[Equest-users] space renaming

You can easily justify over 100 zones on larger projects (say 50,000 ft2 or more), especially if they are not multi-story with identical floor plans. Most of the modeling I do uses Appendix G methodology, where lighting power density is assigned by space type. I use a keyword expression to assign LPD based on the space type, as assigned via the C-ACTIVITY-DESC space keyword. This makes it easy to accurately model LPD and to provide documentation for LEED submissions. However, it only works if you define zones as the smaller of the HVAC zone or the space type. (You can't combine a classroom, bathroom and storage room into one space even if they are effectively one HVAC zone.)

I also feel 476 spaces are way too much. I can understand that some projects have different floor plates & plans and it can end up resulting more number of zones. But trust me the more number of zones, more complicated it gets. I did one project with almost 150 zones (multi family high rise building) and later when I moved to detailed mode  it was a pain to make changes for spaces/zones.

I would suggest rather creating separate zones for same user type spaces facing same façade, you can combine them as one single zone each floor. For corner rooms/spaces, create separate spaces. Try to keep it under 100 atleast.

Hello Wafik.

One question you might ask is why you have 476 spaces in EQUEST?

Normally, a space is needed only if that zone has a unique load, usage, external exposure or HVAC system. Otherwise, it is more common to use a simplified zoning. For example, 5 zones are normally used for a rectangular building of more than 50 ft in depth. At most, for a multistory building, three floors can be used, one for the top floor, one for the middle floors, and one for the ground floor.

Hence, you might consider reducing the number of zones before proceeding.

good day every body,

what  is the fastest and easiest way to rename about 476 space in eQUEST model.
instead of going one by one then doing the same for the thermal zones!
whats the best way to name both  using the wizard without having any errors?
is there is any shortcuts?

regards,
Wafik
