“…-A faster numerical simulation method was developed for large urban or regional scales. A few studies (Wang et al, 2021;Xu et al, 2023) mentioned other methods with less detailed modeling, such as the Porous Media Model, Fast Fluid Dynamics, and outdoor Multizone Model, and these methods reduced computational costs. In the case of Bangkok, which consists of uneven groups of buildings and complex buildings, these methods encounter difficulties.…”

“…In this context, urban canyons are defined by two fundamental properties: the heightto-width ratio (H/W) and the longitudinal axis orientation [26][27][28]. It has been demonstrated that these properties directly affect solar access and shading strategies, wind frequency, and heat exchanges that control surface and air temperatures [22,25,29,30]. As a result, they not only influence the OTC for individuals but can strongly impact the thermal comfort within indoor spaces, energy consumption, and cooling and heating demands [19,[31][32][33][34].…”

“…Simulation methods such as computational fluid dynamics (CFD) or fast fluid dynamics (FFD) allow architects and engineers to numerically evaluate and hence better understand the environmental implications of chosen design alternatives onto the surrounding such as potential buildings and blocks. However, these simulations are not necessarily accessible or feasible for early designs [1] especially in instances where multiple cases are being simultaneously investigated such as with parametric design workflows. CFD simulations are computationally expensive and often require experts to set up and run.…”
