Folkestone - Environmental Statement

Flow Analysis Ltd were commissioned to perform part of an Environmental Impact Assessment for a residential and leisure development in Folkestone. Specifically, the task was to conduct a local wind assessment with reference to pedestrian comfort.

A CFD model of the site, the surrounding existing buildings and important terrain features was created.

An up-to-date MET office wind data set was obtained to enable the local wind statistics to be determined. This enabled the analyses to be performed at the appropriate wind speed for 12 wind directions so that the results could be compared with accepted criteria.

The CFD results enabled the local wind flows around site to be determined in detail.

The results showed that the high terrain to the north of the site provides some shelter from winds from a northerly direction. However, the site is completely exposed to the open sea to the south which means that the site is vulnerable to the prevalent wind from between a southerly and westerly direction. 

Without any mitigating measures in place, several parts of the site, most notably to the extreme west and east are predicted to suffer from adverse wind conditions. However, with mitigating measures in place, including additional trees, cycle racks, walls and bunds, the local wind conditions are predicted to be significantly improved.
