<p class="MsoNormal"><span lang="EN-US">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

<p class="MsoNormal"><span lang="EN-US">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).<o:p></o:p></span></p>
