[Equest-users] ASHRAE 90.1 ERV 50% energy recovery effectiveness - eQUEST inputs?

[Lapierre, Patrick via Equest-users]

It is my interpretation as well and what I always do.

Objet : [Equest-users] ASHRAE 90.1 ERV 50% energy recovery effectiveness - eQUEST inputs?

I'd appreciate some sensible guidance. Please don't dampen my spirits...

Section 6.5.6.1 describes that required energy recovery systems (ERVs) "shall have at least 50% energy recovery effectiveness", meaning "a change in enthalpy of the outdoor air supply equal to 50% of the difference between the outdoor air and return air enthalpies at design conditions".
My reaction is to model this by setting both the sensible and latent effectiveness (ERV-SENSIBLE-EFF and ERV-LATENT-EFF) to 50% (0.50).
Is this correct?

Ye be thanked,
~Bill
