Elevator Energy Efficiency Assessment

Greener Vertical Transportation

Although lifts and elevators only account for 3% to 8% (4% in the EU) of a building’s total power consumption, they have strong potential for energy savings and efficiency because of their long lifetime. For many property developers, boosting elevator efficiency helps reduce carbon emissions and the impact of modern architecture on the environment. TÜV Rheinland’s experts can help you identify your product’s energy efficiency according to VDI 4707 Part 1. We can help you improve energy efficiency together with architects, elevator manufacturers, and building owners.
