旧城改造工作中的光遮挡环境问题凸现,由此引发的日照问题逐渐受到广泛关注.已往的日照环境影响评价大多针对拟建项目对周围原有项目的影响,而忽略了新建项目可能受到潜在的光遮挡.本文从连续日照时间的角度,重点对新建高层建筑可能会受到的日照环境影响进行分析,尝试提出一种日照问题的方法"零项目"日照环境影响评价法.In the reconstruction of old cities,the problem of sunlight blocking out by higher buildings has caused more and more attentions,and it becomes a new concern of real estate′s environment impact assessment.However,the existing sunlight environment assessment methods used to be focused more on the sunlight shielding by new buildings to the existent ones while it ignores the potential sunlight shielding the new building may have.Based on the sunlight duration,this paper focuses on the analysis of potential sunlight shielding that a new programme may have and attempts to find an effective method for the sunlight environment assessment
