热景观视角下既有教育建筑外遮阳设计研究

RESEARCH ON EXTERNAL SUNSHADE DESIGN OF EXISTING EDUCATIONAL BUILDINGS FROM THE PERSPECTIVE OF THERMALSCAPE

为获得既有教育建筑遮阳改造后的室内环境数据并探究其是否存在缺陷,以及进一步完善热景观理论与节能适应设计方法,以上海地区两栋教学楼为例,对教室空间进行光环境、风热环境实测,分析并比较不同遮阳形式对室内环境的影响。利用Grasshopper平台进行参数化建模,计算各形式遮阳构件的最佳安装参数。结果表明:水平遮阳在室内光热环境方面的表现优于穿孔板;水平旋转式外遮阳具有较大的节能潜力与较好的适用性;穿孔板节能效果不显著。最后从热景观营造角度对既有教育建筑外遮阳改造提出建议。

In order to obtain indoor environmental data and explore whether there are defects in the shading renovation of existing educational buildings,and further improve the thermalscape theory and energy-saving adaptation design methods,taking two teaching buildings in Shanghai as examples,the light and wind thermal environments of the classroom space were measured,and the effects of different shading forms on the indoor environment were compared.Utilize the Grasshopper platform to parameterize modeling of the main spaces and common shading forms,calculated the optimal installation parameters of various shading components,analyzed and compared the environmental and performance performance performance.The results show that horizontal shading performs better than perforated panels in indoor light and thermal environments,the horizontal rotating external sunshade has great energysaving potential and good applicability,the energy-saving effect of perforated panels is not significant and has a significant impact on indoor thermalscape.Finally,suggestions are made for the external shading renovation of existing educational buildings from the perspective of thermalscape creation.
