Abstract Humanism and Technology are not incompatible; they can actually bring about each other. This research attempts to realize the humanistic idea of sustainable development through the application of green technology. The language center of Alethia University thereby transforms smoothly from analogue era into digital era and achieves a green revolution of media application. The language center follows the 5R principles of environment friendliness, namely, Rethink, Reduce, Repair, Reuse, Recycle and deliberately replaces audio tapes with flash drives, substitutes whole sets of computers for compact USB devices, introduces satellite technology to revolutionize traditional visual sources, and above all, replaces ingratiating sub-cultural trends with refined, elegant culture. All these transform the center into an environment friendly paradise. This research goes into the category of action research. Action researchers use empirical actions to initiate useful research and bring up illuminating suggestions. Nowadays, as a result of global warming, the sustainable development of human society is threatened. This research, through the renovating action of the language center, proves that cherishing facilities and reducing energy consumption can likewise enable students to broaden their horizons and embrace refined cultures. Currently, universities in Taiwan are not easy to run; problems of administration and instruction arise in succession. This research tries to set an example for the university faculty and staff. Hopefully they can analyze the problems they confront and then find strategies to solve them step by step. After that, they can further share their experiences with one another and then work together to improve the discomforting status quo of their universities.
