Study on the Evaluation Method of Green Construction Based on Ontology and BIM

Algorithm 1

Pseudocode description of the proposed methodology.

	Evaluation algorithm for green construction.
(1) In: Evaluation Indicator of green construction.
(2) Out: Evaluation scores and specific indicators needing improvements
(3) Start
//the first stage
(3) Synthesize the green construction evaluation indicators and criteria
//the second stage
(4) Develop Ifc-extended attributes P () to represent the property sets.
(5) Develop Ontology-based parameter E () to represent the evaluation indicators.
(6) Map (P/E, {}/{})
//the third stage
(7) Build the knowledge base
//the fourth stage
(8) Generate the evaluation score of all indicators Ei based on values from K
(9) Retrieve specific indicator with ei < t which needs to be improved and optimized//t is the lower limit for the evaluation result.
(10) End
