1.4.12 Vegetative Wind Breaks
Control dust and wind by planting dense trees and plant material to protect from undesirable, harsh weather conditions, i.e. cold winter winds from a prevailing wind direction or windtunnel-effect in outdoor plazas.
Earthforms, berms, trees and shrubs.
Early wind analysis and coordination with landscape and mechanical engineers.
Wind breaks can significantly reduce winter heating costs and summer cooling costs.
Strategic placement of vegetative wind breaks can enhance passive cooling (summer) or reduce energy loss with respect to reduced exposure to cold winds (winter). They further mitigate wind erosion, sand movement from sand dunes, deposition.
For optimal windbreak design in terms of its porosity, distribution with height and the number of rows needed, wind-tunnel testing might be valuable.
