Energy Review and Audit Framework

An-Najah National University (ANNU) has institutionalized a comprehensive and recurring Energy Review Program designed to systematically identify and address areas of highest energy wastage across all campuses. These reviews form a cornerstone of the University’s Energy Efficiency and Climate Action Strategy, aligning with national energy goals and the UN SDG 7 targets for affordable and clean energy.

Energy and Climate Change Research UnitThe energy review is conducted annually by the Energy and Climate Change Research Unit, in cooperation with the Engineering and Maintenance Department and Faculty of Engineering and IT, ensuring a data-driven, multidisciplinary, and evidence-based approach to energy performance improvement.

1. Objectives of the Energy Review

• Identify Critical Energy Loss Points: Evaluate all buildings and utilities to locate energy-intensive systems, operational inefficiencies, and uncontrolled energy losses.

• Establish Performance Benchmarks: Compare energy consumption patterns against international standards (ASHRAE, ISO 50001) to guide corrective action.

• Support Net-Zero Targets: Directly contribute to the University’s Net-Zero Carbon Target 2028, ensuring continuous reductions in Scope 1 and 2 emissions.

• Promote Community Benefit: Reallocate surplus renewable energy produced on campus to nearby rural areas lacking electricity access, advancing social sustainability alongside energy efficiency.

2. Methodology and Review Process

The University’s Energy Audit Framework combines quantitative measurements with qualitative assessments through:

• Smart Meter Data Analysis: Continuous monitoring of building-level electricity use via IoT-enabled meters integrated into the Najah²Twin Smart Campus System.

• Thermal Imaging Surveys: Identification of heat-loss zones and insulation deficiencies in major facilities using infrared thermography.

• Appliance and HVAC Efficiency Testing: Field measurements of laboratory, office, and classroom appliances to assess energy draw and standby losses.

• Load Profiling: Hourly analysis of consumption patterns to detect non-essential nighttime or idle-hour energy usage.

• Benchmarking by Function: Energy intensity (kWh/m² and kWh/person) compared across faculties (Science, Medicine, Engineering, Agriculture, etc.) to prioritize retrofit actions.

3. Key Findings and Implemented Actions (2024–2025)

• Electricity Generation: 100% of campus electricity in 2024 was supplied from on-site renewable sources, totaling 1,572,222 kWh, with an additional 3,320,168 kWh generated and partially exported to underserved rural communities.

• Consumption Reduction: Building-specific audits led to a 12% reduction in total energy use through retrofits in lighting, HVAC optimization, and smart scheduling.

• Behavioral Interventions: Awareness campaigns and “Switch-Off” programs reduced after-hours consumption by 8% in administrative buildings.

• Expanded Renewable Infrastructure: Installation of solar carports, hybrid PV systems at the hospital, and biogas production units further offset non-renewable energy demand.

4. Future Directions (2025–2028)

• Comprehensive ISO 50001 Energy Management Certification across all campuses.

• Integration of AI-Based Predictive Analytics in the Najah²Twin digital twin platform for real-time anomaly detection.

• Expansion of Smart Metering Network to student dormitories and the University Hospital.

• Launch of Green Building Retrofits Phase II targeting 30% further reduction in energy intensity by 2028.

Conclusion

Through systematic, data-driven energy reviews, An-Najah National University not only identifies where energy wastage is highest but also implements measurable, science-based corrective actions. These ongoing audits exemplify the University’s leadership in sustainable campus management, demonstrating tangible progress toward energy efficiency, community empowerment, and net-zero transformation.
