Optimising Energy Efficiency in Lifts for Sustainable Building Management
The Australian property sector is increasingly focused on sustainability, with stringent ESG (Environmental, Social, and Governance) reporting requirements and net-zero targets driving decisions across new builds and existing assets. This trend places significant emphasis on a building's operational carbon footprint, and vertical transport systems are a key component of this calculation. As major energy consumers within commercial and residential buildings, the efficiency of lift systems directly impacts a property's overall sustainability performance and attractiveness to investors and tenants. For building consultants and developers, understanding and integrating energy-efficient lift solutions is no longer a niche consideration but a fundamental aspect of future-proofing assets and achieving compliance. We are observing a noticeable shift towards specifying systems that not only meet performance criteria but also deliver demonstrable environmental benefits, aligning with broader industry movements towards a more sustainable built environment.
Industry Notes
Energy efficiency in vertical transport refers to the implementation of technologies and strategies designed to minimise the power consumption of lift systems. Key technologies contributing to this include regenerative drives, which capture energy generated when the lift car descends or travels with a light load and feed it back into the building's electrical grid. Modern lift systems also incorporate LED lighting in car interiors and machine rooms, significantly reducing power usage and heat generation compared to traditional lighting. Standby or "sleep" modes are another common feature, powering down non-essential components during periods of inactivity. Destination control systems improve efficiency by grouping passengers travelling to similar floors, reducing the number of stops and overall travel time. Furthermore, the transition from geared to gearless permanent magnet synchronous motors (PMSM) offers superior energy efficiency due to less friction and heat loss. These integrated approaches are critical for lowering operational costs and enhancing a building's green credentials.
Tips of the Week
1. Conduct an energy audit of your existing lift portfolio to identify specific areas of high consumption and potential for upgrades.
2. When planning new installations or modernisations, prioritise lift specifications that include regenerative drive systems and smart controls.
3. Implement a proactive maintenance schedule that specifically addresses the calibration and optimal function of energy-saving features within your lift systems.
4. Consider upgrading to LED lighting within lift cars, lobbies, and machine rooms for immediate energy savings and reduced heat load.
5. Explore the feasibility of incorporating destination control systems in high-traffic buildings to optimise passenger flow and reduce energy-intensive stops.
Closing Remarks
The ongoing emphasis on building sustainability underscores the critical role of energy-efficient vertical transport solutions in meeting modern property demands.
