Unmet Hours

Escalator Schedule

For elevator schedule, I normally use Example Operating and Occupancy Schedules in ASHRAE Standard 90.1 User's Manual. Below is the case of office buildings. Maximum power (Rated power) of elevator is multiplied by this percentage.

But how about escalator schedule? Can we use the same schedule as elevator? I'm a little concerned about it because elevators stop and move, and there are peak hours and infrequent hours, but I think many escalators are always moving at the same speed.

Does anyone know reasonable escalator schedules (as a percentage of rated power) or any mention about it from ASHRAE? Or should we use "1"(100%) as the escalator schedules during all business hours?

I searched patiently and found one basis of escalator schedules.

ANSI/ASHRAE/IES Standard 90.1-2016 Performance Rating Method Reference Manual states:

NACM(Nonresidential Alternative Calculation Method) issued by CEC(California Energy Commission) describes Schedules in Section 5.4 Space Uses as follows:

Appendix 5.4B is here. I put the downloaded excel files here in case the link to the website breaks.

In Appendix 5.4B, elevator schedules and escalator schedules are specified separately for each building type, and the escalator schedules consist of a fraction of 0 or 1. The following table shows only the escalator schedules for each building type I extracted from Appendix 5.4B.

I just updated the summary table of escalator schedules above as I found the schedule for Restaurant was incorrect. The original NACM Appendix 5.4B is correct.
