You can create an exhaust air flow schedule and assign it to the
applicable zone under the outside air/exhaust tab.  The schedule would
be 1 for occupied hours and .5 for unoccupied.

Subject: [Equest-users] 90.1-2007; Section G3.1.1 exception d;Laboratory
Exhaust

 

Dear eQuest Experts -

 

I am working on a model for a laboratory building where the laboratory
exhaust exceeds 5,000 cfm (combined, not for a single space). 

 

ASHRAE 90.1-2007, Section G3.1.1, exception d, states that "for
laboratory spaces with a minimum of 5,000 cfm exhaust, use system type 5
or 7 that reduce the exhaust and makeup air volume to 50% of design
values, during unoccupied periods." This is a requirement for the
Baseline case. 

 

I am using system type 5 but am not too sure how to model this
requirement for flow rates. Does anyone have an insight to this or know
of any specific instructions for meeting this requirement?

 

As always, thank you for being such a helpful and knowledgeable group.

 

Regards,
