建筑立面造型中智能遮阳系统的节能设计

Energy-saving Design of Intelligent Shading System in Building Facade Modeling

摘要:

针对智能遮阳系统与建筑立面造型脱节、节能潜力未充分释放的问题,文章提出一种"形态-性能"一体化设计方法,将智能遮阳作为主动造型要素纳入参数化生成流程,并构建基于环境反馈的精细化控制策略,建立了"设计—模拟—优化"的闭环工作流。以西安某办公建筑西立面改造为例进行验证,结果表明:相较于基准状态,优选方案可使室内温度峰值降低3.5 ℃、估算全年冷负荷降低约18%,同时有效控制眩光。

Abstract:

In response to the problem of the disconnection between intelligent shading systems and building facade design, and the insufficient release of energy-saving potential, this article proposes an integrated design method of "form performance", which incorporates intelligent shading as an active shaping element into the parameterized generation process, and constructs a refined control strategy based on environmental feedback, establishing a closed-loop workflow of "design simulation optimization". Taking the renovation of the west facade of an office building in Xi'an as an example for verification, the results show that compared to the benchmark state, the optimal solution can reduce the peak indoor temperature by 3.5 ℃, estimate a reduction of about 18% in annual cooling load, and effectively control glare.
