A Software Calculator for the Ecological Evaluation and Simulation of Building Construction Engineering

摘要

Recently, emergy method has already tried to use on evaluate the green building. However, the popularity of emergy analysis method also needed to become more intuitive and simple. While many items of the existing green building assessing standard are not easy to quantify and they should take subjective methods to calculate, emergy seems can make up the defect of it as an objective scale. In this paper, building information modeling (BIM) technology and the emergy analysis method are merged to realize the ecological evaluation of the building. By the BIM tools, trimensional visual quantity automatic calculation software, bill of quantity software, we extract resource and energy consumption quantity of the building. Then we designed an assessment calculator by GUI function programming in MATLAB, it can be carried out the weighted calculation with the coefficients in emergy table which is built in the calculator. Then we can get the amount of the building and determine whether it meets the sustainable development of the emergy index. By the empirical study on the practical building, the integrated of emergy, emergy method and BIM technology, the calculative simulation could be realized. Furthermore, building construction ecological evaluation should substitute the comprehensive assessment.
