A landlord who has constructed or renovated a building to meet a given green building certification protocol, such as the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Green Building Rating System, should develop interior fit-out guidelines for incoming tenants to achieve and sustain energy efficiency goals and preserve the integrity of the building. 

These guidelines might specify, for example, that construction in tenant spaces shall conform to LEED for Commercial Interiors and must be performed by experienced green contractors and subcontractors contained on a pre-approved list.  A landlord might also want to include in the interior fit-out guidelines for the building product and material specifications and a requirement that tenants employ a construction manager who is a LEED accredited professional.  In any event, the owner of a green commercial building, who is planning to rent it out, should carefully think though and plan the interior fit-out guidelines.
