[BLDG-SIM] eQuest Clerestory Skylights

Brandon,

In the detail mode, instead of creating a new space, add the doghouse to the space itself where you want to see the benefits of daylighting. Right click on the space, go to 'create child component' and then click on 'create exterior wall'.

Define the walls in the manner such that they sit on top of the roof of the space below. As the doghouse is not a separate space so there will be no floor or even a roof - it is a set of vertical walls with windows sitting on top of the space.

You can do the same even in case of a space with a plenum.

Best regards,

Gaurav Mehta

Subject: [BLDG-SIM] eQuest Clerestory Skylights

All,

Am looking for some insight into doing clerestory skylights with eQuest. For clarification, clerestory skylights are essentially vertical windows, sitting in a "doghouse" if you will, on top of the space served.

While it is interesting, I'm not sure I fully understand what eQuest is doing what it adds horizontal skylights in the wizards. Evidently if the space served has a plenum, a "dummy" roof needs to be defined for the actual occupied space, else skylights will illuminate the plenum. Turning these Wizard-inserted horizontal skylights into the clerestory types mentioned above I have reservations attempting in the detailed editor.

But what if there is no plenum? While in the detailed editor I would like to add the simple doghouse shells with side-windows and a floor of "air", then cut away the roof of the space it sits atop of and enjoy daylighting calculations -- but something tells me the space below may not receive the benefit of the daylighting... that perhaps the daylighting will be applied only to the space within the doghouse and not transmitted to the space below, regardless of the fact that the floor is "air" and there is no ceiling in-between.

Does anyone know if these concerns are valid, or perhaps of another approach for modeling the aforementioned clerestory type skylights? One thought that comes to mind is to simply take the Wizard-inserted horizontal skylights and rotate them 90°, but I am unclear about what other measures would need to be taken to assure accuracy.

Thanks in advance
