Optimise Building Performance: Focus on Lift Energy Efficiency & Lifecycle Costs
Across Australia, the building sector is experiencing an accelerated drive towards greater sustainability and energy efficiency, largely influenced by rising energy costs, updated NABERS rating requirements, and evolving tenant and investor expectations for green buildings. Vertical transport systems, often overlooked, are significant energy consumers within a building's operational footprint. This heightened focus on environmental performance means that builders and consultants are now scrutinising every aspect of building design and operation. Specifying energy-efficient lift systems in new builds, or planning for energy-saving modernisations in existing properties, is no longer a niche consideration but a mainstream imperative. Failing to integrate efficient vertical transport solutions can lead to higher operational expenses, potentially impacting property valuations, and making it harder to meet increasingly stringent sustainability benchmarks. Understanding these broader market dynamics is crucial for making informed decisions that contribute positively to a building's overall lifecycle performance and market appeal.
Industry Notes
Energy efficiency in vertical transport is a critical design and operational consideration. Several technologies and strategies contribute to reducing a lift system's power consumption. Modern lift systems commonly incorporate regenerative drives, which capture energy generated when the lift descends with a heavy load or ascends with a light load, feeding it back into the building’s electrical grid rather than dissipating it as heat. Machine Room-Less (MRL) designs often utilise gearless permanent magnet synchronous motors, which are inherently more efficient than traditional geared motors. Other energy-saving features include LED cabin lighting with motion sensors, intelligent standby modes that reduce power consumption during periods of inactivity, and advanced destination control systems that optimise car dispatching and reduce unnecessary travel. Proper maintenance also plays a vital role; well-lubricated and correctly adjusted components operate more efficiently, preventing energy wastage from increased friction or motor strain. Implementing these measures can significantly lower a building's operational costs and improve its environmental profile.
Tips of the Week
1. For new projects or major modernisations, specify regenerative drives and high-efficiency permanent magnet synchronous motors to maximise energy recovery and minimise consumption.
2. Ensure lift specifications include LED lighting with motion sensors and programmable standby modes to reduce power draw during off-peak hours.
3. Incorporate energy monitoring into your building management system (BMS) for vertical transport, allowing you to track consumption and identify potential inefficiencies.
4. Engage with your lift service provider to review existing lift systems for potential energy-saving upgrades, such as drive modernisations or lighting retrofits.
Closing Remarks
The increasing emphasis on sustainability and energy efficiency within the built environment places vertical transport systems firmly in the spotlight for lifecycle performance and cost management. By understanding the latest industry developments and implementing practical, energy-saving strategies, building professionals can significantly enhance their property’s operational efficiency and environmental credentials. We are committed to providing informed insights and are available to discuss how these considerations can be best applied to your specific projects and property portfolio.
