Hi there,
Our project is a shopping mall which will include process loads such escalators, lifts and IT equipments. The total demand load (KW) for these systems is easy to get from the Electrical Engineer.
However, it is much more challenging to obtain the annual consumption of - say - a lift or an escalator equipped with energy saving sensors. Should we assume that such systems will always be working at full capacity during opening hours? If so, this will have a terrible impact on the yearly energy consumption.
Can I find an online database showing typical escalator and lift use pattern in shopping malls?
Any hints would be welcome...
Many thanks,

Yep do not assume full capacity, 24/7 operation.
For escalators I would consult the manufacturer. The schedule is pretty easy to determine. Not sure if they use more energy with a large people load or not.
For elevators you can use the data in the 90.1 Unser's Manual, Table G-L Retail Occupancy for a default schedule.
