“…However, this association neglects to realize that urban flow is not a confined flow and is free to move up and over, or around, the associated buildings. This is supported by the observation of Wang et al that shows for two adjacent buildings, with flat roofs, that flow speed over the roof generally increased in a converging inlet arrangement and decreased for a diverging inlet configuration (Wang, Cot, Adolphe, Geoffroy, & Morchain, 2015). Diverging canyons are more effective at accelerating the flow because of the wind blocking effect that is more appreciable for a converging building configuration (Stathopoulos, Blocken, Moonen, & Carmeliet, 2008).…”

“…Each plane is divided into several sub-areas according to the velocity scale ( Figure 1(c)). For a given surface, each sub-area is multiplied with its corresponding cubic average velocity and then the multiplications can be summed up into the value of M [32].…”

Urban wind development is gathering energy and passion these years and is good for sustainable cities. This chapter tries to evaluate wind energy potential with study of urban form in a block scale (500 m Â 500 m). CFD method is used for wind flow simulation. CFD parameter settings were validated and evaluated with wind tunnel experiment. Simple building forms (1-3 buildings) were tested for exploring the impact of building form on wind potential. Space over roof is proved to be most effective and practical position for developing wind energy in the urban environment. Ideal urban forms were tested for evaluating the impact of one single morphological parameter on wind potential over roof. Real urban forms were then evaluated and compared in order to reveal the impact of different urban form parameter on wind potential. Urban form unit models are then considered to understand the impact of a certain urban form feature on wind potential. Finally, a block model in Beijing is given for urban wind evaluation case study, including wind potential evaluation of every building roof in the model, wind turbine position evaluation, and economical cost analysis.

“…Windows that only open halfway, such as double-hung and sliding windows, are only half as effective for ventilation as they are for daylight. Some casement windows and Jalousie windows, however, can open so wide that effectively their entire area is useful for ventilation [62,65].…”

Wind ventilation is an efficient design strategy for the natural cooling system (NCS) in humid climates. The building forms can generate different pressures and temperatures to induce natural ventilation. This study has been carried out in Rasht city, Iran in 2017. The method was performed using a computational fluid dynamic (CFD) approach simulation to study variance between the proposed and the actual results of a design. The goal of the study is to assist architects to design optimum building form for natural ventilation. Hence, the purpose of this study was to investigate the effect of the form on natural ventilation. On this basis, wind flow simulation was performed using Design Builder Version 4.5. In this paper, the present usage of natural ventilation of rural residential buildings in Rasht area the application of this methodology. Initially, wind simulation was carried out based on actual building specifications. Then the proposed L-shaped extension was added to the building. The results showed that if the rectangular form is turned into an L shape, it can offer a better flow pattern for wind in all rooms, but the speed will be reduced.
