In an effort to relieve traffic pressure and congestion in the downtown area of Cairo city, an underground multi-storey car park is being built at Tahreer square and it is one of many other underground multi - storey car parks that Cairo governorate is willing to construct. The Egyptian code of garages recommends that, for an underground car park, the CO concentration shouldn{u2019}t exceed 50 ppm in the normal operating conditions and 100 ppm in the extreme peak conditions.This study investigates the performance of the ventilation system of the bus parking area in that project, the analysis was made to investigate the impact of changing the number of buses running and the speed of the ventilation system fans on the distribution of carbon monoxide distribution, air velocities and temperatures inside the bus parking area
