Wind is nature's ventilator. Regulating how much wind a person is exposed to has significant impact on thermal comfort. Let's see how to do it!

Fig 1: Sketch including a funneling system guiding wind from above buildings into the street level
In more longterm implementations the wind could be funneled and directed to the ground. This might need a constant need for cooling effects which is not given in the Nordics. However, this concept could be adapted on a smaller scale for temporary installations, for example with wind sails guiding air flow into the street.
Fig 2: Principle drawing of an "urban shelterbelt"
Especially in windy climates and sites wind shelter is an important factor for thermal comfort most of the year. In an urban setting a shelterbelt with several rows of trees and hedges is not a practical solution. However permeable windscreen between trunks of trees can still create evvective windshelters for windswept areas. Such a solution has the additional benefit of flexbility, whereby windscreens can be removed in the hot season to allow for ventilation.Â
