We have a hotel building (600,000 sf) and a convention center (150,000 sf) which are connected by a 300-400 feet ong corridor. The 2 buildings have the same owner, will be built by the same contractor and will under the same hotel operator. We want to go for LEED silver for both building but want to register both of them as one project (eg. : X hotel and convention center), will this be ok or we need to register them separately ? Please note I am not asking to go for group project and my question is regarding registering the 2 buildings as one project.
