Abstract
In the climate change era, the tendency to utilize computer-aided strategies in architectural design enables the incorporation of the influences of ambient conditions into the design process. Such a design strategy can consequently contribute to creating nature-based, sustainable architectural, and urban solutions. In this paper, it will be shown that the built environment can be designed, already from the first concepts, to affect and consequentially improve the local wind microclimate by addressing the unfavorable wind effects and proposing solutions for transforming them into an advantage. Utilizing the iterative Research Through Design (RTD) approach, the proposed data-driven wind-oriented shape optimization is introduced in a case study located in Stockholm. Three complex architectural shapes, resulting from the wind-oriented design approach, are parametrically designed in Grasshopper for Rhino and subsequently analyzed in a Computational Fluid Dynamics (CFD) plug-in Swift for Grasshopper.
Highlights
The substantial evidence of changing climate [1,2] is a trigger for architects and engineers to reconsider the conventional approach to designing the built environment and instead come up with environment-based, climate-conscious design strategies [3,4,5,6]
Except for the analysis of high-rise buildings and skyscrapers or extreme windsMoreover, the Computational Fluid Dynamics (CFD) simulations are valuable in architectural prone areas [13], little attention has been paid to the wind evaluation of building designs during their design [14], they are still not a part of the standard architectural practice, especially not in the early creation
The designs incorporating the wind can be aimed at different goals, depending on the designs incorporating the wind can be aimed at different goals, depending on what what kind of wind-architecture interaction is beneficial for the specific site: natural ventilation, kind pollutant of wind-architecture interactiondesigns, is beneficial for the specific site:and natural pollutant dispersion, aerodynamic pedestrian wind comfort, wind ventilation, energy harvesting dispersion, designs, pedestrian wind comfort, and wind energy harvesting (Figure 2)
Summary
The substantial evidence of changing climate [1,2] is a trigger for architects and engineers to reconsider the conventional approach to designing the built environment and instead come up with environment-based, climate-conscious design strategies [3,4,5,6]. Combining performance criteria such as climatic factors with architectural design ideas and blending them into architectural and urban planning might lead to efficiently-performing architecture derived from its surroundings, and might, this way, contribute to mitigating the worst-case scenarios of climate change [7]. Through digital architectural design intertwined with environmental and structural engineering, buildings, as well as the urban environment in the continually changing microclimate, can be created as a reaction to natural forces [10]
