Dear All,

Specifically for energy models for LEED EAc1, what are typical assumptions
for operation of mechanical room exhaust? The mechanical rooms in a project
I'm dealing with have freeze protection heating only but as per LEED spaces
that are heating or cooling only have to be modeled as both heating and
cooling. For example, one of the mechanical rooms has 8000 CFM of exhaust
and zero Outside Air CFM. How does one model for accurate representation
yet keep the loads from ballooning disproportionately in such a situation?

Thanks,
Ramana Koti.
