FAQs about IEQc7 :

ASHRAE-55 comfort criteria ask for space air speed. Is this the same as the supply air volume measured in cubic feet per minute (CFM)?


What should I do about a warehouse space?

How can thermal conditions for areas with metabolic rates outside of 1.0–1.3 be determined? (Per ASHRAE Standard 55-2004 Section 5.2.1.1, Figure 5.2.1.1 can be used for areas with metabolic rates between 1.0 and 1.3).

There are a few spaces in my project that can’t meet these requirements. Can’t I just exclude them?

We are working on a C&S project. The Design team states, "The tenant spaces are typically served by roof-mounted central station variable air volume (VAV) air handling systems. Capped connections have been provided for future fit out connection. The future tenants will connect terminal VAV units to serve each space as required for proper control and operation of the system." My reading of this is that the tenant will be installing some of the mechanical systems of the project. If you click this on the template, the templates states that the credit cannot be achieved. Is this a correct understanding? Thanks, Sam

I have the same doubt. Had someone answered this question before? Thank you! Gabriella

I do not see any responses to this thread. Has anyone achieved IEq c7 under 2009 CS when the base bldg provided the only air units, but not tenant ducts, boxes air devices?

The situation is different here. Since you have provided the AHUs, which provide ventilation air and conditioning, you are eligible to meet the credit. The lack of a full distribution system is pretty typical.

Thanks Christopher. I have the exact same situation, where C&S is installing the AHUs, chillers, boilers, and all duct mains onto each floor. We are not providing the distribution ductwork or VAVs to the tenant spaces. The only areas we are delivering comfort cooling/heating are the core areas. That being said, I was only going to document the space design conditions for these core areas and back it up with a narrative. Does that sounds like a viable method? Thank you
