Abstract: Most widely adopted rating systems place the highest importance on energy efficiency and consumption models however do not require life cycle cost analyses (LCCA) or occupant feedback and post occupancy evaluations (POEs). LCCAs are a pivotal component in ensuring sustainability features selected on projects (horizontal or vertical) truly provide the benefits promised. However the implementation of accurate LCCA analyses depend on the validity of information used in the LCCA model. Accurate LCCA models can only be generated if POE data is collected, analyzed, and shared with stakeholders. This paper examines several topics: why post occupancy evaluation (POE) performance measurement must be implemented to paint an accurate LCCA picture to facilitate clients decision making process, what are POEs and methodologies to perform them in LEED and non-LEED projects, stakeholders who must participate in the POE and LCCA process, the feedback loop needed to ensure repeat mistakes are not made, contractual language needed to gather and analyze POE data, and how project controls professionals should be the front runners in this process increasing their service line offering.
