In the reference book, under IEQc1 point 4. Implementation, it states that "This prerequisite is not limited to the project scope of work." Could someone please clarify exactly what this is referring to?
It refers to the building HVAC system supplying enough air, and also location of air intakes within this paragraph.
Currently I have a new system that is serving spaces that fall under the LEED scope, and spaces that do not. Do all spaces need to be included for compliance since the Ventilation Rate Procedure looks at both individual spaces, and the system as a whole? While spaces outside of the scope wouldn't count towards the credit, they could change the system ventilation efficiency.
Does anyone have an experience with this?

Michelle, you'll have to consider all spaces associated with the HVAC system, in order to determine the proper ventilation efficiency (Ev), as you mention. The main purpose of the comment in the reference book is that even if base building systems are outside of project scope, the project still needs to comply with ASHRAE 62.

I understand that the project spaces need to comply with ASHRAE 62.1, if the systems serving the space was installed as part of the LEED scope or not.
Are you saying that a project would need to perform a calc on each and every space that is served by an existing system? I am working on a job where the base building system serves 10 other floors of the building, it seems unreasonable to think that our engineers would need to first understand the distribution system throughout the rest of the building and then to calculate the ventilation rate in all of those spaces...for a pre req????
