Integrated Energy Management of Residential Halls at University of Dhaka by Using Energy Efficient Appliances and Solar PV System
This paper analyses the electrical energy consumption of two residential halls at University of Dhaka and design the best approach to diminish the electrical energy consumption and reduce the carbon emission and achieve efficient energy utilization in the halls. Fazlul Haque Muslim Hall and Dr. Mohammad Sahidullah Hall were selected for a detailed study of electricity consumption. Series of data were taken to estimate the electrical energy consumption and the electrical energy losses across different loads. Afterwards with the results of electrical usage, an energy stability was made by considering the energy efficient electrical appliances along with a solar photovoltaic system to reduce the electrical energy wastage and reduce the carbon emission to maintain the environment clean. Overall energy losses can be minimized up to 40% and 41% at Fazlul Haque Muslim Hall and Dr. Mohammad Sahidullah Hall respectively with new energy efficient devices. A total of 43% and 44% energy consumption can be reduced at Fazlul Haque Muslim Hall and Dr. Mohammad Sahidullah Hall with the proposed new energy management system that implies to utilize solar energy using solar photovoltaic. The emission of carbon reduction estimate was about 302 tons and 290 tons of CO2 at Fazlul Haque Muslim Hall and Dr. Mohammad Sahidullah Hall respectively. The payback period of the investment to replace the electrical appliances with energy efficient appliances and to install a solar photovoltaic system is 2.45 years.
