EFFECTIVE BUILDING ENERGY MANAGEMENT SYSTEM

The energy management is crucial in the present time, as proper energy utilization
will improve industry competitiveness and ensure a more sustainable energy in future.
The focus of this project is on building's energy management system where the main
purpose is to use of energy efficiently and reduce energy consumption. There are
several factors which contribute to the energy consumption of buildings in Malaysia
butthe major factors are lighting as well as cooling. In 9th Malaysian plan, the aim is
to ensure that efficient utilization of energy resources and minimization of wastage;
and the focus will be on energy efficiency initiatives, particularly in the industrial,
transport and commercial sectors as well as in government buildings. Software to
estimate cooling load has been produced and in many ways will help a lot in
identifying the energy use for a particular area. A prototype of an area which is well
equipped and system for energy efficiency and saving is produced. The system is
used for controlling the energy consumption of lighting and cooling. For lighting
system, the use of occupancy sensor for controlling the on and off of the lights will
definitely reduce the energy wastage. Besides, using the energy efficient equipment
such as energy saver bulb can definitely lower the power consumption. As for cooling
system, the temperature surrounding is monitored by the temperature sensor and the
microcontroller will control the temperature of the air-conditioning system depends
on the room temperature at that time. In addition, the occupancy sensor will send
signal to the controller either to on or off depending on the present of people in the
particular room. A small feature is added into the system where the blind used is
automated using the photo sensor to control the amount of lights getting into the
room.
