基于零碳目标的建筑光伏空间布局优化技术研究
Optimization of building photovoltaic spatial layout based on zero carbon target
摘要：
零碳建筑侧重在高容积率、紧凑空间、被动遮挡条件下的光伏空间布局。本文对建筑各表面开展了网格化太阳辐照量计算，提出了建筑光伏系统的适宜安装区。基于三维可视化模型，根据各表面太阳辐照量，对光伏系统发电量进行了精细化修正。优化布局后可充分发挥各表面的光伏发电潜力，提高单位装机功率的发电时长，显著提高技术经济性。
Abstract：
Zero carbon buildings focus on the photovoltaic space layout caused by high plot ratio, compact space and sheltered area. This paper carries out the grid solar irradiation calculation for each surface of the building, and puts forward the suitable installation area for the building photovoltaic system. Based on the three-dimensional visualization model, the power generation of the photovoltaic system is refined and modified according to the solar irradiation on each surface.Based on the layout optimization, the power generation potential of each surface as well as the power generation time per unit installed power will be extended significantly, so as to improve final economic benefits.
