Help with Interpretation!

I have the same fuzziness as Robin, the reference guide is unclear about base building systems. Please help. If our project is providing most of the HVAC from dedicated units but the restrooms and hallway have base building HVAC from uncertain equipment....what do we do?

Hi Sue, I think this question is answered below under the heading "help with interpretation." Let us know if you still have questions after reading this.

Well not really- I still read the LEED CI 2009 Reference Guide to exclude the base building HVAC.....if it is not in the LEED Scope of Work. I'd like to know if I'm understanding it correctly because your answers indicate that everyone thinks the base building needs to be CFC free. Or in my case- the district heating and cooling system....

This has not been update for LEED 2009, but you may find it helpful to review the LEED guidelines for district energy.Based on that it seems pretty clear that you are off the hook here.

John, I had dialogue with a USGBC contact about this, and confirmed that  the requirement is, as the language (see above) states, “Zero use of … within the LEED project scope of work.”  Under Implementation, the Reference Guide states, “only HVAC systems built for the project are within the scope of work,” even though base building systems are mentioned above that.If the tenant does anything to influence the base building system, then it becomes part of the tenant scope of work, but would appear to otherwise be outside of it.See my related comment below about fire suppression systems.
