A leading Government Hospital in Tamil Nadu, one of India’s oldest government-run medical institutions, for that Conserve Consultants conduct a comprehensive Sustainability & Energy Audit to identify opportunities for energy cost reduction, system optimization, and lowering carbon emissions.
The audit evaluated major systems including HVAC, chilled water network, solar energy potential, lighting, water management, and indoor air quality. The study was carried out through detailed measurement, logging, and performance analysis.
Key findings and opportunities include Sustainability & Energy Audit:
HVAC System Modernization
The central chiller plant was observed to be operating at lower efficiency, which can significantly impact both energy consumption and operational costs. The HVAC system upgradation has improved the energy performance of the facility's cooling system. By optimizing system efficiency, energy consumption was dramatically reduced cutting the power usage per ton of cooling by over 60%. This modernization not only enhances operational performance but also supports sustainability goals through reduced environmental impact.
Estimated Benefit: ₹30 Lakhs annual cost savings with a substantial reduction in electricity usage.
On-Site Renewable Energy
As part of the commitment to cleaner energy and long-term cost savings, a comprehensive assessment was conducted to utilize available rooftop space for renewable energy generation. The analysis confirmed strong potential for solar power integration, enabling a substantial portion of the facility’s electricity needs to be met through on-site generation.
By reducing reliance on grid electricity, this initiative enhances energy resilience, lowers carbon emissions, and positions the facility as a forward-thinking leader in environmental stewardship. The move towards rooftop solar is a strategic step in achieving greater energy independence while supporting broader sustainability goals.
Estimated Benefit: ₹275 Lakhs annual cost savings with a reduction in 2749.4 CO₂ emissions.
Resource Optimization
During energy assessment, key opportunities were identified to enhance operational efficiency across the facility. By implementing intelligent control strategies, optimizing the use of natural daylight, and improving ventilation systems, the facility can achieve better energy performance while enhancing occupant comfort.
These targeted improvements not only reduce energy consumption but also support a healthier and more productive indoor environment. From refined thermal comfort to smarter system operations, the initiative underscores a commitment to sustainability, efficiency, and innovation in building performance.
Estimated Benefit: ₹104 Lakhs annual cost savings through reduced energy wastage and improved operational performance.
Sustainability & Energy Audit Transforming Energy Efficiency in Healthcare
The sustainability assessment covered high-impact opportunities in key areas such as energy efficiency, renewable energy adoption, and intelligent resource management. These enhancements are designed to significantly lower energy consumption, reduce operational losses, and increase the facility’s energy independence.
The projected benefits are substantial annual cost savings of ₹4.5 Crores and a reduction of over 4,300 tons of CO₂ emissions. These outcomes not only drive financial efficiency but also reinforce the hospital’s commitment to environmental responsibility, patient comfort, and leadership in sustainable healthcare.
