[Equest-users] Clerestory and Daylight Saving

[Nicholas Caton]

As a confessed lighting nerd I'm a serious proponent of the cool things you can achieve with SPOT (including pulling advanced analysis hourly outputs back directly into a doe2/equest energy model) but there are also many times when serious daylighting controls accuracy isn't really a requirement.  If that's the case, you can leverage eQuest to estimate daylighting "through" plenums by creating an effectively-adiabatic exterior wall construction (R-100 or similar levels of insulation), create an exterior surface as a child component for the occupied zone you're targeting, then play with the geometries/orientation to get the window you'll put on that surface up above the roofline and facing the correct direction.

Whether you go super-accurate with SPOT or estimate with eQuest, be mindful to consider any rooftop elements beyond the rooflines (like rooftop equipment, buildings across the street, tall trees) that would obstruct direct daylight into the clerestory.

Best of luck!

Thanks David! I'll start toying with that to see if I can figure it out.

If accurate daylight savings is warranted, I usually turn to SPOT. It creates accurate lighting schedules which can be directly imported into eQUEST via BDL. Keep in mind, SPOT assumes everything is optimized and running perfect, so it has a tendency to over estimate savings.

Hi folks,
I was wondering if you know of a work-around for adding clerestory and proper daylight saving in a building with plenum in eQUEST?
Clerestory is basically a vertical window on the high section of the wall to bring daylight into the building.

Thanks
Ali Mo, EIT
