办公建筑遮阳产品综合性能模拟与评价

COMPREHENSIVE PERFORMANCE SIMULATION AND EVALUATION OF WINDOW ATTACHMENT IN OFFICE BUILDINGS

该文旨在探究卷帘对夏热冬冷地区办公建筑采光和能耗的综合影响并确定影响卷帘综合性能的关键参数。首先,选取影响卷帘性能的6个参数:太阳辐射透过率、太阳辐射反射率、红外透射率、外侧发射率、内侧发射率和导热系数;组合得到560种遮阳产品,并利用EnergyPlus软件和Radiance软件对其进行全年动态能耗模拟和全年采光模拟;其次,通过调查问卷获得考虑办公建筑人员行为的遮阳时间表以及室内人员对眩光、自然采光和能耗的关注度占比;最后,综合考虑能耗、眩光和自然采光,创新性地提出综合性能指标(ED)对卷帘进行综合评价。基于该指标,确定影响卷帘性能的关键参数。研究结果表明,在夏热冬冷地区,太阳辐射透过率和太阳辐射反射率是影响卷帘综合性能的关键参数,当太阳辐射透过率在0.01~0.10范围内变化时,其对卷帘综合性能有积极影响。

This paper aims to explore the comprehensive impact of roller shade on daylighting and energy consumption of office buildings in range of hot summer and cold winter,and determine the key parameters affecting the comprehensive performance of roller shade.Firstly,560 kinds of roller shade are obtained by selecting the combination of 6 parameters affecting the performance of roller shade,and the annual dynamic energy consumption simulation and daylighting simulation are carried out by using EnergyPlus and Radiance;Secondly,through the questionnaire,the shading schedule considering the human behavior of office buildings and the proportion of indoor personnel’s attention to glare,daylighting and energy consumption are obtained;Finally,considering energy consumption,glare and daylighting,an innovative comprehensive performance index(Energy-Daylight,ED)is proposed to comprehensively evaluate the roller shade.Based on this index,the key parameters affecting the performance of roller shade are determined.The results show that in range of hot summer and cold winter,solar transmittance and reflecttance are two main factors affecting the comprehensive performance of roller shade.When the solar transmittance changes in the range of 0.01~0.10,it has a positive impact on the comprehensive performance of roller shade.
