Urban Land Institute’s (ULI) Tenant Energy Optimization Program demonstrates how energy efficiency can be integrated into tenant space design and construction to deliver financial benefits through energy conservation. The program is based around a ten-step process that guides building owners through each phase of an energy optimization project, from pre-lease through post-occupancy. This ten-step process was tested, refined, and documented in ten pilot project case studies, which detail the experiences and lessons learned through the tenant energy optimization process. To further support adoption of the tenant energy optimization process, ULI has produced countless tools and resources that can be utilized to replicate successful projects.
