Universities are significant energy consumers, and improving energy efficiency is vital to achieving SDG 7 – Affordable and Clean Energy. The University of Al Maarif (UOA) has undertaken a comprehensive Energy Review and Audit to identify areas of high energy consumption, assess energy performance, and propose actionable improvements to enhance sustainability.

The audit focused on academic buildings, laboratories, residential dormitories, administrative offices, and recreational facilities. It evaluated electricity, heating, cooling, and water-related energy consumption, highlighting inefficiencies, high-consumption patterns, and potential for renewable energy integration.

Key findings include:

Academic and research buildings account for over 55% of total campus energy consumption.
Laboratories and IT centers consume disproportionately high energy due to equipment loads and continuous operation.
Residential dormitories and administrative offices show opportunities for lighting and HVAC optimization.
Lack of monitoring systems and energy awareness leads to energy wastage.

The report proposes targeted efficiency interventions, including:

Retrofitting lighting systems with LED and motion sensors.
Optimizing HVAC schedules and upgrading equipment.
Implementing renewable energy solutions such as solar PV and solar water heating.
Establishing an Energy Management Information System (EMIS) for continuous monitoring.
Promoting energy-saving behavior among staff and students.

The Energy Review and Audit report provides a roadmap for UOA to reduce energy consumption, lower carbon emissions, improve operational efficiency, and demonstrate leadership in sustainable higher education aligned with SDG 7.
