以“火星救援”与“二手宇宙”两个虚拟案例入手,对建筑学里的性能认识进行了辨析,分析了建筑学性能研究中的表现性。通过比较性能与效能的不同意义,分析有效性和系统失效,反思建筑学体系完整化的思想方式,提出:对性能的建筑学认知应该扩展至建筑使用改变的状态与未来建筑系统改变的语境里。 Starting with two virtual cases, “Mars Rescue” and “Second-hand Universe”, this paper analyzes the performance awareness in architecture and analyzes the performance in the study of architecture performance. By comparing the different meanings of performance and effectiveness, this paper analyzes the validity and the system failure, and reflects on the way of thinking of the completeness of the architecture system. The author points out that the cognition of performance architecture should be extended to the changing state of building use and the future change of building system Habitat.
