[Equest-users] Help needed regarding results.

What you are proposing is in fact a very sophisticated/complex problem with a lot of interactive variables in play.

You may need to share the project file to help others on the list determine what is awry with your inputs, if you are still having issues.  If daylighting is applied to spaces with fenestration, you should certainly see a direct effect on lighting consumption and likely also indirect effects on fans/cooling/heating enduses as you vary WWR.

Recommended reading for a very similar study is attached.  WinOpt is a derivative of GenOpt specifically leveraging the energyplus engine, though note GenOpt is “engine-agnostic” and this study could have been alternatively performed with doe2/eQuest.  

I might also suggest that you might consider further selection of your “optimum” results to consider first-cost of construction (as a function of WWR and the various glazing fenestration unit selections), and also to consider recording the effect on (and perhaps constrain by a cap for) unmet heating/cooling hours that occur with various optimization variable combinations.

In detailed edit model you can go to space-daylighting and then choose "yes" for daylighting. You can specify the schedule and control type over there as well. Hope it helps!

Hi ,

I have turned on the day-lighting controls in wizard 1  and retained the default data for day lighting in further wizards. But is there any other way to turn on day lighting for the zones? or any other wizards where i have to take care of  daylighting

Hi,

Did you turn on the "daylighting controls" so that the model considers daylighting in calculating the lighting load? If you turn on the "Daylighting controls" (Wizard Screen 1/41)  , only then eQuest will model the daylighting savings. WWR can be set only in the wizard mode. I believe it requires little advanced knowledge to implement parametric runs for WWR in eQuest detailed mode.

	Hello everyone,

	I have been doing an academic project where i am trying to find out the best percentage of facade glazing which results in optimal energy consumption in IT office building.

	Is there a possibility of doing parametric studies pertaining to change in facade glazing percentage or lets say WWR.

	I tried a floor plan with three different types of glasses and different percentages.

	But as i reduce the facade percentage from 100% to 30%  the energy consumption report says that there is reduction in energy consumption.but There is no difference in lighting loads . the only change in the report is for space cooling. The reduction in the glazing definitely results in increase in lighting loads in a fully conditioned office building.  

	This is not being projected in the results.could some one help me on how to proceed in this regard.

	Thanking you,

	P.Sitha

	Pursuing M.Arch
