Hi,
My read of LEED 2009 -CI v3.0 EApre2 is that only applicable sections of the ASHRAE 90.1 or California Energy code would apply to the new components of an HVAC system serving a tenant improvement pursuing LEED CI v3.0 certification.

So any efficiency requirements for the base building HVAC (mechanical equipment) would not apply if there was no plan to replace the equipment but only to re-duct the system and add better controls. The existing equipment uses HCFC refrigerant and so meets the intent of the EApre3 measure.

Is this a correct assessment of the prerequisite requirement in terms of existing HVAC equipment?
