乡村住宅节能是城乡建设领域实现节能减排的重要途径之一,但在追求能耗降低的同时会出现舒适性降低、投资成本增加等衍生问题,因此需要考虑多 目标条件下的建筑设计模式研究.基于MOBO优化软件、NSGA-Ⅱ优化算法、EnergyPlus模拟引擎和多属性决策方法,建立多 目标优化导向的建筑设计模式构建流程及方法.并以西北寒冷地区乡村住宅为例进行应用分析,选择建筑能耗、室内热舒适性和投资成本作为优化目标,建筑形态参数、围护结构参数和室内热环境参数作为优化变量,最终得出兼顾不同目标导向需求的优化设计模式及技术模板.结果表明:全局综合性能最优方案的建筑节能率为54.0％、平均预测不满意百分率(APPD)提升率为57.6％、初投资成本增额182.40元/m2,与单目标优化得出的解相比,多目标优化能够通过权衡不同目标性能之间的矛盾得出更具可行性的方案,可为西北寒冷地区乡村住宅优化设计提供参考.
Research on the establishment of rural house optimal design pattern in northwest cold region under multi-objective conditions
Energy saving in rural housing is a critical pathway to achieve the energy conservation and emission reduction in the field of urban and rural construction.However,while pursuing reduced energy consumption,derivative problems such as reduced comfort and increased investment cost may arise.Therefore,it is necessary to explore the building design pattern research under multi-objective conditions.Based on MOBO optimization software,NSGA-Ⅱ optimization algorithm,EnergyPlus simulation engine and multi-attribute decision making method,it establishes a construction method for building design pattern oriented by multi-objective optimization.As well as,the application analysis is carried out by taking the rural house in the cold area of Northwest China as an example.It selects the building energy consumption,indoor thermal comfort and investment cost as optimization objectives,and building form parameters,envelope parameters and indoor thermal environment parameters as optimization variables.Finally,the optimization design pattern and technical template considering different target-oriented requirements are obtained.Results show that the building energy saving rate,APPD improvement rate and the increment of initial investment are 54.0％,57.6％and 182.40 yuan/m2 respectively for the global comprehensive performance optimal scheme.Compared with the solutions from single-objective optimization,the multi-objective optimization provides more feasible solutions by balancing the contradiction among different objectives,offering valuable insights for the optimal design of rural houses in the northwest cold region.
