<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">The amount of outdoor air in the baseline determines whether or not the baseline requires heat recovery. The amount of outdoor air in the baseline depends on
the ASHRAE 62.1 outdoor air amounts or the mandated exhaust/make-up air flow – which ever is larger. Given that the space is a car garage, exhaust likely determines the baseline outdoor air amount.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">By way of an example, I am working on a project that has 100% OA systems. They are VAV systems with the minimum flow equal to the 62.1 calculated value ramping
to maximum flow for cooling. The proposed design has ERVs. The baseline outdoor air is equal to the 62.1 calculated values but the total supply flow is such that the percentage of outdoor air is less than 70% so the baseline doesn’t have heat recovery.
