Abstract

Wind is a factor that can open new exploration areas for funtional and morphological purposes, in the architectural design discipline. In these areas is possible to develop new design strategies to improve the levels of enviromental comfort. This article presents the assessment and use of three independent studies on mitigation and control strategies for wind comfort, collecting and combining some design rules that they propose, which are based on their aerodynamic features. These are the studies of the aerodynamic “slot” porous screens and fuselages. Thus, a combined and strategic use in three technical-architectural elements is proposed as a rule to design a protection canopy for areas of public space with a high level of discomfort caused by the wind and with lack of other mitigating measures. The use of these aerodynamic principles allows to design a semi-open structure, making it less cumbersome, less invasive and lighter in for pedestrian areas. The term “wind thresholds” is coined to identify the effect of a deflecting and protective gust of wind in the form of a dome or bubble, which is generated by the combination of these elements. The effectiveness of this strategy for wind control is tested with computational fluid dynamics models, seeking to verify that there is an effective mitigation and deflection of the wind that increases the protection zone.
