[Equest-users] daylighting in equest

[Yusuf Turab]

Dear Members

              On my second day, I have now got a hang of the basics of the
eQuest s/w. After running a few sample simulations of a very basic building
I noticed the following:

   - My fully air conditioned building with a 30% WWR returned a total
   consumption 1545 units of energy and my lighting was 149 units. Then I
   removed all windows making the WWR 0%, my total total consumption went down
   to 1520 units but area lighting was still 149 units. How does eQuest
   account for daylighting? If my building has no windows or skylights then
   the lights have to function overtime, so how is my area lighting
   consumption still the same? The gains that I make in the cooling; should
   that not be mitigated with the lack of daylight?


   - I understand that for multi-storey buildings, eQuest considers only
   the top, ground and all middle floors are only considered to be one floor
   and the result is simply multiplied to show the final performance. How does
   that work? Every floor in a building might have different functions,
   different internal loads, systems etc. How can equest only model one floor
   and multiply the result. Would this not be inaccurate?

Thanks in advance
