摘要

全球人口的快速增长导致城市密度成倍增加。随着城市密度的增加,城市峡谷的环境质量也随之下降,从而导致建筑物的相关能耗增加。目前,全球 70% 的能源消耗来自城市。解决这一问题的有效办法之一是让更多的太阳能进入室内,从而充分利用日光和太阳辐射热量。因此,本文提出了一种新颖的方法,通过开发和应用基于进化计算的定制算法,将城市环境和建筑内部的日光优化结合起来。这最终将使更多的日光渗入城市峡谷(垂直日光照度(VDI)),进而改善室内视觉舒适度(有用水平照度水平(HIL))。这还可以减少建筑物的相关照明和供暖(冬季)能耗。此外,研究室内和室外照度水平之间的相关性,旨在弥合城市规划和建筑尺度上日光需求之间的差距。通过对设计变量的计算模拟,进行了基于多目标进化算法的评估。这就确定了每种城市形态对室内外日光获取的影响程度。据此,提出了不同设计因素的最佳范围。

An Evolutionary Computing Approach For Simultaneous Daylight Optimization in Urban Environments and Buildings Interiors

An Evolutionary Computing Approach For Simultaneous Daylight Optimization in Urban Environments and Buildings Interiors

Rapid population growth globally is resulting in urban densification exponentially. As cities become denser, the environmental quality of urban canyons reduces, resulting in an increase in associated energy use in buildings. Currently, cities are responsible for 70% of the world’s energy consumption. One of the efficient solutions to address this issue is allowing more solar access into interiors and thus making the most of daylight and solar heat gain. Accordingly, this paper presents a novel approach to integrate daylight optimization in both urban environments and buildings’ interiors via the development and application of a custom algorithm based evolutionary computation. This ultimately allows more daylight penetration into urban canyons [vertical daylight illuminance (VDI)] and, subsequently, improves indoor visual comfort [useful horizontal illuminance level (HIL)]. This can also reduce the associated lighting and heating (during winter) energy use of buildings. Furthermore, investigating the correlation between indoor and outdoor illuminance levels aims to bridge the gap between daylight requirements at the urban planning and building scale. A multi-objective evolutionary algorithm-based assessment using computational simulation of design variables is conducted. This determines the extent to which each urban morphology can affect daylight access in both indoor and outdoor environments. Accordingly, the optimal range for different design factors is suggested.

期刊介绍: International Journal of Environmental Research is a multidisciplinary journal concerned with all aspects of environment. In pursuit of these, environmentalist disciplines are invited to contribute their knowledge and experience. International Journal of Environmental Research publishes original research papers, research notes and reviews across the broad field of environment. These include but are not limited to environmental science, environmental engineering, environmental management and planning and environmental design, urban and regional landscape design and natural disaster management. Thus high quality research papers or reviews dealing with any aspect of environment are welcomed. Papers may be theoretical, interpretative or experimental.
