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?

I am bit confused about the requirements of the Thermal comfort-desing’ credit for C&S Can you please help me on figure out if my building is eligible or not. The building is mechanical ventilated, I provide fans that will supply outdoor non-conditioned air for all the occupied spaces. Furthermore, there will be chillers and water cooling-piping in each tenant space, the way each tenant install their own equipment (fan-coil) thanks you

This credit is pretty clear. Look at the requirements and you will find: “Project teams that design their project for mechanical ventilation that do not purchase or install the mechanical system are not eligible achieve this credit.” Based on your description, you would not be able to pursue this credit, but the tenants could under CI if they design their distribution systems correctly.

It isn't that clear to me, in my opinion it is confusing because LEEDUser states: -"Base building mechanical systems have to allow for the tenant fit-out to meet the requirements of ASHRAE-55." This requirement is for the base building HVAC system, not for the tenant fit-out. and -"If ALL the mechanical systems are relegated to tenant fit-out, LEED-CS projects are not eligible". This is not your case Roland, because you are providing fans, chillers and water piping. Imho, since you are providing part of the HVAC system you are still eligible for this credit.
