摘要
本研究首先以太阳辐射照度大于240 W/m^(2),室外空气温度高于29℃作为需要遮阳的设计条件,剔除全年均不需要遮阳的台站。从人体热舒适角度出发,基于生物气候图计算我国各个台站在不同气候区人体热适应模型下的过热和过冷时间比,基于此利用ArcGIS软件完成了全国遮阳潜力的分布趋势,将我国分为6个遮阳设计区:最佳区、适宜Ⅰ区、适宜Ⅱ区、适宜Ⅲ区、不适宜区、最不适宜区。最后,在每个遮阳设计区选取典型城市分析过热期遮阳需求与过冷期采暖需求所占比重,提出遮阳设计建议。该研究完成了不同气候条件下的遮阳和采暖潜力以及需求的量化,为建筑师在建筑设计初期提供遮阳设计指导。
A solar radiation illuminance greater than 240 W/m^(2),and outdoor air temperature higher than 29℃were set as the design conditions for shading in this study,with stations that do not need shading throughout the year are excluded.From the perspective of human thermal comfort,and based on the bioclimatic map,the time ratio of overheating and supercooling of each station in China under the human thermal adaptation model in different climatic regions were calculated.Based on this,ArcGIS software was used to complete the distribution trend of the national sunshade potential,and divide China into six sunshade design areas:the best area,suitable area I,suitable area II,suitable area IIl,unsuitable area,and the most unsuitable area.Then,typical cities in each sunshade design area were selected to analyze the proportion of sunshade demand in the overheated period and heating demand in the supercooled period,and propose sunshade design suggestions.This study completed the quantification of shading and heating potential and demand under different climatic conditions,providing guidance for architects in shading design at the initial stage of architectural design.
