Performance-driven optimization of urban open space configuration in the cold-winter and hot-summer region of China

A Sustainable Design Strategy Based on Building Morphology to Improve the Microclimate of University Campuses in Cold Regions of China Using an Optimization Algorithm

“…For example, increasing the height (H) to width (W) ratio of streets can reduce the air temperature and solar radiation and improve the thermal environment in summer, but excessive wind speed will result in thermal discomfort [28]. In addition, a morphological layout that is suitable for the summer thermal environment may not have advantages in the winter [29]. In cases where different parameters have to be optimized simultaneously, Pareto optimization is commonly used.…”

“…e EPW and Dynamo were used to calculate the sunlight duration and solar radiation, which allows for changing the simulation parameters, such as the building type and the road width of the cluster. e climate data of Harbin (45.77°N, 126.68°E), which is a typical city in the cold region of China, was chosen as the reference; the data were obtained from the EPW [29]. e location information was used to calculate the sunlight duration and the annual direct and scattered radiation values.…”

Identifying key determinants for building energy analysis from urban building datasets

“…Yuan et al highlighted the effect of the urban morphologies on the urban heat island (UHI) effect and integrated a geographic information system and computational fluid dynamics for modeling the impact of urban morphology on the heat dispersion [13]. The wind field, speed, and shadow in the city have been proved to be highly influenced by the design parameters, e.g., open space and layout, of the urban morphology [14]. Solar radiation has been recognized as another important climate parameter that is significantly related to building energy demand and also potentially provides solar energy [15] while being highly dependent on the inter-building effect (IBE) (e.g., shading and roof design) in urban environments.…”

Revealing Urban Morphology and Outdoor Comfort through Genetic Algorithm-Driven Urban Block Design in Dry and Hot Regions of China

“…Urban climate is determined by a city's spatial structure, block texture, building form, open space layout, and so on [1]. Urban climate influences building cooling and heating loads, and outdoor thermal comfort, then influences the building performance [2], and it is therefore one of the most significant factors considered in urban design [3]. Sustainable urban design plays an important role in the improvement of the urban climate, pointing to the need for more climate-responsive environments [4].…”

“…At the stage of conceptual design, Caruso et al optimized building forms with the aim of minimizing the receipt of solar radiation by using the calculus of variations of mathematical theory [41]. Xu et al estimated the impact of open space on the urban micro-climate and validated the open space design strategies through performance-based optimization, however, which need further consideration of the impact of building form, street orientation, and so on [3]. Contreras et al used a genetic algorithm to conduct random variation and combination with building façade, roof, window type, glass type and shade coefficient as genes, to achieve the lowest building energy consumption [42].…”
