Who will write the tenant guidelines? It could be the developer’s marketing team, the architect, sustainability consultant, owner, or any combination thereof. A collaborative effort is best. Each group has a great deal to offer and can provide varying perspectives and knowledge sets. Your marketing team may know how best to present the information to possible tenants, and your mechanical engineer should be able to explain the energy savings from mechanical equipment. See the Schematic Design section below for more detail on what needs to be included in the tenant guidelines, which can help you decide who should write them.
