Maximising Building Value: Addressing Energy Costs in Vertical Transport
The Australian commercial property sector is increasingly grappling with the dual pressures of rising energy costs and heightened expectations for sustainability performance. These factors are directly impacting the operational expenditure and attractiveness of buildings, placing vertical transport systems under scrutiny. As energy prices continue their upward trend, the often-overlooked energy consumption of lifts and escalators is becoming a more significant line item in a building's budget. Furthermore, with stricter NABERS ratings and corporate sustainability goals, building owners and managers are seeking every opportunity to reduce their carbon footprint. This shift means that decisions regarding lift installation, modernization, and maintenance are no longer just about reliability and safety, but critically about energy efficiency and long-term environmental impact. For building consultants and developers, understanding these dynamics is key to specifying systems that deliver optimal lifecycle costs and meet evolving market demands for green buildings. Proactive engagement with these trends ensures projects remain competitive and future-proofed.
Industry Notes
Energy efficiency in vertical transport systems is a critical focus for reducing operational costs and improving a building's environmental profile. Modern lift technology offers several pathways to achieve significant energy savings. One primary innovation is the implementation of regenerative drives, which capture the kinetic energy generated by the lift car when travelling lightly loaded upwards or heavily loaded downwards. Instead of dissipating this energy as heat, regenerative drives feed it back into the building's power grid, effectively turning the lift into a temporary electricity generator. Another key area is the use of gearless permanent magnet synchronous (PMS) motors, which are inherently more efficient than traditional geared motors due to reduced friction and enhanced power factor correction. Furthermore, intelligent control systems incorporate features like sleep modes during periods of low demand, automatic car lighting shutdown when empty, and destination dispatch systems that group passengers to reduce travel distances and stops. Upgrading to LED lighting within lift cars also contributes to substantial energy reductions compared to older halogen or fluorescent fixtures. Collectively, these technologies can lead to reductions of up to 70% in energy consumption compared to older, less efficient systems.
Tips of the Week
1. Conduct an energy audit of your existing vertical transport systems to identify consumption hotspots and potential upgrade opportunities. Many older systems are significant energy drains.
2. When specifying new lifts or modernisations, prioritise systems with regenerative drives and gearless PMS motors, as these offer the most substantial long-term energy savings.
3. Review lift traffic patterns within your building. Implementing smart scheduling or sleep modes during off-peak hours can reduce unnecessary operation and energy usage without impacting service levels.
4. Encourage regular, comprehensive maintenance. Well-maintained lifts run more efficiently, reducing wear and tear that can lead to increased energy consumption and premature component failure.
Closing Remarks
The ongoing focus on energy efficiency and sustainability in vertical transport systems is not merely a trend, but a fundamental shift impacting building value and operational viability.
