Research On Lighting Design Of Building Scheme Stage Based On Parametric Platform

In this paper,based on parametric design platform for the study,by building natural lighting as the research object,in view of the design personnel in the construction design stage to the demand of the building performance simulation optimization,summed up the general significance of architectural lighting performance parameterized simulation optimization process.Then,the application of the process in different lighting forms such as top lighting,side lighting and mixed daylighting is analyzed by means of concrete model or case.The specific research content has the following two parts.First,a general scheme based on parameterized design platform is proposed in the design stage of building performance simulation optimization process.This paper takes "control deepening" as the basis of work,and USES "feedback optimization" as the main means for simulation optimization.In terms of specific strategies,the initial variables and target functions are analyzed.Then with the help of a Grasshopper and building performance simulation and optimization plugin,realize the DAYSIM geometric parameters and performance simulation software,the Design builder interconnected,and based on the simulated data,high precision,short time consuming to calculate algorithm scheme optimization.Secondly,it verifies the application of parameterized simulation optimization process of general building lighting performance in a variety of building types.In this paper,different building types are selected as the examples of the study,and the specific application of the simulation and optimization process of building lighting performance is described.The input methods of various variables are explained in terms of geometric variables,materials and construction variables and operation variables.The performance evaluation index is combined to form the objective function.Take advantage of parametric platform to display Pareto front edge and its analysis of simulation optimization results.This article will focus on dynamic performance of parametric design,daylighting in different lighting form and the requirements of the use of a variety of architectural space lighting to study optimization applications,the content in the domestic research isless.At the same time,this article on the Rhinoceros and Grasshopper platform to invoke the DAYSIM,and then developed the daylighting simulation content can implement operation process,put forward the architectural design stage lighting performance parameterized simulation calculation of key nodes and applicable method.
