| summary |
This paper discusses wind comfort improvement strategies as a crucial microclimatic
issue in urban planning. The investigation used pergolas as a wind catcher/breaker
element to improve wind comfort at the pedestrian level in Tallinn, Estonia, during
extraordinarily windy and cold times of the year. We analyzed the impact of buildings and
other surrounding elements on wind flow to design pergolas as windbreakers. Case
studies include three urban areas. The wind flow has been simulated using Computational
Fluid Dynamics (CFD) on the micro-climate scale using ENVI-met. The CFD analysis
allowed us to understand urban wind flow phenomena and apply solutions to mitigate
distress and guarantee more comfort. According to the CFD results, the urban zones
show a high rate of wind speed under different meteorological conditions and,
consequently, extreme wind discomfort. The analysis results of 48 scenarios based on
different meteorological cases were used to select the most performative retrofit solution
and provided insight into windbreak pergolas’ size, layout, and location to provide
comfort. Thus, improved geometrical models of case studies were simulated and analyzed.
The results showed that the designed pergolas offer high wind comfort at the pedestrian
level, especially in open urban areas, and could assist municipalities, city planners, and
urban designers in creating more comfortable and sustainable urban environments. |
