Crescent Sustainability Initiatives
Affordable and Clean Energy (SDG 7)
Foundational Insights from the Energy Audit
The energy audit conducted at B.S. Abdur Rahman Crescent Institute of Science and Technology has laid a robust foundation for an energy efficiency plan aimed at significantly reducing overall energy consumption on campus. The audit identified key areas where energy savings can be achieved, amounting to an annual savings potential of 487,014 kWh, which translates to a cost saving of approximately Rs. 40,11,685/- (Rupees Forty Lakh Eleven Thousand Six Hundred and Eighty-Five only). The proposed investment for implementing various energy conservation measures (ECMs) is estimated at Rs. 1,59,50,000/- (Rupees One Crore Fifty Nine Lakh Fifty Thousand only), with an average payback period of 48 months. This structured approach not only emphasizes immediate cost savings but also aligns with the institution’s commitment to sustainability and renewable energy.
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.
Enhancing Energy Management Through Monitoring
Additionally, the audit highlights the importance of monitoring and controlling energy usage through the installation of dedicated energy meters and a demand controller. These systems will provide real-time data on energy consumption, enabling the management to make informed decisions about energy usage patterns and identify further opportunities for savings. By actively managing demand and optimizing energy consumption, the institute can avoid penalties associated with exceeding contract demand, thereby enhancing overall financial efficiency.
Towards a Sustainable Future: A Commitment to Energy Efficiency
In conclusion, the energy efficiency plan at Crescent Institute is a comprehensive strategy that not only aims to reduce energy consumption but also fosters a culture of sustainability within the campus community. By implementing these measures, the institute is poised to make significant strides toward achieving its renewable energy goals while setting a benchmark for energy efficiency in educational institutions across the region. The commitment to continuous improvement and innovation in energy management will ultimately contribute to a greener and more sustainable future for the institute and its stakeholders.
