Research On Parameterized Overall Design Method Of Green Building Based On Generation Logic Comparison And Selection

This research is based on the general project of National Natural Science Foundation of China "Research on parametric generation theory and overall design method of green building"(fund No.51378049).In recent years,with the continuous innovation of building generation methods and the rapid development of parametric simulation platform,the theory of green building parametric multi-objective optimization design needs further study.According to "systematic thinking",this paper combs the ideological connotation of green building,summarizes the dynamic energy space-time concept of green building,and studies the logical framework of green building generation design methodology.Through the comparison of several generations of design methodology systems,and the integration of the advantages of practical method,technical method and normative method,deepen the research on the overall design theory of green building.Based on the "systematic thinking",the multi-objective optimization generative logic is studied in layering,contrast and integration,and the effectiveness of the comparison program is verified by the simulation results of the simulation platform.The specific contents include: 1)firstly,based on the time axis,this paper summarizes the basic theory and practical cases of several generations of green building parametric generation methods,and finds the limitations of the integration method of green building parametric generation design logic and green performance multi-objective evaluation method.2)Through the further study of the process and four basic elements that affect the parametric design optimization of green building,it can be found that the existing traditional evaluation methods under the mechanical theory and linear thinking can not overcome the interference of parameter relevance and mutual exclusion on the integration and evaluation system.3)The introduction of "systematic thinking" provides a new research idea for green building parametric multi-objective optimization.In order to effectively avoid the interference of parameter relevance and mutual exclusion on the evaluation results of objectives,the research on the correlation between influencing factors and optimization objectives in the existing multi-objective optimization research is transformed into the comparison and selection research on the applicability of optimization generation logic.According to the existing green building parametric design process,combined with the analysis of multi-objective integration method of green building generation design,this paper studies the comprehensiveness and accuracy of green building generation design decision-making and the ease of operation of the process from three aspects: simulation tool intervention,parameter program set and program design logic.4)On the basis of the existing experience and data of standardization,the specific evaluation index system of optimization objective and the operation procedure parameters of evaluation program are studied.5)According to the selected optimization value and parameter data,the comparison experiment of the designed optimization program is carried out.Taking the award-winning project i-Yard 2.0 of SDC Solar Decathlon China as an example,the effectiveness of the proposed multi-objective optimization program comparison method is verified from two aspects of skin and structure level optimization.The conclusion of this paper shows that the green building parametric design method based on the generation logic comparison can effectively improve the comprehensiveness and accuracy of the parametric design decision-making,as well as the ease of operation and integrity of the process,and can provide the basic theoretical basis for the green building parametric generation and overall design method research.
