Modern hospitals require a substantial amount of energy to operate, with electricity being crucial for everything from life-saving medical equipment to maintaining a sterile environment. Particularly in hot regions like Saudi Arabia (KSA) and the UAE, energy demand surges due to the high reliance on HVAC systems. Managing energy efficiently not only supports hospital sustainability goals but also reduces operational costs—an imperative for healthcare facilities worldwide. By understanding the key factors driving daily electricity consumption in hospitals, stakeholders can make informed decisions to balance costs and sustainability.
How Much Electricity Does a Hospital Use Per Day?
A typical hospital consumes a significant amount of electricity daily, with large facilities requiring upwards of 50,000 kWh per day in some cases. For example, studies have shown that hospitals in the United States use approximately 27.5 kWh per square foot per year, while facilities in the Gulf region, facing more extreme temperatures, often report higher values.

Understanding Hospital Energy Consumption
Hospitals are among the most energy-intensive facilities due to their 24/7 operation and the need for continuous heating, cooling, lighting, and medical equipment. The average daily electricity consumption varies based on factors like facility size and equipment, but the following breakdown provides insights into how hospitals typically allocate their energy:
- Small Hospitals: Around 5,000–15,000 kWh per day
- Medium-Sized Hospitals: 15,000–30,000 kWh per day
- Large Hospitals: 30,000–50,000+ kWh per day
These levels underscore why hospitals require targeted strategies for efficient energy management, especially when compared to other commercial buildings.
13 Key Factors Affecting Hospital Electricity Usage Per Day
1. Climate and Location
In regions like KSA and the UAE, where temperatures often exceed 40°C, HVAC systems work intensively, resulting in high electricity consumption. Cooling and ventilation are essential for patient comfort and infection control, with demand peaking during summer. Regional electricity costs and grid reliability also influence hospital energy budgets, making location a significant factor.
2. Size of the Facility
The size and structure of a hospital directly affect its energy use. Larger hospitals or specialty centers consume significantly more energy than smaller facilities due to extensive HVAC, lighting, and equipment demands. Smaller clinics may have lower energy requirements but still need efficient systems to manage energy.
3. Heating, Ventilation, and Air Conditioning (HVAC) Systems
HVAC systems maintain air quality, regulate temperature, and control humidity levels, critical in healthcare settings. Advanced AC monitoring and control systems, like those provided by AEMACO, help hospitals optimize HVAC usage by using real-time data to adjust settings based on occupancy and environmental conditions, reducing waste and improving efficiency.
4. Lighting Needs
Hospitals operate round-the-clock, requiring constant lighting in critical areas such as ERs and ICUs. While traditional lighting contributes to high electricity bills, energy-efficient LED lighting and smart scheduling significantly reduce consumption. Hospitals using automated lighting control systems report reductions in energy usage without compromising visibility or patient safety.
5. Medical Equipment Usage
High-energy medical devices like MRIs, CT scanners, and X-rays are crucial but consume substantial electricity. Efficient scheduling of imaging equipment and investing in energy-efficient technology can mitigate these costs. Additionally, periodic equipment maintenance ensures devices operate efficiently, minimizing unnecessary energy drain.
6. Water Heating and Sterilization
Hot water is indispensable for sterilizing medical instruments, especially in surgical and laboratory settings. Energy-efficient sterilization methods, like low-temperature sterilizers, can substantially lower the hospital’s overall energy use while meeting hygiene standards critical to patient care.
7. Building Design and Age
Older hospitals often have outdated infrastructure, resulting in inefficient energy use compared to newer, energy-efficient buildings. Retrofitting insulation, upgrading windows, and installing energy-efficient HVAC systems in older facilities can reduce electricity usage, making energy conservation measures highly impactful.
8. Automation and Energy Monitoring Systems
Automation allows for real-time monitoring and optimization of energy use across hospital facilities. Systems such as AEMACO’s energy monitoring solutions provide actionable insights, enabling staff to adjust energy use based on demand. This reduces energy waste and aligns consumption with operational needs.
9. Operating Hours and Patient Occupancy Rates
High patient occupancy generally increases energy requirements for lighting, ventilation, and medical services. Monitoring occupancy and adjusting systems accordingly can reduce unnecessary energy use during low-occupancy hours, promoting a balanced approach to energy management.
10. On-Site Pharmacies and Laboratories
Pharmacies and laboratories are energy-intensive due to their use of refrigeration, ventilation, and equipment like centrifuges. Designing these spaces efficiently, using energy-saving equipment, and implementing proper scheduling can help mitigate their high energy requirements.
11. Staff and Patient Behaviors
Hospital staff and patients play a critical role in energy efficiency. Simple behaviors—like turning off unused lights and maintaining recommended thermostat settings—significantly impact energy use. Hospitals that conduct energy-saving awareness programs often report measurable reductions in their daily electricity consumption.
12. Energy Efficiency Policies and Certifications
Green certifications such as LEED (Leadership in Energy and Environmental Design) encourage hospitals to adopt sustainable practices. Compliance with energy efficiency policies often includes implementing high-efficiency lighting, HVAC systems, and water heating solutions, directly impacting electricity use.
13. Energy Supply and Backup Systems
In regions prone to power disruptions, backup systems are essential. Hospitals often rely on diesel or natural gas generators, which add to electricity costs. Investing in sustainable alternatives like solar backup or battery storage systems can provide clean, reliable energy, particularly beneficial for hospitals in high-temperature regions like KSA and UAE.

Sustainability and Environmental Impact of Hospital Energy Use
With rising awareness of environmental concerns, the need to reduce the carbon footprint of healthcare facilities has become more pressing. Hospitals are large consumers of electricity, and this intensive use contributes to higher emissions, especially when energy comes from non-renewable sources. In regions like KSA and the UAE, where reliance on fossil fuels is high, each hospital’s energy footprint significantly impacts the environment. By adopting sustainable practices, hospitals can help reduce greenhouse gas emissions while still meeting the needs of patients and staff. Simple measures, such as utilizing solar energy for backup power, optimizing HVAC systems, and investing in energy-efficient building designs, can go a long way in curbing environmental impact. Implementing sustainable energy practices can enhance a hospital’s public image, potentially attracting more environmentally conscious patients, staff, and stakeholders, while setting a precedent for sustainability within the healthcare sector.
The Financial Benefits of Energy Efficiency in Hospitals
Energy-efficient practices not only benefit the environment but also offer substantial financial savings. Hospitals in KSA and the UAE that incorporate real-time energy monitoring and automated controls can see reductions in operational costs by up to 15–20%. For instance, optimizing HVAC and lighting systems can drastically cut electricity bills, translating to more funds available for other crucial areas like patient care or advanced technology. Additionally, many regions offer financial incentives, rebates, or tax benefits for healthcare facilities that meet specific energy efficiency standards or adopt renewable energy sources. These savings, coupled with lower operational costs, make energy efficiency a strategic financial decision for hospitals. With partners like PROVEN Consult and solutions like AEMACO’s advanced monitoring systems, hospitals can achieve these savings effectively, ensuring their resources are used where they matter most—improving patient outcomes and facility operations.
