A.BSACIST Energy Management: External Audit-Driven Self-Assessment and Roadmap for a Resilient, Energy-Efficient Campus
B.S. Abdur Rahman Crescent Institute of Science and Technology, adopts a proactive, self-analytic approach to energy management, enhanced by an external Energy Audit. The institute commissioned an independent assessment to validate its energy landscape while preserving data ownership. The audit evaluated key systems—lighting, HVAC, motors, pumping, DG sets, and rooftop solar—along with utility bills and transformer loading, establishing a credible baseline and prioritized savings opportunities.
This external review catalyzes BSACIST’s ongoing energy performance improvements. It translates usage and peak-demand patterns into quantified ECMs with clear savings and payback, enabling phased investment and informed decision-making. By integrating the auditor’s findings with internal data and operations, BSACIST can verify savings, monitor progress with dedicated meters, and align initiatives with sustainability goals, including renewable energy integration and carbon reduction. This collaboration underscores the university’s leadership in responsible energy management and a path toward a more resilient, energy-efficient campus.
Actionable Measures for Energy Conservation
The energy efficiency plan encompasses a range of actionable measures, including the replacement of Fluorescent Tube Lamps (FTL) with energy-efficient LED lamps, which alone can save 19,200 kWh annually. Other significant initiatives include rectifying solar water heaters in the ladies’ hostel, upgrading existing air conditioning units to 5-star rated split ACs, and replacing conventional ceiling fans with energy-efficient Brushless DC electric motor fans. Each of these measures has been meticulously calculated to ensure substantial reductions in energy consumption while maintaining comfort and operational efficiency across the campus facilities.
