A formal document or label classifying an elevator's energy efficiency according to a standardised scale, typically based on VDI 4707 or ISO 25745 measurement methodology.
Full Definition
The elevator energy certificate is an efficiency classification document issued after measuring the elevator's energy consumption in standby, partial load, and full load operating conditions. The most widely used European framework is VDI 4707-1 / ISO 25745-2, which defines energy efficiency classes A (most efficient) through G (least efficient) based on annual energy demand per unit reference travel. The certificate assists building owners in comparing elevators, qualifying for green building certifications (LEED, BREEAM), and meeting energy performance regulation requirements. Regenerative-drive elevators, LED lighting, and efficient standby management typically achieve Class A or B ratings. The certificate must be based on actual measured data, not manufacturer claims alone, and must be renewed after major modernisation affecting energy-related components.
