[Equest-users] High cooling consumption before lights level are decreased

[Sharad Kumar via Equest-users]

Hi Fakeha,

This is the second mail today.

You might be knowing that when you decrease the lighting schedule the
lighting load decreases so as the heating part of lighting load.
There is no normal reason behind what are the real factors causing it.
Following can be the cases:

1. Due to low cooling set-point as well as higher lighting fraction
schedule there can be easy way to know why there is higher cooling energy.

2. Maybe as the lighting fraction and the cooling set-points are matching
in the case of 2 pm to 5 pm to have the low cooling consumption.

3. May be the duration between 11 am and 2 pm is the time where there is
too much possibility to have the higher cooling consumption as the
condition matches to have the higher cooling load but you are unable to
resolve it so might be it depends upon your model or something so that in
this case of 11 am to 2 pm the cooling consumption is higher.

4. Another reason can be that there can be the possibility in this case
that the duration, schedule, time ans set-point is such that that it is
able to have the cooling consumption going higher in this case.

I'm unable to predict more but others can may help.

*Thanks,*

Hi,

When I raise my building's cooling set points from 2pm to 5pm,I observe for
a summer day that the cooling consumption goes low during this time; which
is fine. Now when I reduce the lighting schedule values (in order to reduce
the lighting load) from 2pm to 5pm lighting consumption goes low during
this time but for some reason the cooling consumption gets higher before
around 11am to 2pm, why?

Regards
