[Equest-users] Different Hourly Values for Winter and Summer

[David Eldridge]

If the question is the hourly shift, it may be daylight savings time which would occur during the April dates and would be standard time in January and would normally switch to Standard Time around that date in October or early November. (Always occurs on a weekend as opposed to a fixed date.)

Check one week earlier in October and it may be the savings time again. You should be able to turn off DST in the Model simulation variables, I forget exactly which menu.

Hello all,
While looking at eQuest Hourly Results for lighting end-use I came across a situation where 24-hr lighting end-use had different values for WD during winter and summer. Please see the results below.

It looks like the values shifted roughly around the week of 4/7,  one hour upwards so overall usage remained the same every weekday but again changed to actual one on 10/28. Connected lighting load is 7.44kW and the schedule is as per column one,
There is only one schedule throughout the year[12/31]. I'm using the simulation year of 1996. I'm trying to estimate the average peak usage between 2 pm-6 pm. Since the values change between winter week and summer week, I'm unable to estimate exact peak usage. Any help would be appreciated!

Thank you
Siddharth
