LEED CI 2009 M&V metering requirements

Our company is in the process of determining whether a commercial interiors project is ideal for the EAc3 submetering option for Case 1. The tenant occupies the entire building, but only seventy-two percent (72%) of the space will be renovated and considered for LEED purposes. Given these circumstances, does Case 1 only require one (1) building-wide electric meter, one (1) building-wide process water meter, and another building-wide gas meter to comply? After looking through the template, the mention of submetering for each energy end use leads me to believe that they do need to be separated appropriately. It should also be noted that the tenant receives their heating, cooling, and ventilation from a central plant that only serves the building that they occupy. Any advice or guidance would be greatly appreciated. Thank you, Patrick
