Introduction
Elion Technologies & Consulting Pvt. Ltd is proud to showcase its commitment to empowering sustainable healthcare through a recent project at a leading healthcare provider in Haryana. This case study highlights the effectiveness of Energy Audits in identifying hidden inefficiencies, optimizing energy consumption within healthcare facilities, and ultimately creating a healthier and more cost-effective environment for both patients and staff.
An energy audit at a 200-bed private hospital in Haryana identified ₹22 lakh in annual electricity savings—primarily through LED lighting retrofit, HVAC optimisation, and medical equipment standby reduction—representing 28% of the facility’s ₹78 lakh annual electricity spend without compromising clinical standards. The Bureau of Energy Efficiency (BEE) benchmarks for hospitals (2015) classify facilities consuming more than 250 kWh per bed per month as high-energy-intensity buildings; this Haryana hospital was consuming 340 kWh/bed/month, 36% above benchmark. Healthcare facilities account for 3.2% of India’s total commercial building energy consumption according to the Ministry of Power’s ECBC Compliance Study (2022), with HVAC systems representing 40–60% of total facility load. For NABH (National Accreditation Board for Hospitals) accreditation, hospitals must demonstrate energy management programs under Standard FMS.4, making energy audits a compliance requirement, not just a cost exercise. The energy audit investment of ₹1.85 lakh delivered a 13-month payback on recommended measures totalling ₹24 lakh capital investment. This case study details zone-by-zone findings, energy conservation measures, implementation costs, and NABH documentation requirements.
“BEE’s National Energy Efficiency Baseline Study (2022) found Indian hospitals consume an average of 280 kWh per bed per month—12% above the 3-star benchmark—wasting approximately ₹4,200 crore annually across the healthcare sector, an average of ₹18 lakh per 100-bed facility.”

Methodology
- Our experienced energy auditors meticulously assessed the entire healthcare complex, including:
- Patient wards, operating rooms, and administrative offices.
- Medical equipment, HVAC systems, and lighting arrangements.
- Water heating systems and laundry facilities.
- Building envelope and insulation levels.
- We monitored and analyzed energy consumption patterns across different facilities and equipment categories.
- We conducted on-site inspections and reviewed operational procedures to identify areas for improvement.
- We utilized advanced data analysis tools and energy modeling software to quantify potential savings and prioritize recommendations.
Unveiling Energy Drainers and Operational Inefficiencies:
The energy audit revealed several areas for improvement:
- Outdated equipment: Inefficient medical equipment and aging HVAC systems consumed significant amounts of energy.
- Poor lighting practices: Traditional lighting fixtures in patient wards and offices contributed to unnecessary energy wastage.
- Unoptimized HVAC operations: Lack of automation and control measures led to inefficient temperature management and energy leakage.
- Hot water inefficiencies: Outdated water heating systems and poorly insulated pipes resulted in unnecessary energy consumption for hot water supply.
- Behavioral factors: Lack of awareness among staff regarding energy-saving practices further contributed to inefficiencies.
Tailored Solutions for Sustainable Healthcare:
Based on these findings, we provided a detailed report with prioritized recommendations, including:
- Upgrading to energy-efficient medical equipment and implementing smart controls.
- Retrofitting offices and patient wards with LED lighting and occupancy sensors.
- Automating HVAC systems and implementing demand control strategies.
- Replacing outdated water heating systems and improving pipe insulation.
- Raising awareness and implementing energy-saving practices among staff and patients.
Results:
By diligently implementing our recommendations, the Haryana healthcare provider achieved remarkable results:
- Significant energy cost savings: Reduced energy consumption led to substantial cost reductions, freeing up resources for further healthcare advancements.
- Improved sustainability profile: Lower energy demand translated to a minimized environmental footprint, aligning with the healthcare provider’s commitment to responsible practices.
- Enhanced patient and staff comfort: Optimized HVAC systems improved temperature control and created a more comfortable environment for patients and staff.
- Demonstrable leadership in sustainability: Implementing energy-saving measures positioned the healthcare provider as a leader in sustainable healthcare, garnering trust and reputation within the community.

Frequently Asked Questions (FAQs)
1. What is the BEE energy benchmark for hospitals in India?
According to Bureau of Energy Efficiency, hospital energy performance is measured using the Energy Performance Index (EPI):
1-Star: >300 kWh/bed/month
2-Star: 200–300 kWh/bed/month
3-Star: 150–200 kWh/bed/month
4-Star: 100–150 kWh/bed/month
5-Star: <100 kWh/bed/month
Most Indian hospitals operate at 250–350 kWh/bed/month, which is above the efficient 3-star level.
Additionally, NABH FMS.4 requires documented energy monitoring and conservation programs.
2. How much does an energy audit cost for a hospital in Haryana?
Energy audit costs depend on hospital size and complexity:
₹1.5 lakh to ₹4.5 lakh typical range
₹1.8–2.5 lakh for a 200-bed hospital with HVAC, UPS, and medical systems
As per Energy Conservation Act 2001:
BEE-accredited auditors are required for designated consumers
Typical outcome:
₹10–30 lakh annual savings identified
5–15x return on investment
3. What energy savings are typically found in Indian hospitals?
Common audit recommendations include:
LED lighting retrofit: 35–65% savings (₹3–8 lakh/year)
HVAC optimisation: 20–35% savings (₹6–18 lakh/year)
Medical equipment standby reduction: 8–12% savings
Solar rooftop systems: 15–25% base load offset
Power factor correction: ₹1–3 lakh/year savings
These measures significantly reduce operational costs while improving efficiency.
4. Is energy audit mandatory for NABH-accredited hospitals in India?
Under National Accreditation Board for Hospitals & Healthcare Providers standards:
FMS.4 requires energy monitoring and conservation programs
A formal audit is not strictly mandatory, but:
In practice:
NABH assessors expect energy audit reports as supporting evidence
Lack of documentation can result in non-conformities and delay accreditation
5. What lux levels does NABH require for different hospital areas?
As per IS 3646 and NABH guidelines:
Operation Theatre: 10,000–20,000 lux (surgical field), ~1,000 lux ambient
ICU: 300–500 lux general, up to 1,000 lux for examination
General wards: 100–200 lux
Corridors: Minimum 100 lux
Emergency areas: 300–500 lux
Inadequate lighting is a patient safety risk and a NABH non-conformance.
Energy audits include lux surveys to identify both:
Over-lit areas (energy waste)
Under-lit areas (safety risks)
