Lifts are essential in many residential and commercial buildings, but older systems can consume more electricity than necessary. Ageing motors, outdated control systems, inefficient lighting, and frequent maintenance needs can increase the cost of keeping a lift operational.

Replacing an entire lift is not always the only option. Depending on the equipment’s condition, selected upgrades may improve energy efficiency, reliability, and day-to-day performance while allowing parts of the existing installation to remain in place.

For building owners and property managers, the important question is whether an upgrade can deliver meaningful savings over time. The answer depends on the lift’s age, usage, existing technology, building requirements, and the cost of modernisation.

Understanding the main upgrade options helps property owners make informed decisions about operating costs and future maintenance.

1. Understand Where Lift Energy Consumption Comes From

A lift uses electricity to move between floors, operate its doors, control its systems, and power lighting and other components. Energy consumption varies according to the lift’s design, motor technology, traffic levels, travel distance, and standby settings.

Older equipment may lack some of the energy-saving features found in newer systems. However, age alone does not determine efficiency. A well-maintained older lift may perform differently from a heavily used system with outdated controls.

Before planning an upgrade, building owners should understand how the lift currently uses energy.

Important factors include:

• Motor and drive technology: These components influence the electricity required for movement.
• Control systems: Lift controls determine how the system responds to calls and manages operation.
• Standby consumption: Lighting, displays, fans, and electronic components may continue using electricity when the lift is idle.
• Usage patterns: Busy buildings generally place different demands on lifts than buildings with occasional use.
• Maintenance condition: Poorly adjusted or deteriorating components may affect performance and reliability.

An energy assessment can help establish a baseline. This makes it easier to identify which upgrades are likely to offer the greatest benefit.

2. Upgrade Motors and Drive Systems

The motor and drive system are central to lift operation. Depending on the installation, upgrading these components may improve how efficiently the lift converts electrical energy into movement.

Modern drive technology can provide more precise control over motor speed and acceleration. This may also improve ride quality and reduce unnecessary operating stress when the system is correctly selected and configured.

However, the benefits depend on the existing equipment. Replacing a motor or drive solely because it is old may not deliver sufficient savings to justify the cost.

Before upgrading, consider:

• The existing motor’s condition and efficiency.
• The lift’s traffic volume and operating schedule.
• Compatibility with the controller and other components.
• Expected electricity savings under typical operating conditions.
• Installation costs and the required downtime.

A qualified lift contractor can assess whether a motor or drive upgrade is appropriate or whether another improvement would provide better value.

3. Install Regenerative Drive Technology Where Suitable

Some lift systems can recover part of the energy generated during certain movements. Regenerative drives capture electrical energy that would otherwise be dissipated as heat and can return it to the building’s electrical system for use by compatible loads.

The amount of energy recovered depends on factors such as lift design, loading, travel patterns, and the building’s electrical setup.

For example, certain combinations of lift direction and passenger load allow the lift motor to operate as a generator. A compatible regenerative drive can recover some of that energy rather than wasting it.

Potential considerations include:

• The type of existing lift drive.
• How frequently energy-generating movements occur.
• Compatibility with the building’s electrical system.
• Installation and integration costs.
• Expected annual energy recovery.

Regenerative technology is not equally beneficial for every lift. A usage assessment and realistic savings estimate should come before the investment decision.

4. Reduce Standby Energy Consumption

A lift does not use electricity only when travelling between floors. Some components continue operating while the lift is waiting for another call.

Depending on the system, standby consumption may come from lighting, displays, ventilation fans, and electronic controls. Upgrading these components can reduce unnecessary electricity use without requiring a complete lift replacement.

Common improvements include:

• Replacing older lift lighting with efficient LED lighting.
• Installing suitable automatic lighting controls.
• Using standby modes for compatible displays and auxiliary equipment.
• Reviewing fan operation and other non-essential loads.
• Configuring energy-saving settings according to the manufacturer’s requirements.

These improvements may be particularly useful in buildings where lifts remain idle for long periods.

Any standby changes must preserve required safety functions, emergency communications, accessibility, and other essential operations. Energy savings should never come at the expense of passenger safety or compliance.

5. Improve Lift Controls and Operating Efficiency

Lift control systems manage calls, movement, door operation, and other functions. Older controllers may lack the flexibility of modern systems, while newer controls can offer more precise operation and improved monitoring.

An appropriate controller upgrade may help the lift respond more effectively to passenger demand. Depending on the system, it may also support better coordination between multiple lifts.

However, improved traffic handling does not automatically guarantee lower electricity consumption. The result depends on the existing configuration, passenger patterns, and how the new system is programmed.

A control-system assessment should examine:

• How the lift responds to frequent calls.
• Whether door operation is appropriately adjusted.
• The performance of the current control equipment.
• Compatibility with motors, drives, and safety components.
• Opportunities for monitoring faults and operating patterns.

Better controls may also help technicians identify recurring issues. Early detection can support maintenance planning and reduce avoidable disruption, although the actual effect depends on the system and maintenance process.

6. Reduce Long-Term Maintenance and Repair Expenses

Energy efficiency is only one part of the financial case for lift modernisation. The condition of the equipment and its ongoing maintenance requirements also influence the total cost of ownership.

Older or obsolete components may become harder to source. This can increase repair times or make certain failures more expensive to resolve.

Modernisation can replace selected ageing components while retaining parts of the existing installation that remain suitable. This may help address specific reliability concerns without requiring a full replacement.

Potential benefits include:

• Improved availability of replacement components.
• Easier fault diagnosis with compatible modern controls.
• Reduced exposure to recurring faults caused by replaced components.
• More predictable maintenance planning.
• Better opportunities to monitor equipment performance.

These benefits are not guaranteed. A lift that already operates reliably may not experience a large reduction in maintenance costs after an upgrade. A professional assessment should identify the problems being addressed and estimate the likely financial impact.

7. Compare Modernisation Costs With Potential Savings

Lift upgrades involve upfront expenses, including equipment, engineering, installation, testing, and any required building work. The financial benefit depends on how much the upgrade reduces electricity use, maintenance expenses, or other operating costs.

A simple payback calculation can help compare options.

Simple payback period:

Payback period = Initial upgrade cost ÷ Estimated annual cost savings

For example, if an upgrade costs $12,000 and is expected to save $2,000 per year, the simple payback period would be six years. These figures are illustrative only and do not represent a typical lift upgrade cost or guaranteed savings.

A more complete assessment should also consider the lifespan of the upgraded components, future energy prices, financing costs, maintenance contracts, and possible downtime during installation.

Cost or benefit	What to assess
Initial investment	Equipment, labour, engineering, and installation
Electricity savings	Expected reduction based on actual lift usage
Maintenance expenses	Likely changes to servicing and repair costs
Downtime	Disruption during installation and commissioning
Component lifespan	Expected service life and replacement requirements
Compliance requirements	Any additional work needed to meet applicable standards

Ask contractors to explain the assumptions behind their savings estimates. Estimates based on actual usage and measured consumption are more useful than broad claims about percentage reductions.

8. Consider the Needs of Residential Buildings

Residential lifts serve a range of users, including families, older residents, visitors, and people with mobility needs. Modernisation decisions should therefore account for energy efficiency alongside accessibility, reliability, ride comfort, and safety.

In apartment buildings, lift usage may vary throughout the day. Morning and evening periods can bring higher demand, while other hours may involve long periods of inactivity.

A suitable upgrade should reflect these patterns rather than relying on a generic energy-saving package.

When assessing residential lifts Sydney, building owners and strata managers should consider the condition of the existing system, expected passenger demand, available space, and the needs of residents.

Useful questions include:

• Will the proposed upgrade improve the lift’s current performance issues?
• How long will the lift be unavailable during the work?
• Will residents have an alternative route or accessible option?
• Are the proposed components compatible with the existing installation?
• What testing and commissioning will take place before the lift returns to service?

Planning these details in advance can help building managers balance long-term improvements with the practical needs of residents.

9. Work With a Qualified Lift Modernisation Provider

Lift modernisation requires technical assessment, compatible components, appropriate installation, and thorough testing. Choosing an experienced provider helps building owners understand which upgrades are suitable for their equipment and what results are realistically achievable.

SkyRise Elevators provides a starting point for building owners researching lift services and upgrade options. Its lift modernisation services in Sydney can be reviewed when considering improvements to an existing installation.

Before approving a proposal, ask for a clear scope of work, estimated costs, expected downtime, testing arrangements, and an explanation of how the recommended upgrades address the building’s needs.

A useful proposal should distinguish between measured findings, projected savings, and benefits that depend on future usage. It should also identify any additional work required to maintain safety and meet applicable requirements.

Final Thoughts

Energy-efficient lift upgrades can help reduce operating costs when they address genuine inefficiencies in an existing system. Motor and drive improvements, regenerative technology, efficient lighting, standby controls, and modern controllers may all be worth considering, depending on the installation.

The strongest investment decisions begin with an assessment of current energy use, equipment condition, maintenance history, and passenger demand. Building owners can then compare the upfront cost with realistic estimates of electricity savings and other operating benefits.

Modernisation should not be judged by energy efficiency alone. Reliability, accessibility, safety, expected component lifespan, and disruption during installation also matter. With a clear assessment and a well-defined scope of work, property owners can choose upgrades that support the building’s long-term operating needs.
