Authorized Timer for Reduction of Electricity Consumption and Energy saving in Classrooms

摘要

In recent years, reduction of energy consumption and energy savings are highly important and demanding issues in either residential or commercial applications. Many research studies focus in this field and among others, re-retrofitting energy efficient lighting fixtures and using energy STAR appliances (such as energy efficient air conditioning (AC) units) are some of the suggested solutions for reducing electrical energy consumption. The work in this paper proposes the use of specially designed electronic timers for further reduction of electrical energy consumption and consequently save energy. The timers are integrated with efficient Light Emitting Diode (LED) lamps and air conditioning units in order to achieve minimal energy consumption. Only authorized persons are able to access and configure the timers so as to manage the working hours of the classroom electrical load units such as lighting, air conditioning, and other appliances. The analysis of the collected data reflects the effectiveness of the proposed system in electrical energy consumption reduction and energy saving.
