Green computing (also called green technology) is the use of computers and other computing devices/equipment in energy-
efficient and eco-friendly ways to conserve energy and reduce climatic change to its barest minimum. The frequent use of various
computing devices such as desktop computers, mainframe computers, data centres, and other electronic gadgets at tertiary institutions by a very large number of both staff and students result in energy being dissipated at regular intervals which may lead to climatic change and global warming that are hazardous to human health. Warmer temperatures over time
can change weather patterns and disrupt the usual balance of nature thereby posing many health risks to human beings and all other forms of life on earth. In this work, object-oriented analysis and design technology (OOADM) and unified modelling language (UML) tools were employed to develop a template for the application of green computing at Nigerian tertiary institutions. The two UML tools used: use-case and activity diagrams, show the various actors involved in the usage of green computing at tertiary institutions and the sequential steps required by each of the actors in using the green computing in his/her domain, respectively. The template well adopted by all the tertiary institutions and other establishments in Nigeria will help to conserve energy and reduce climatic change drastically, thereby creating a healthy environment.
