With the improvement of living standards, people are more and more eager to improve the efficiency of energy conservation and emissions reduction of buildings. Pursuant to this, the application of BIM technology in the water supply and drainage engineering of green buildings is proposed. Firstly, the BIM model is built to draw the axis network and axis height and transform the spatial position of family components, which is conductive to addressing the problem of the loss of engineering information. Then, the energy-saving pathways of green building water supply and drainage projects are analyzed, Concretely, the drainage energy consumption can be reduced by decreasing the overall head of the water pump. The pipe resistance and drainage efficiency can be respectively reduced and improved through reasonable selection of parallel drainage pipelines. Also, the principle of "avoiding the peak and filling valley" can be adopted to reduce pump operation in peak period and water draining in valley period, thereby saving drainage cost. By optimizing the control strategy of the drainage system and improving the utilization rate of water resources, the final results of the study show that BIM technology can realize 69% energy saving of the total savings in water supply and drainage engineering of green buildings, decrease cost consumption and improve the quality of water supply and drainage system, so as to make full use of limited water resources to achieve the effect of energy conservation and emission reduction.
