Hi everyone,

I am looking to account for C0 sensors in a basement carpak as part NC building model for LEED. My understanding is that for carparks the baseline model has contionuous extract (something like 5 l/s/m2) but in the proposed case the extract is non continuous and can be modulated by some kind of exhaust profile for the carpark which assumes how many cars are actually being operated in the carpark at any one time. Question is, what do we assume as a profile for this? Is anyone aware of any literature on diversities in carparks which will allow me to account for this more accuratly. I havent found anything in ASHRAE or CIBSE to date. Further to this, does anyone know where i can find information on diversites for occupancy for different space types in order to account for demand control ventilation also? cheers
