Lifts and building safety - evacuation and use by firefighters by Nick Mellor (Lift and Escalator Industry Association)



As the impact of climate change becomes ever more visible, society appears at last to be reacting and making changes aimed at mitigating its impact and protecting our established ways of life.  Most if not all of human activity affects our planet, and the creation and modernization of buildings is no exception.

The lift and escalator industry therefore has an important part to play in minimizing the impact of its activities on our climate; the creation of new lift and escalator equipment consumes energy which is quantified by its embodied carbon credentials, whilst the use of lifts and escalators consumes energy characterised by its operational carbon credentials.

These carbon credentials play a key part in the broader assessment of a building’s energy performance and as an industry we now need to recognize this fact and refine both the processes and the accuracy with which we model the impact.

This paper explores the current guidance and assessment methodologies touching on such established documents as the Chartered Institution of Building Services Engineers (CIBSE) TM54, and the International Standard ISO 25745.  Application of these methodologies will be reviewed against a real-world case study, and conclusions and recommendations presented on how the industry might refine future assessments towards more realistic results.


Abstract for Lifts and building safety - evacuation and use by firefighters

Secondary legislation under the Building Safety Act and the Regulatory Reform (Fire Safety) Order have introduced new requirements for providing key building information and checking the functionality of lifts for use by firefighters and evacuation lifts.  These rest on identifying the types of lifts and their expected operation.

Improving building safety from the perspective of building occupants with specific evacuation requirements might include being able to use evacuation lifts independently.  This poses a challenge for specification of evacuation lifts for new buildings and for improving existing lifts to provide for evacuation.
