Insights for Indian Building Owners
Understanding the electricity consumption of lifts is crucial for property owners and managers in India, where energy efficiency is increasingly becoming a priority. The annual electricity use of an elevator system is influenced by several factors, including the type of elevator, usage patterns, the height of the property, and the modernity of the elevator. According to benchmark data, an elevator’s electricity consumption can account for approximately 5% to 10% of a building’s total energy usage, depending on the variables listed above.
In February 2024 Bloomberg reported that due to a substantial 7% YoY increase in energy consumption in 2023, the Indian government has revised its predictions for the country’s annual energy consumption to 384 gigawatts by 2032. As a result, the cost of electricity and environmental concerns are becoming increasingly important considerations for property owners and building managers in India. Selecting the right elevator system and maintaining it properly can lead to significant savings and a reduced carbon footprint. This article delves into the energy consumption of various elevator types and provides insights into how building managers can optimize efficiency and reduce costs.
The energy consumption of an elevator can vary significantly based on its design and other factors. Read along to delve into different elevator types in terms of energy use:
Hydraulic Elevators: Higher Energy Costs
Hydraulic elevators were widely used over the past few decades in smaller buildings with fewer stories. They tend to be less energy-efficient than other types of elevators. A hydraulic lift in a three-story building, for instance, may consume up to 4,000 kWh of electricity per year. This varies based on factors such as use frequency and the modernity of the elevator, however, under the same operating conditions, the energy usage of a hydraulic system is typically higher than that of other lift types.
Traction Elevators: Leading the Way in Efficiency
Traction elevators are a highly energy-efficient solution. In a typical six-story building, a traction elevator might consume approximately 3,000 kWh annually, which is significantly lower compared to other elevator types (though actual energy consumption will vary based on frequency of use and other factors). This efficiency is due to the use of a counterweight system to move the elevator cabin up and down. In contrast, hydraulic elevators operate by pumping hydraulic fluid into cylinders to move the cabin, which reduces their energy efficiency.

Another critical factor influencing the energy consumption of a lift is proper elevator maintenance. While it might be tempting to cut costs by skimping on lift maintenance, this approach is shortsighted. Poorly maintained elevators not only consume more energy but also face a higher risk of breakdowns and costly repairs (Ensuring Lift Longevity: The Essentials of Regular Elevator Maintenance).
Here's why regular maintenance and timely elevator modernization are critical:
Maintenance Myths Debunked
The notion that delaying elevator maintenance saves money is a myth. While short-term expenses might be reduced, the long-term costs due to increased energy consumption and potential system failures can be substantial. Different types of elevators have varying maintenance requirements, but all benefit from regular service to ensure optimal performance and energy efficiency.

To navigate the complexities of lift maintenance and energy efficiency, here are actionable strategies for building owners and managers in India:
Regular Inspections: In addition to regular maintenance conducted by certified professionals, schedule annual or semi-annual inspections to identify and address potential issues before they escalate, thereby reducing repair costs.
Energy Audits: Conduct energy audits of your elevator systems to identify areas for improvement and determine when a comprehensive lift modernization might be beneficial.
Lift Modernization: Upgrading older elevators to newer, more energy-efficient models can provide long-term savings, enhanced safety, and improved performance.

Q: What is the average power consumption of a 4-passenger lift per month?
A: For a standard residential building in India, a 4-passenger lift power consumption per month typically ranges between 30 kWh to 60 kWh (units). This assumes average residential usage of about 50-80 trips per day. Modern lifts with Variable Voltage Variable Frequency (VVVF) drives and standby modes are at the lower end of this spectrum, while older geared models may consume more.
Q: How much electricity does a 6-passenger lift consume per month?
A: A 6-passenger lift power consumption per month is generally slightly higher, averaging between 45 kWh to 90 kWh (units). Since these lifts have larger motors and heavier counterweights to accommodate higher load capacities (typically 408 kg), they draw more power during operation. However, energy-efficient MRL (Machine Room-Less) traction lifts can significantly reduce this figure compared to hydraulic alternatives.
Q: Does a lift consume electricity when not in use?
A: Yes, lifts consume "standby power" to keep essential systems like the control panel, door sensors, and cabin lighting active. This can account for a surprising portion of your total lift electricity consumption. To minimize this, we recommend upgrading to LED cabin lighting and configuring the lift to enter "sleep mode" which turns off fans and lights after a period of inactivity.
Q: Which type of lift uses the least amount of electricity?
A: Traction elevators equipped with Regenerative Drives (Regen drives) are the most energy-efficient. They capture energy normally lost as heat during braking (when a heavy car goes down or a light car goes up) and feed it back into the building's electrical grid. In contrast, hydraulic lifts are generally less efficient and have higher lift power consumption because they require significant energy to pump fluid against gravity.
Key Takeaways
How much energy does an elevator typically consume?
On average, an elevator system accounts for approximately 5% to 10% of a building's total electricity usage, depending on the lift type, building height, and usage frequency.
Are traction lifts more energy-efficient than hydraulic lifts?
Yes, traction elevators are significantly more efficient because they utilize a counterweight system, whereas hydraulic lifts require more power to pump fluid for movement, leading to higher operating costs.
Does poor maintenance affect electricity bills?
Absolutely; neglected maintenance leads to friction and inefficiency, causing the system to draw more power and increasing the risk of costly breakdowns.
Why is energy efficiency critical for Indian building owners?
With India's electricity consumption and costs rising, upgrading to energy-efficient elevators helps property managers significantly reduce operational expenses and their carbon footprint.
