Greg:

The ASHREA Applications Handbook has a chapter on Enclosed Vehicular Facilities that has some good information on parking garages that may help.

Have a nice day!

Hi Nathan,

Could you provide a source for your back-up studies?  I would like to review them, if possible, and see if I can utilize them in my effort.

Thanks,
Greg

That is basically how I got credit with the USGBC for CO controlled parking fans. I provided some back-up studies that showed how rarely fans have to ramp up in a parking garage. When cars arrive, they are running hot and are barely emitting CO, so for an office building parking garage there might not even be much of a morning uptick.

Hi Greg,

When I did it way back, I created a schedule to reflect the reduction. My thinking was along these lines: the baseline schedule would reflect the occupancy schedule, ie the normal coming and going of people in the building; the proposed schedule would have a high % when people arrived, go to a min level for awhile, have another high % at lunch, go to another min lovel for awhile and then another high % when they left. This all depends on what your building type/usage is, of course, and requires sound engineering judgment to do a good job. Document all assumptions, like cars emit CO when they are running not when they are parked, and when the reviewer asks why say "because I said so". Oh sorry, don't say that, just provide your assumptions.

If you need further assistance, let me know.

Good night,

Carol Gardner PE

Hello Everyone,

Is there a way in eQuest to model ventilation fans with CO sensors in parking structures?

Thank you in advance for your help,
Greg
