Abstract: Currently, green computing technology is one of research hotspots. The energy saving, environmental protection and conservation are the goal of the green computing. As the construction of low carbon living environment is important one annulus, green computing has become a new computing model of promoting the progress of science and technology and social sustainable development. As the focus of international competition and the commanding heights, green computing far-reaching influence on a countrys political,economic and social security and other aspects. However, there is relatively rare work on the construction of College Green computing environment. Therefore, the problems of laboratory computer specialty in our college are analyzed with this objective and the possibility of constructing green computing environments is presented in this paper. Thus, our school building green computing environment of the scheme and the corresponding measures were introduced in the technical background of cloud computing.
