Technologies for clean mobility

Seemingly small and insignificant measures can have a significant effect on elevators' and escalators' environmental performance during their operational life cycle. The analysis of individual components is therefore just as important as the analysis of the entire system. Through intelligent solutions and the application of new technologies, we have been able to make significant progress in the reduction of energy and material use.

Environmentally friendly elevators start with the design

First we analyze, then we advance

Our approach to the environment mirrors the way we approach our business overall. Schindler systematically analyzes its activities and focuses on those areas where we can have maximum effect, such as energy efficiency.

We conduct life-cycle assessments (LCA) of our products. The objective is to continuously improve the environmental performance of the product assessed. 

As a result of the ongoing development of products, Schindler has, for example, been able to decrease the energy consumption of the Schindler 5500 product line by up to 50% compared to the previous model.

Environmentally friendly elevators

With the introduction of the Schindler 3300 and the Schindler 5500 elevators, a technological leap was achieved, reducing the environmental impact of earlier commodity and commercial product lines by about 40%. This reduction was achieved primarily through energy savings, for example switching the standard car light from 'always on' in the previous product lines to 'automatic off' in the newer ones.

The Schindler 7000 high-rise elevator is used in skyscrapers and other high-rise buildings throughout the world and provides energy savings through the development of significantly lighter components, the optimization of the energy levels required to light the elevator cars and for electronic standby functions, as well as the recuperation of energy while the elevator is running.

Environmental Product Declarations correspond to the ISO 14025 standard

Increasing energy efficiency is essential in order to reduce the environmental impact of the elevator and the building. To give insights on the ecological performance of its elevators, Schindler provides Environmental Product Declarations (EPD) which correspond to ISO 14025. The longest phase in the life cycle of an elevator is the usage phase, which can be up to 30 years, depending on maintenance and modernization. The energy consumption during this phase is assessed in accordance to ISO 25745-2.

Applying ISO 25745-2 for the energy calculation and classification of elevators

Schindler employs the ISO 25745-2 standard to provide accurate and relevant energy consumption information for its products. This standard has been published by the International Organization of Standardization (ISO) and is an internationally accepted standard in the market.

Purchasers prefer a single figure to rate the energy efficiency of products. However, an elevator uses both operational energy and standby energy. In the commodity market, where usage is relatively low, the standby energy can account for as much as 80% of the total energy used, whereas in elevators that are in frequent use the drive system is responsible for a major proportion of the energy used.

The ISO 25745-2 standard lists different usage categories. Standby energy and operational energy are weighted depending on the way in which the elevator is used, in order to come up with a single figure. Once this figure has been obtained, it is possible to assign an energy efficiency class from A to G, with A being the most energy efficient.
