Wind Environment Studies
Case Study Example
A side-stream wind effect was found to be impacting a proposed outdoor dining area. A treatments solution to mitigate this adverse effect included the addition of a free standing canopy at the corner of the undercroft area. This was able to deflect the downwashed side-streams, while the introduction of street tree planting provided protection from incident ground level winds affecting the area.
Project managers and architects now acknowledge the importance of a safe and comfortable wind environment in the vicinity of new buildings. Favourable wind environment in areas that involve commercial activities offer economic benefits that developers are now beginning to realise. The best way of predicting and alleviating wind problems around urban structures is via wind tunnel testing.
Recommended wind acceptance criteria is used to process and compare wind tunnel data. These criteria focus specifically on urban structures where commercial activities occur such as pedestrian movements, window shopping, sitting in courtyards/terraces, or outdoor restaurants.cafes.
When unacceptable wind conditions are found, remedial measures are recommended and the proposed solutions are incorporated into the model which are then tested in the wind tunnel to obtain a definitive result. Some treatment options include:
- Strategic planting of trees/shrubs
- Strategic placement of awnings/canopies
- Erection of screens/baffles
- Efficient design of airlocks
- Adjustment to the building form
- Combination of the above
You don’t have to worry about the design intent of the architect being compromised as Windtech have a policy of providing innovative solutions to make sure that this doesn’t happen.
