Elevator Energy Efficiency & Classification from Schindler Lifts

Attributed with a relatively extended life span of 25 to 30 years, the key to reducing the environmental impact of an elevator lies clearly in its operational phase. Therefore, Schindler's policy is that all new products have a better eco-performance than their predecessor models. Owing to intelligent and ecofriendly design, Schindler elevators ensure the highest possible performance and efficiency, thus generating substantial contribution to minimizing a buildings ecological footprint across their life cycle.

Schindler assesses its elevators based on the VDI 4707 standard, an elevator energy efficiency classification guideline established by the association of German Engineers. The VDI 4707 is widely applied in Europe and quickly gaining popularity in other parts of the world.

• VDI 4707 measures and classifies elevators according to their energy efficiency.
• It defines an Energy label and gives a figure for an "yearly nominal energy demand"
• Elevators are rated from "A" to "G" according to their energy performance, with "A" being the most efficient, best-in class system.
• The rating combines measurements of both standby and travel energy. Ratings are also influenced by travel height, speed, load and usage frequency

All Schindler VDI assessments are based on actual operational on-site measurements. Schindler believes this to be the only factual guide to an elevators energy efficiency, which gives an accurate operational rating as opposed to a lab tested result.

The measurements and classification are a guideline for Schindler to further contribute to sustainable building development.
