Hi all,

I have been working on the LEED energy model for an office building. There are different sizes of the offices in the building. It would be appreciated that anyone can let me know if there is a benchmark to differentiate the enclosed office and open plan office. I'm using the space by space method and about to assign the templates.

Thanks,

Chenlu

I would assume that enclosed offices have a door to them while open offices don't really have a door except to enter the space itself from a corridor or something similar. An open office space also tends to have systems furniture and multiple occupants in the space while an enclosed office would typically have one occupant. There could be some grey area here so use your best judgement. If you are not sure you will want to be conservative by selecting the space type with the higher LPD.
