我国经济日益兴旺繁荣,城市建设迅猛发展。对于建筑用地日趋紧张,在居住区规划设计中都千方百计地提高居住建筑面积密度,力求节约用地。但采用缩小日照间距,降低居住建筑日照条件和居民生活环境质量,这是舍本逐末似不可取。房屋建筑布置,力求避免四周互相遮挡,留出必需的日照间距,保证阳光能直接照射到房间内。影响房屋间距的确定有很多因素,如通风、采光、卫生、防火和防噪等间距以及管线埋设、地面高差等的工程距离等等。为了创造适当的居住环境,在当前的经济条件 China’s economy is growing prosperous and prosperity, and urban construction is developing rapidly. As construction lands become increasingly tense, the density of residential buildings has been increased by every possible means in the planning and design of residential areas and efforts have been made to save land. However, the use of narrowing the distance between sunshine hours and lowering the sunshine conditions of residential buildings and residents’ living environment quality is not desirable. The layout of the houses is to be arranged so as to avoid obstructions around each other and leave the necessary sunshine spacing to ensure that sunlight can directly reach the room. There are many factors that affect the determination of the distance between houses, such as the distance between ventilation, lighting, hygiene, fire prevention and noise prevention, as well as the engineering distance of pipelines and ground elevation, and so on. In order to create a suitable living environment in the current economic conditions
