Do I have to achieve Option 1 if I want to pursue Option 2?

Has the pressure differential requirement of at least 5 pascals for LEED 2009 EQc5: Indoor and Chemical Source Pollutant Control been eliminated from the requirement of this credit?

How can a Core & Shell (CS) project to comply with the credit requirements if they are not in the project scope?

Hi,

I'm working on the LEED C&S certification of a new shopping centre where the majority of retail and restaurant space will be shell or 'grey box' with no HVAC installed.  Only landlord areas will have installed services.

In the case of Fundamental IAQ, the LEED manual states the following:

"If the scope of the core-and-shell project does not include mechanical systems, the project is exempt from the ventilation and monitoring requirements"

Does this exemption also follow on for Enhanced IAQ including requirements for Entryway systems?

Most forum discussions on this topic seem to point to the use of a signed TSLA for Entryway sytems.

This would not be practical on a large new development - there is little chance that every unit would be 'let' by the time the submission would be made to USGBC.

Should shell areas with no HVAC be exempt for the requirements of Enhanced IAQ criteria?

Any guidance would be appreciated,

Thanks,

PJ

Hi PJ, For Enhanced IAQ, entryway systems only need to be provided for main exterior entrances (including parking garage entrances) that are completed as part of the CS project. Future tenant retail spaces are generally subject to reconfiguration (and possibly addition of vestibules) and these systems would be part of the tenant scope of work. Cam
