[BLDG-SIM] parking garage ventilation control

[Michael Haughey]

Hi Aleka,
 
There could be other automatic means acceptable to the local authority
having jurisdiction.  A timer might be one example (off at night, on during
the day).   A good place to start is to ask the code official.  Also check
the code, such as the IMC 2003 if that is what is adopted for the project.
 
Cheers,

Subject: [BLDG-SIM] parking garage ventilation control


Are parking garage ventilation fans required to have some kind of control
that prevents them from running continuously (such as CO sensors)?  I'm
trying to determine whether or not there's an argument for claiming savings
for CO sensors under Appendix G.  My interpretation of section 6.4.3.3.5 in
90.1: "....shall have automatic controls.....capable of shutting off fans
when not required," is that such a control system is required by code.
Also, this seems like standard practice.  Anyone have any insight as to
whether this interpretation is accurate? 

Thanks,
Aleka
