2021-Washington State Energy Code.

Does this HVAC tool recognize State of Washington 2021-energy Code ERV requirements for Sensible recover to be not less than 68% or Latinate recover at not less than 60% to pass Washington Energy Code??


Does this tool allow Air-Heat-Pump at 16-SEER  to make-up for ERV less than State of Washington Code requires.  Such that ERV at 60% sensible cooling and 60% sensible heating still passes when requrie is lnot to be less lthan 68%.  Please explain this tool. (HVAC-TSPR) tool.
