Modelers,

We have relief/exhaust louvers located very close to the intake louvers in an existing mechanical space, and are trying to show the client how this kills their energy consumption. This lowers energy saved from the economizer during winter months, and also makes the unit work even harder in the summer.

Is there a way to raise the OA +20 deg over ambient, for the whole year, and for specific AHUs? I think this will be a decent estimate on the increased energy consumption from this scenario. Or maybe someone has modeled this a different way??

Any help is greatly appreciated. Thanks!
