Reference Case: Energy Efficiency Testing and Certification of Elevators - China

Efficient use of energy is an increasingly significant factor in sustainable building operation. Rising energy costs and the growing public demand for eco-friendly solutions and greener buildings have led to comprehensive energy concepts for building equipment operation and modernization as well as stricter requirements in international certification standards.

Lift and component manufacturers are facing the challenge of providing energy efficient products . Schindler Group, a leading provider of elevators, escalators and related services, is committed to state-of-the-art transportation technologies and innovative, environmentally-friendly solutions. To get a clear, detailed and reliable overview of its elevator energy efficiency value in daily use, the company required a comprehensive energy audit of its products in five cities in China.

As an internationally respected Certification Body, TÜV Rheinland was entrusted with this project requiring them to conduct elevator energy efficiency measurements according to VDI 4707-1. The VDI 4707 standards measure and classify elevators and escalators according to their energy performance.The first part of the standard focuses on the assessment of the energy efficiency of lift systems. Based on the measurements and the final report, the elevators can be classified into efficiency categories ranging from A to G.

Our experts at TÜV Rheinland helped to test the in-use elevators in five main cities in China. Every elevator was tested with special high-precision testing equipment to monitor their energy efficiency status in normal operation situations and to record significant data for the final report.

With the information gained during the testing, the company can better understand its own products, not only in laboratory circumstances, but also in normal daily use.

Founded more than 140 years ago, TÜV Rheinland is a global leader in independent inspection services, ensuring quality and safety for people, the environment, and technology in nearly all aspects of life.

We inspect technical equipment , products and services, oversee projects and help to shape processes for companies around the world. Since 2006, we have been a member of the United Nations Global Compact to promote sustainability and combat corruption.

Our extensive experience in the elevator industry helps ensure that your elevators are energy-efficient, safe and in compliance with all applicable standards and regulations. TÜV Rheinland can offer intelligent solutions for manufacturers and operators of machinery, equipment, and semiconductors with required testing processes.
