The New Mexico Public School Facilities Authority (NMPSFA) is the agency responsible for administering state-funded capital projects for schools statewide. Post occupancy evaluation (POE) is the tool selected by NMPSFA for measuring project outcomes. The basic POE process for V. Sue Cleveland High School (VSCHS) consisted of a series of field investigations involving survey implementation, interviews, observations, focus groups as well as space condition assessments using dataloggers and hand held meters. The resulting data, combined with utility and demographic data on the students, teachers and staff, was then analyzed to provide a comprehensive building and occupant side picture of the facility. This process is applicable to any school environment and most facilities in general. Using the post occupancy evaluation (POE) case study for the V. Sue Cleveland High School (VSCHS) in Rio Rancho, New Mexico, as a primary example, the authors discuss selecting and implementing the proper tools for measuring school building performance.
