摘要
为了降低建筑物能量消耗,助力建筑物被动式风环境节能,研究了基于BIM技术的建筑物被动式风环境节能优化方法。有效预处理建筑物CAD图纸,并将其输入到Revit软件中,构建建筑物BIM模型,经Lumion软件加载与渲染后,获得纹理清晰的建筑物BIM模型;使用建筑物能耗模拟引擎OpenStudio、Phoenics风环境软件构建被动式建筑风环境能耗物理模型,分析建筑物表面风环境;以窗墙比、保温板厚度作为被动式风环境节能优化的节能因子,构建建筑物制冷与采暖能耗最低两个适应度函数,经非支配排序遗传算法多目标优化求解后,输出最优建筑物被动式风环境节能优化方案。实验结果表明:该方法可以实现建筑物被动式风环境节能优化,节能优化后建筑物能量消耗明显降低。
In order to reduce the energy consumption of buildings and help the energy conservation of passive wind environment of buildings,the energy conservation optimization for passive wind environment of buildings based on BIM is studied.The building CAD drawings are effectively preprocessed,inputting them into Revit to build the BIM model.After loading and rendering by Lumion software,the BIM model with clear texture is obtained;Building energy consumption simulation engine OpenStudio and Phoenix wind environment software are used to build a physical model of passive building wind environment energy consumption and analyze the building surface wind environment;Taking window wall ratio and the thickness of insulation board as the energy-saving factors for the energy-saving optimization of passive wind environment,the two fitness functions with the lowest energy consumption of building refrigeration and heating are constructed.The optimal energy-saving optimization scheme of passive wind environment of buildings is output after the multi-objective optimization solution of non-dominated sorting genetic algorithm.The experimental results show that this method can realize the energy-saving optimization of building passive wind environment,and the building energy consumption is significantly reduced afier energy-savingoptimization.
