Based On Performance Driven Building Environment Performance Optimization Design Method Research

In the context of the current low-carbon development and green building,the architectural design presents a trend of low carbonation and complex functions,while the traditional architectural design method has been congenitally deficient by the design process of individual subjective feelings and experience judgment.Repeated design,rational and quantitative factors in the design,the design results depend on the main members,the lack of design interaction and collaboration,design quality can not be guaranteed.Based on the shortcomings of traditional architectural design methods and the integration of parametric design ideas,combined with the experience of optimizing the design of relevant disciplines,this paper constructs a design method suitable for building design based on the optimization of building environment performance and performancedriven design.Driven building environment optimization design method.This method is based on the performance-driven building environment design platform as the core,respectively,to join the experimental design method,multi-objective decisionmaking method to enhance the adaptability of the design method,and different design scenarios for the object of the hierarchical discussion:1)Taking the optimal design problem aiming at the construction window width and the indoor light environment of the building,the application of the optimal design method in the common design scene is expounded,and the optimal light environment Good shape and position.2)Based on the design problem of building energy consumption index and construction cost index,this paper expounds the application of design experiment and optimization design platform in the design scenario of a large number of variables,and obtains the construction energy consumption index in the case setting The optimal value of the variable in the case of the corresponding variable value of the law.3)The optimal design problem of the three parameters related to the wind environment in the design of the actual project is described.The multi-objective problem decision is put forward in the design scenario where the single optimal solution needs to be determined inthe face of multi-objective optimization problem And the optimal application scheme of the optimal design environment is obtained.Unlike the uncertainty of the individual subjective experience of the designer in the traditional design and the judgment of the empirical judgment,the final conclusion of the discussion of these cases is the precise design rule or design result,to some extent,the performance-based The optimal design method of building environment will be the feasibility and validity of the idea of ??coupling multiple design goals in the scheme design into a multi-objective optimization problem.In general,this paper aims to provide a new design idea and method for architectural design,try to draw lessons from other disciplines and combine architectural design,design,evaluation and decision-making together to form a flat design pattern.The future study of the optimal design of the building environment provides a basis.
