EAp2 - Compliance to ASHRAE standards

Hi all, we are willing to pursue LEED CI certification for our office in Italy. The only alterations we intend to do are the following: • install new water closet features, • install new lighting and lighting sensors, • install new carpeting, and • some other small improvements. We are not making any change in the envelop nor in the HVAC/service water heating systems. My question is: as per EAp2, do we still have to comply with ASHRAE 90.1-2007 sections related to HVAC, envelope, etc. or shall we consider only those related to our scope of work (i.e. section 9.4)? Thank you very much in advance for your help.
