Planning requirements often mean extensive car parks to proposed offices, residential And retail developments. The ventilation of these car parks can present a significant cost to the developer in terms of capital expenditure for plant, energy consumption and maintenance, as well as the implications for the programme if extensive ductwork and plant has to be installed.

The use of Computational Fluid Dynamics (CFD) is most effectively used at early design Stage: ‘prevention is better than cure’, but can be used as a tool for solving existing Problems. The specific objectives of a project can vary considerably. The key objectives of the simulations are normally to ensure that the distribution and concentration of carbon monoxide (CO), is in accordance with Building Regulations.
