ASHRAE 90.1-2010 added VRV systems so the HVAC form with that version would deal VRV systems if you are looking to find out the minimum best practice for those systems. Since VRV systems are not covered by 90.1-2007 there are no provisions to comply with specific to them. In essence they are exempt from any specific mandatory provisions such as minimum efficiency.

Marcus, correct me if I am wrong, but there is an addendum (Cp) to ASHRAE 90.1 - 2007 which deals with VRV systems. Can this be used?

Not sure about the addendum that added these systems but in general you can use addenda to 90.1-2007 as long as you apply them in their entirety.
