日照问题是建筑总体布局和单体设计中不可忽视的因素。搞好日照设计,不仅要了解太阳辐射对生产和生活的影响,还要掌握太阳与地球之间的运动规律和计算太阳在天球上运行位置的数据。从而正确地利用和限制日照对建筑物的作用,合理地规划城镇、街道,选择建筑物的朝向、间距,设计适宜的采光口,安排恰当的遮阳构件以达到遮阳效果。现以位于湘鄂边界的石首市地理纬度和气象资料,探讨石首地区日照设计的有关问题,供设计中参考。石首市城区绣林位于北纬29°44′东经112°24′范围(表1),从多年气象资料记载,夏季气温高、温度大,持续时间长。七月份平均气温为26℃～30℃,最高气温为35℃～38.6℃(表2),太阳辐射强度按同纬度地区实测资料,最大值Jmax可达705千卡/米~2时,最热
The sunshine problem is a factor that can not be ignored in the overall layout of the building and the individual design. To do a good job of sunshine design, we must not only understand the effects of solar radiation on production and life, but also grasp the laws of movement between the sun and the earth and calculate the data on the location of the sun on the celestial sphere. In order to properly use and limit the role of sunshine on buildings, rationally plan towns and streets, select the orientation and spacing of buildings, design suitable lighting outlets, and arrange appropriate shade members to achieve shade effects. The geographical latitudes and meteorological data of Shishou City, located on the border of Hunan and Hubei, are being used to explore the issues concerning the sunshine design in the Shishou region for reference in the design. The embroidered forest in Shishou City is located at a latitude of 29°44′N and 112°24′E longitude (Table 1). According to meteorological data from many years, summer temperatures are high, temperatures are high, and the duration is long. In July, the average temperature is 26°C to 30°C, and the maximum temperature is 35°C to 38.6°C (Table 2). The solar radiation intensity is based on the measured data in the same latitude area. The maximum Jmax can reach 705 kcal/m~2.
