The tenant guidelines can help build a sense of partnership on sustainability goals between the LEED-CS and LEED-CI teams. As one benefit to this, the tenant may be willing to split the cost of certain items that will help attain LEED-CI. Some items to consider splitting costs on may include:

water-efficient fixtures,
measurement and verification or submetering systems,
bike racks and showering and changing facilities,
upgraded lighting or mechanical equipment,
or commissioning.
