Air quality assessments
For developments close to residential areas, Environmental Impact Assessments often need to consider the impact on the local air quality. However, in built environments traditional pollutant dispersion codes such as ADMS (Atmospheric Dispersion Modelling System) are not applicable. Frazer-Nash has a strong track record of supporting Air Quality Assessments in the built environment through the use of Computational Fluid Dynamics simulations, which are ideally suited to these flows.
- We combine high fidelity Computational Fluid Dynamics simulations with local wind and emissions data to determine the pollutant concentrations
- Local planning authorities have accepted our approach, where more traditional air quality assessments have been unacceptable
- We have assessed the dispersion of traffic emissions, as well as power plants and other local emitters. The dispersion of dust from construction sites can also be assessed.
