基于被动式理念的高层综合体建筑节能设计策略--以齐鲁创新谷某高层办公综合体为例

Energy-saving Design of High-rise Complex Based on Passive Concept:Analysis of a high-rise office complex in QILU Innovation Valley

随着现代建筑能源消耗总量的增加和人们舒适性需求的不断提升,探讨合理的被动式技术策略,有效地提升建筑室内舒适度,降低建筑能耗尤为重要。以齐鲁创新谷某高层办公综合体为例,基于地域性气候与建筑功能分析,从规划布局、建筑形体设计、热缓冲空间设计和遮阳一体化设计4个层面探讨适用于寒冷地区高层综合体建筑的被动式设计策略,并借助计算机模拟软件对设计策略进行了定量化分析,选择最佳方案,探讨既满足建筑功能空间需求,又可改善建筑室内外舒适性和降低能耗的设计策略。结果表明:分离式布局和曲线形体有效改善了建筑场地微气候;加入热缓冲空间后建筑单位面积能耗降低约14%;遮阳一体化策略有效改善了室内光环境品质,降低了南向办公空间单位面积制冷能耗约45%。

With the increase of building energy consumption and the improvement of people’s comfort demands,it is particularly important to explore reasonable passive technology strategies to improve building indoor comfort and reduce building energy consumption.The paper takes a high-rise office complex in QILU Innovation Valley as an example,based on regional climate and building functional analysis,from four levels including the planning layout,the building form design,the thermal buffer space design and the integrated shading design to explore the passive design strategy of high-rise building complex in cold areas,and use the simulation software to quantitatively analyze and select the best plan.Discussing the design strategy that not only meets the needs of building functional space,but also improves indoor and outdoor comfort and reduces energy consumption.The results show that,the separated layout and arc shape improve the microclimate of the building site;the energy consumption per unit area of the building is reduced by about 14%after the addition of the thermal buffer space;the integrated shading strategy effectively improved the quality of the building’s indoor light environment and reduced the cooling energy consumption of the south-facing office space by about 45%.
