Building transportation systems
Minimise transportation requirements through good building layout during the sketch design stage
- lifts located close to well-signposted staircases so that potential passengers can easily choose to use the stairs rather than the lifts (2 - section 13.9, 1 - section 11.5)
- lifts grouped together to increase the number of passengers per journey hence reducing the total number of journeys (2 - section 13.9, 1 - section 11.5)
Design energy efficient escalators and moving walkways
- variable speed drives that reduce speed when traffic is light (2 - section 13.9, 1 - section 11/05/02)
- automatic start-up and stopping of escalators so they operate only when there is a demand (2 - section 13.9)
Estimate/predict and benchmark energy use
- predicted energy use of alternative system designs compared against each other (2 - section 13.6, 13.7)
- estimate energy use of proposed system design compared against "example" energy benchmarks (1 - table 11.6, 11.7)
Implement an energy efficient lift traffic control strategy
- heat recovery from lift motor rooms if the lifts are used intensely (2 - section 13.9, 1 - section 11.5, 2 - section 13.9)
- minimum passenger waiting time during off-peak periods of interfloor activity during the working day (1 - section 11.5)
Consider options available to reduce energy demand of lifts and escalators
- lift control strategy that minimises the number of lift movements (1 - section 11/05/01)
Design energy efficient vertical transportation (lift) systems
- lift speeds appropriate to the task, e.g. slower speeds for goods lifts (2 - section 13.9, 1 - section 11.5)
- energy efficient lift drive (2 - section 13.9, 1 - section 11.5)
- regenerating lift drive system with electricity meter capable of recording exported energy (2 - section 13.9, 1 - section 11.5)
- heat recovery from lift motor rooms if the lifts are used intensely (2 - section 13.9, 1 - section 11.5, 2 - section 13.9)
