Hi,
I'm working on a project with administration affectation and some commercial surfaces on the groundfloor (surface < 40% of the total project surfaces).
As the commercials will have a special interior design, must we, for all credits, verify the differents criterias or can we have a tolerance in the credits achievement ?
For example, concerning the daylight criteria, must we provide some glare-controle devices also for commercials or not ?
Thanks for your different answers,
Audrey

Is it possible to combine Options 1 and 2 for different spaces in the same building?
What spaces are considered regularly occupied and must be included in the calculations?
What daylight simulation software can I use for LEED compliance?
My office space will have cubicles with high partitions. Should I include those in my model?
What types of glare control are acceptable for this credit?
Do I actually need to submit the USGBC Daylight and Quality Views calculator?
Can electrochromic glazing qualify as a glare control device?

Hi Audrey,
For modeling the interiors, IES LM-83 recommends:
2.2.11 Furniture and Partitions Furniture and opaque interior partitions shall be modeled.
1. Any partition or furniture element extending 36" above the floor or more shall be modeled to within 6" accuracy.
• If furniture layout and type are not known precisely, a typical furniture layout for that space type should be used.
If your space does not have any furniture above 36" than you do not have to model any furniture.
You should put on a shade for modeling your sDA score, but in practice if your ASE score is low with a good passive design strategy or electrochromic glazing you will not need any shades for your building. Some software models shades automatically for you to produce an accurate sDA score.
For documentation if your ASE score is > 10, then you should recommend another glare control strategy for your interiors. E.g. if in the commercial building someone was working at a register and could not move, yet had glare, what could they do to mitigate it?
