I have a typical situation for DOAS system that serves fresh
air (100% OA) to corridor spaces in multifamily building. The
DOAS unit is equiped with heat recovery wheel, and uses the
exhaust air from apartments, i.e. exhaust from bathroom and
kitchen rather than return air from corridor itself. How would
i model the system that uses recovered heat from one system to
another in the eQUEST.<br>
<br>
Thanks in advance for your help.<br>

having the typical issues with getting an

managed to show a savings in cooling energy, but
I’m getting no heating

actually asking for cold OA
