up this way.

    This one is for a ski lodge restaurant. This unit is for the dining room. It uses input from the lighting occupancy sensors, outdoor temp, CO2 as well as the pressure differential created by the kitchen exhaust to keep everything nice and comfortable.
