IEQ 6.2 Controllability of Systems - Thermal Comfort

Hi Sandra,
I do not believe the credit requires individual thermal comfort control for the visitors. While the credit language uses the term "occupants", the reference guide mentions only areas where FTEs would be present (offices, reception desks, etc.). So yes, the back offices would need to meet the 50% requirement. The sales areas are classified as a multi-occupant spaces (this is supported in the IEQ Space Matrix developed by USGBC). Hope this helps.

Hi Sandra,

You've hit on a tricky scenario. Currently LEED for Retail doesn't exist for Core and Shell projects. However, I would still take a look at LEED for Retail for general thoughts and guidance. Please go here: http://www.usgbc.org/ShowFile.aspx?DocumentID=8870 (page 75). The language states: "Provide individual lighting controls for 90% (minimum) of retail employees in office and administrative spaces, enabling adjustments to suit individual task needs and preferences.
AND
Provide individual thermal comfort controls for 50% (minimum) of retail employees in office and administrative
spaces to enable adjustments to suit individual task needs and preferences." Granted, your reviewer may or may not take this approach seeing as your project is not registered under LEED for Retail but I think you could make a strong case for using the approach outlined in this system while referencing the limitation of currently not having access to a LEED for Retail for Core and Shell.

I worked on one LEED-CI project that wasn't registered as LEED-CI Retail but we still used some of the language successfully from LEED-CI Retail in our approach for EQc6.

Is your project's scope including the mechanical controls? I'd just make sure to review this language from the LEED-CS 2009 Reference Guide which states: "Core and shell projects that do not purchase and/or install the mechanical system or operable windows (or a combination of both) have not met the intent of this credit."

Further, I often include a potential floor plan layout for reviewers breaking down the space plan for your Core and Shell space with notations indicating the thermal comfort controls.

I agree with John that the shoppers in the mall wouldn't need to be included. However, part time employees and full time employees would.

Hope this helps a bit. Any other LEEDuser forum members have additional advice or experiences they could share?

sorry, LEED for Retail is found here: http://www.usgbc.org/ShowFile.aspx?DocumentID=7956
and not in the original link I provided.
