Abstract
The Global warming and other environmental issues have stimulated researchers to explore and implement methods to achieve energy savings. In this Research , a case study is presented to save energy in an educational building. Two methods are implemented: 1) Replacement of the compact fluorescent lamps by light-emitting longitudinal lamps (LEDs) ; 2) Smart energy control via the installation of motion, heat, sound and light sensors. The amount of energy savings is calculated in Egyptian pounds per annum. The amount of reduction in (CO2) emissions was also included. The luminous intensity is evaluated before and after replacement of the fluorescent lamps using the DIALux program. The practical installation of the proposed installation was conducted on a lecture’s hall and the dean’s office. A model of energy saving was simulated in Proteus with an Arduino platform , The model incorporated all the above sensors with different scenarios of operation , The model study revealed that an energy saving of 21.8% can be achieved. The total energy savings via the two methods was found 41.8 % and the payback period is about three years.
- The objective of this study is to present a model that has already been implemented in the governmental facilities of the Faculty of Industrial Education at Helwan University, the total connected load of the building as well as its energy consumption for one year are recorded and analyzed. The presented part of the study focused on saving energy via replacing the compact fluorescent lamps by longitudinal Light Emitting Diode (LED) lamps. Hence, the amount of energy savings in kilo Watt hours, in Egyptian Pounds, are calculated, per year. Also, the amount of reduction in Carbon Dioxide (CO2) emission is given. The luminous intensity is evaluated before and after the replacement via the DIALux software. Practical implantation of the proposed installation was carried out on a lecture hole and an office. Experimental measurements before and after the installation validated the amount of energy savings, it was also recommended to use energy-saving air-conditioning devices and mentioned its advantages and general idea. The smart system was designed with sensors to provide more power and operate the devices for less periods to maintain and to conserve energy simultaneously and to clarify the advantages and study of real costs of the project in order to solve the energy problem in Egypt as well as reduce annual expenses and also contribute to solving the environmental problem.
- Preparation of an educational unit built based on the results of the engineering segment in order to develop academic performance.
