基于BIM的探索性建筑改造设计方法

The Exploratory Architectural Renovation Design Method Based on BIM

我国城市发展已经从增量时代转变为存量时代,大量的老旧建筑已经不能满足现有的需求。文章将计算性设计方法集成到BIM技术应用环境,提出旧建筑改造计算性设计方法,控制关键建筑设计指标,生成一组帕累托最优前沿设计性选项,为后续的评估和进一步的设计开发提供基础,为建筑改造生成探索性设计选项。研究侧重于强调建筑日照指标,结构变体数量以及生命周期成本,进而探索BIM技术和计算性设计在旧建筑改造方案设计中应用的可行性。

China’s major construction market has changed from the incremental era to the stock era,and a large number of old buildings can no longer meet the existing demand.This paper integrates computational design methods into the application environment of BIM technology,proposes computational design methods for the renovation of old buildings,controls key building design indicators,and generates a set of Pareto optimal exploratory options,which provides a basis for subsequent evaluation and further design development,and generates exploratory design options for building renovation.This paper focuses on building sunshine indicators,the number of structural variants and life cycle costs,and then explores the feasibility of BIM technology and computational design in the design of old building renovation schemes.
