Governments and organizations around the globe are increasingly searching for ways to reduce pollution from their sectors, such as greenhouse emissions, with a significant focus on the use and implementation of sustainable RE generation. A large portion of renewable energy (RE) work has been devoted to Photo-Voltaic (PV) systems using solar energy to generate electricity to provide both electrical and thermal charges as the abundance, free and clean characteristics of this RE source cause no disturbance or carbon emissions to the environment. Building Integrated Photovoltaic (BIPV) systems have developed tremendously in Malaysia in recent years as an application of PV technology and have been shown to help buildings partially fulfil the load as a feasible RE generation technology. In this paper, the efficiency and feasibility of BIPV application in Swinburne University of Technology Sarawak is investigated. Weather details such as air temperature, relative humidity, daily solar radiation, and the earth temperature in the university will be collected and analyzed. Different BIPV solar power systems are designed and simulated technically through modelling and simulation on related software. The analysis revealed that Feed in BIPV system is consider as the most promising way to achieve the target of saving. The maximum yearly consumption of the building will be 320000 kWh. By considering the BIPV system is connected to the grid, there will be extra 39715 kWh of production being fed back to the grid each year which gives an earning of RM11915 each year. Besides, the investment ratio will be 33.9% and the payback period for the entire BIPV system will be 14 years.
