Abstract：
How to quantify the impacts of construction on resources, energy and environment is the key during the course of evaluating green construction. The impacts can be valued in a certain approach, and the value of cost becomes the basis of assessing green level of construction. The cost of consumed resources and energy was calculated according to actual consumptions and prices of various materials. The cost of actual loss of environment caused by construction was calculated according to sufferers’ willingness to accept compensation, or was assessed by professional department. Thus the actual green cost of construction was figured out about finished projects, on the other hand, the budge cost was calculated after adjusting prices by analyzing engineering budget. The deviation between actual cost and budge cost objectively reflects the green level of construction.
