Case Study:
Unnecessary Electricity Consumption in
AL-Mustaqbal University Buildings
2
1. Introduction: Many educational institutions suffer from unnecessary
electricity consumption, leading to increased operational costs and reduced
energy efficiency. This study aims to analyze electricity consumption in
some university buildings by highlighting the number of lights operating
without benefit and the amount of current consumed.
2. Data Analysis: Lighting consumption was observed in the following
buildings:
• Engineering Building:
o Number of indoor lights operating without benefit: 87
o Number of outdoor lights operating without benefit: 10
o Number of external ballasts operating without benefit: 4
o Total number of lights operating without benefit: 101
o Total current consumed for lighting: 25.25A
• Medical Building 1:
o Number of lights on the ground floor operating without
benefit: 54
3
o Number of lights on the first floor operating without benefit:
54
o Number of outdoor lights operating without benefit: 5
o Total number of lights operating without benefit: 113
o Total current consumed for lighting: 28.25A
4
• Other Areas (Humanities, Science College, Pharmacy, Graduate
Studies):
o These rely on the photosensor system (automatic light
shutoff), reducing unnecessary electricity consumption.
3. Potential Impacts:
• Increased operational costs: Unnecessary lighting increases the
institution's electricity bill.
• Negative environmental impact: Excessive electricity
consumption contributes to higher carbon emissions, negatively
affecting the environment.
5
• Reduced equipment lifespan: Continuous operation of lights
decreases their lifespan and increases maintenance and replacement
costs.
4. Proposed Solutions:
1. Install motion sensors and photosensors in all buildings to
automatically turn lights on and off when needed.
2. Raise awareness among students and staff about the importance
of energy conservation.
3. Upgrade the lighting system using energy-efficient LED bulbs.
4. Implement a manual light shutdown policy during unnecessary
periods through periodic monitoring.
5. Final Recommendations:
• Conduct regular electricity consumption audits in all university
buildings.
• Expand the use of the photosensor system to cover all buildings,
as implemented in other areas.
• Encourage the use of renewable energy systems, such as solar
panels, to reduce dependence on the conventional power grid.
• Activate an incentive program for staff and students to propose
innovative ideas and solutions for energy conservation.
6. Conclusion: Addressing the issue of unnecessary energy consumption
in educational institutions is a crucial step toward sustainability and
resource conservation. By implementing the proposed solutions, energy
consumption can be reduced, and the institution's operational efficiency
can be improved.
