Nick,

Thanks again. Can you stack a space in a zone?

Thanks,

Peter, I think you might be leading yourself into some unnecessary confusion with your word choices...

eQuest has 3 distinct entities:

-          Shells are simply groups of spaces

-          Spaces are geometrical volumes, which may or may not have floors, walls, ceilings, windows, etc. tied to them.  Internal loads / daylighting / occupancies are attributed to spaces.

-          Zones are simple entities that include one or more spaces, with additional HVAC attributes like thermostat and airflow specifics.

You're using "floors" to interchangeable discuss all the above, it seems.  For clarity when discussing eQuest, "floors" are merely the constructions we walk on, normally one attribute of a "space."

All that said, it's entirely possible to model a "box within a box," as you're describing.  You are limited in the wizards (by their nature) with regard to defining zones/footprints... the best approach depends on the nature of the space footprints you want to model.  If it's very simply two stacked cubes enclosed within a larger cube, I'd personally model one shell, with one space carved out of the middle.  Then I'd use the detailed mode to shrink that space volume and partition/ceiling dimensions to match the first floor office, then copy the entire space and its componenents for the second floor.  I'd adjust the largest cube's volume (it's a space property) to correct the conditioned volume, and be sure all partitions are correctly associating the three spaces together...  With all spaces sorted out, ensure your three spaces are correctly grouped with regard to "zones," for association with your HVAC system(s).

Clear as mud =)?

To All,

I just want to make sure I understand the properties behind floors. If you have a square building volume with a smaller square inside it that has 2 levels. EG:- an atrium as main space with 2 levels that are offices. There will be a total of 3 floors in your model. Atrium floor, first floor office and second floor office. Each of these will have a designated floor to floor height. You cannot put one zone inside another on the same floor.

Is this correct?

Thanks,

PETER HILLERMANN
