[Bldg-sim] Appendix G: Cooled space?

[Kevin Kyte]

Did anyone come up with an answer for this?  I have a similar situation.  My
thought would be that it should be considered a cooling system.

My thoughts on this would be that your main system should be sized to
provide the fresh air at your cooling temperature to replace the air
rejected by the exhaust, and you will probably find this is happening unless
your space is negatively pressurized.

I have a mechanical room that is conditioned to 95 in cooling through
exhaust fans and heated to 65 with unit heaters.

 

Do the exhaust fans constitute as a cooling system?  The system would need
to provide a sensible capacity of 5 btu/h*ft2 for the mech room to be
considered to be a cooled space, which I have not yet calculated.

 

The reason I as is that if these exhaust fans are not considered a cooling
system then the baseline cooling system will need to be modeled to complete
an accurate LEED model.

 

Any suggestions?

 

Tim.
