demands. With the global movement toward sustainability, HEIs have emerged as pioneers for implementing green energy practices and promoting energy awareness among students and staff (Rathod & Gohil, 2022).
Energy conservation in Higher Education Institutions (HEIs) is crucial not only for reducing operational costs but also for promoting sustainability and environmental responsibility. This study presents a comprehensive energy audit conducted at a HEI to assess its energy consumption patterns, identify inefficiencies, and propose corrective measures. The audit encompassed key components including electrical load analysis, lighting system evaluation, and power quality assessment. Data collection was carried out through a combination of electricity bill analysis, onsite equipment inspections, and phase-wise current measurements. Results revealed a total connected load of 48.93 kW, with air conditioners contributing the highest share (64%). The lighting inventory comprised mainly tube lights and CFLs, indicating substantial potential for energy savings through retrofitting with LED lighting. Phase-wise current analysis showed significant imbalance, suggesting the need for load redistribution. The study highlights actionable recommendations such as phased LED replacement, balanced phase loading, scheduled AC usage, and the integration of smart monitoring systems. Implementing these measures is expected to yield up to 20% reduction in energy consumption and align the institution with sustainable development goals. This case study demonstrates how targeted energy audits can serve as a foundation for long-term energy efficiency in academic campuses.
The role of HEIs in energy conservation is dual-pronged— they not only consume energy but also act as incubators of innovation and behavior change. HEIs are uniquely positioned to drive energy transformation through a combination of infrastructural modifications, technological adoption, and curriculum integration. Establishing smart energy policies, incorporating renewable sources like solar PV, deploying Internet of Things (IoT)-based monitoring systems, and encouraging sustainable behavior among stakeholders are key strategies being adopted globally (Sharma & Gupta, 2022). This paper presents an energy audit conducted at a HEI with the aim of assessing its current energy usage and recommending actionable strategies for energy efficiency. The study further discusses practical solutions aligned with cost-effectiveness, long-term sustainability, and compliance with national and global energy efficiency goals.
2. METHODOLOGY 2.1. Data Collection Energy consumption data were collected from the institution's electricity bills over a oneyear period. Additionally, onsite inspections were conducted to record the types and numbers of electrical equipment, lighting systems, and power quality.
Key Words: Energy Audit, Load Analysis, Sustainable Campus, LED Retrofitting
2.2. Load Analysis The total connected load was calculated based on the rated power and number of devices used across departments. Particular focus was given to high-energy-consuming devices such as air conditioners, computers, fans, and lighting.
1. INTRODUCTION Energy consumption in Higher Education Institutions (HEIs) plays a significant role in determining the operational efficiency and environmental impact of educational infrastructure. HEIs consist of multiple energy-intensive facilities including lecture halls, laboratories, libraries, computer centers, and hostels. These institutions function almost year-round and host a
