[Equest-users] LEED modeling garage

[Nick Caton]

I think Karen's second sentence reads better if you tag "... as a direct load to the meter" to the end =).

To the second query, which dances with the "one system per space" rule of DOE2:  Something I've done in the past is split a space into two spaces thermally connected with an air wall (copy the space, halve the area/volume/internals, adjust & re-assign the interior partitions for the air wall), then assign the unit heater to one and the cooling system to the other.  Carefully review the temperature inputs to ensure the systems aren't fighting each other.
An easier approximation could be to simply include baseboard heating under the system in question.

if the garage is completely open and unconditioned, then don't model the garage space at all.  Simply model the lighting, and any energy used by an exhaust fan for CO and NOx control.

Hello, I just wanted to follow up on this and see if anyone has any information on how to model the garage grilles?

Also one other question - if a space has an AC unit plus and unit heater, how should that be modeled?

Thank you

Hello,

I'm currently working on a model for a LEED project.  The parking garage is heated only with unit heaters and no cooling.  The garage is also ventilated naturally with aluminum grilles.  What is the correct way to model this for a LEED project?  Also, how do I take the grilles into account?  I currently have them in as windows, but I am not sure what do since they are essentially openings in the envelope.

Thank you
