[Equest-users] daylighting in equest

[Yuvaraj Saravanan]

Yusuf,
You may have to model all other intermediate floors if each floor has different functionality, systems and loads. The multiple floor option is only useful if you have typical functionality, internal load and system type.
Regards,

Subject: [Equest-users] daylighting in equest

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
