Artificial Intelligence is being rapidly integrated into lift systems, supporting traffic dispatch optimisation, predictive maintenance and passenger-facing adaptive services. These developments have the potential to improve efficiency, reliability, safety and accessibility. However, these technological developments also introduce ethical challenges.

As decision-making becomes increasingly automated, questions arise about environmental costs, fairness in service prioritisation, passenger privacy, targeting advertising and the distribution of responsibility. As the building industry works hard to reduce carbon emissions, there is a risk that the computational demands of AI systems offset hard-won environmental gains.

This paper argues that lift systems represent a distinct ethical context. They are essential, safety-critical infrastructure embedded within buildings and unavoidable for many users. As such, the moral implications of optimisation, data collection, and automation in this domain require particular scrutiny. The paper calls for the cautious deployment of AI in lift systems and for maintaining clear institutional accountability for decisions that shape passenger experience, access, and safety.
