Spatial information management system for building energy consumption

Abstract

Energy is a fundamental and critical component in modern global economy of a country. Industries, education, commercial facilities and people use the energy to enjoy a comfortable standard of living. Thus, energy supply and consumption are an important issue in national economies and quality of life. The inefficient electricity consumption management leads to incur the highest possible cost. Big consumer is billed by the utility not only on the total energy consumed, but also on maximum demand, power factor and time off use. Therefore, to respond to the challenges of increasing energy cost, this study is conducted using spatial or geographic information system (GIS) technology in assisting the Electrical and Telecommunication Unit of UiTM Shah Alam to manage the building energy cost. The GIS establishment and database management can practice 3-Dimensional mapping of energy consumption and demand location from the utilities record, and analyze the energy consumption according to UiTM Academic session. A prototype system is also generated for calculating a total of energy use for a month by using a graph and estimate building electrical bill in achieving energy efficiency. GIS is a powerful tool that could analyze energy use for a better cost-effective decision making.
