绿色建筑节能在传统建筑的基础上设置了生态设施与节能设施,改换了建材与建筑部品,这无疑需增加建设成本。这类投入的增加可以获得生态环保效益,可以降低运行成本,也是人们所期望的,但是对此分析不应停留在设计目标与理论期望的阶段,应从绿色建筑的全生命周期来分析并通过实际运行数据给出结论,因此绿色建筑工程必须拿数据说话! Green building energy-saving In the traditional building based on the ecological facilities and energy-saving facilities, building materials and building parts replaced, which undoubtedly increase the cost of construction. The increase of such investment can obtain the benefit of environmental protection, which can reduce the operating cost and is also expected. However, the analysis should not stop at the stage of design goal and theoretical expectation. It should be analyzed from the whole life cycle of green building, Operating data gives a conclusion, so green building works must take the data to speak!
