Pollution control

Challenge:

 

Parking structures in cities tend to be either underground or occupy a “land-locked” position within a building; external façade space is usually reserved for occupant areas such as residences, offices or retail. 

 

As such the build-up of exhaust gases within the space could lead to unpleasant odours and in extreme cases over-exposure to harmful gases such as Carbon Monoxide.

 

To prevent this harmful build-up of gases, ventilation of the parking structures is required, however significant energy can be spent in this if adequate control of the system is not provided.

 

Description:

 

Ventilating an enclosed car park at the maximum duty specified by regulation can result in very high whole-life cost for the project and increased machine maintenance requirements.

 

An early approach to solve this issue was to base the system operation on the expected usage of the car park; however this could result in over or under performance of the system if the usage differs from that predicted and if regular monitoring and updates are not conducted on the system.
