Multi-objective Optimization Of Spatial Form Of Wuhan High School Building Based On Building Energy Consumption And Natural Lighting Performance

In recent years,with the continuous promotion of green campus construction,campus energy consumption and indoor environment have received widespread attention.As the most frequently used building on campus,the control of energy consumption and indoor environment is crucial to creating a good campus environment.High school buildings have a great potential for energy saving and indoor environment enhancement due to the special characteristics of the population and time of use.As the primary consideration in the planning stage,the building form has a significant impact on the control of energy consumption and the enhancement of indoor environmental comfort.The aim of this paper is to build a multi-objective optimisation process for teaching buildings from the spatial form of high school teaching buildings,in order to reduce the energy consumption of Wuhan high school teaching buildings while improving the natural light performance and promoting the construction of a green campus.Firstly,this paper presents a detailed analysis of the theories related to energy consumption and natural lighting,the spatial characteristics of teaching buildings,and the factors affecting the morphology of teaching buildings,and elaborates on the multi-objective optimisation theory to provide a theoretical basis for the following multi-objective optimisation study.Next,this paper analyzes the morphological parameters of Wuhan high school buildings and collects and organizes relevant specifications,summarizes the common spatial morphology of Wuhan high school buildings and their parameter value domains,constructs a model of the building and simplifies it,and provides a model basis for the following optimization;then,it analyzes the influence of morphological parameters on the optimization objectives through the control variable method,and screens out the parameters with high correlation.The parameters with high correlation are selected and the range of values and simulation steps are determined to provide a parametric basis for the multi-objective optimisation experiment.Finally,the multi-objective optimisation process is based on the energy consumption and natural lighting performance of the Wuhan High School building.A parametric model of the school building is established based on the selected morphological parameters and simplified model,the simulation parameters and the optimisation objective function are set,and the multi-objective optimisation solution is carried out by a genetic algorithm.After 30 generations of optimisation,convergence is achieved and the set of Pareto frontier solutions is obtained.The set of excellent non-dominated solutions is finally obtained by screening the relevant specifications and target performance bounds,and the solution with the most balanced target performance is selected as the preferred solution.The design strategy is proposed to provide reference for the design of the Wuhan High School.
