Application of demand side management (DSM) as strategic option to reduce energy consumption and cost for commercial building

Abstract

Demand Side Management (DSM) is an integral part of planning, implementing and monitoring of those utility activities designed to influence consumers in ways that will produce desired changes in quantity, pattern and the utility load shape. In DSM three concepts can be clearly identified: Energy Efficiency, Energy Conservation and Demand Response. Energy Efficiency refers to permanent installation of energy efficient technologies. New technologies of lightings represent energy efficient technologies which is a part of DSM program. This thesis focuses on the usage of lighting in commercial building. Lighting consumes approximately 15% of the energy usage in residential buildings and 30% in commercial buildings. The lighting industry has made substantial improvements in virtually all aspects of the total lighting system from new and improved lightings, ballasts, and luminaries to state-of-the-art energy control and management systems. Examples of lightings technology are: T8, T5, Light Emitting Diode (LED), Incandescent Lamp and Compact Fluorescent Lamp (CFL). Each type of lighting offers different energy savings and cost. This thesis compares different lightings in terms of cost and payback period. Simulations are done using Matlab software. It is discovered that the best lighting option depends on usage hour and payback period.
