Dominator tree data flow cognitive analysis for green public building design

摘要

In accordance with Green Building Evaluation Standard and Green Building Technology Guidance, this paper selects the evaluation contents related to design scheme, establishes the evaluation index system optimizing the green building design scheme, based on this, introduces the improved data flow analysis method (three-demarcation method) to determine the weights of various evaluation indexes, adopts triangular classification building design examples to establish the data flow control flow graph for data test, establishes the data flow analysis of building design by aid of its dominator tree relation, and establishes the dominance relation set between building design variables thus to select the optimal scheme. Finally, it proves the effectiveness and practicality of the evaluation system based on live examples.
