Lifecycle for lifts

We have had a life cycle analysis done for a 4-storey lift in a residential building. It clearly shows that the material used to manufacture the lift has a significantly greater negative impact on the environment than that from the operation of the lift during the life of the property.

In this example, both lifts are installed in a new residential building in Berlin. The hydraulic lift is then modernised every 20 years and the lift with counterweight is replaced completely at the same interval.

Environmental impact from the material

For most people in the elevator industry, the results are surprising. Until now, all focus has been on reducing energy consumption in operation and much has been improved here. But now it’s time to also look at the environmental impact of the material used.

Lift without counterweight in lower buildings

Our life cycle analysis clearly shows that it is most appropriate to have a lift without a counterweight for lower buildings, such as residential buildings.

37,000 kg less carbon dioxide emissions

We estimate the lifespan of a residential building at 80 years and the lifespan of the lift at 20 years. The environmental impact of a counterweight lift will then be 37,000 kg more carbon dioxide emissions compared to a hydraulic lift. The amount of carbon dioxide emissions is equivalent to driving a petrol-powered car that meets the EURO 5 emission requirement of 11 500 km,

Circular economy for lifts

Circular economy is an expression for economical models in a company, society or an organisation, which highlights business opportunities where circular ecosystems are used, rather than linear processes – that have dominated the business climate thus far.

Modernisation

Modernisation, or renovation of a lift, means that the lift is upgraded through the replacement of parts like drive unit, electronics and other wear and tear parts.
