[Equest-users] CO sensors in parking structures

[Cam Fitzgerald]

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
