Application of sustainable and renewable energy generation initiatives and architectural design solutions can help in making any educational campus energy-efficient and sustainable. These initiatives and solutions are helpful to conserve energy in the built structures and at the same time generate additional energy at the master plan level. The scope of research encompasses the COMSATS campus in Islamabad. In-depth study and research is done, to highlight the significance of application of green design solutions like green roof on an existing building to make it energy efficient and thermally comfortable. The project focuses on different modes of renewable energy generation and conservation of energy by applying appropriate green and sustainable techniques. A comparative study for different architectural design solutions with minimum cost and maximum advantages to reduce heat gain through building envelope that is the walls, the roof and windows of the buildings has been provided. At the same time suggestions have been made to generate additional energy through renewable sources and by application of latest technology.
