figure 5 P O s t- O c c u Pa n c y e va l u at i O n The first post-occupancy survey was conducted in January and february 2003 (n=500). The fourth survey was conducted in october 2007 (n=650). The benchmark data includes 430 buildings (n=47,929). O c c u Pa n t s at i s fa c t i O n A Web-based satisfaction survey administered to Block 225 occupants provides additional information on actual building performance. The survey addresses occupant satisfaction for seven environmental categories, as well as two questions on general satisfaction with the building and personal work space. The survey has been administered to nearly 48,000 occupants in 430 buildings of all types and sizes, creating a large benchmark database. four post-occupancy evaluation (Poe) surveys have been completed since the building was occupied in July 2002. Figure 5 compares average occupant satisfaction ratings for the most recent Poe (october 2007) to those of the first Poe (January/ february 2003) and the large benchmark database. response rates for both Block 225 surveys were close to 50% and were a fair, representative sample. The survey results are generally positive, considering that Block 225 is a large open plan office building. The results for the fourth Poe indicate that occupant satisfaction has increased significantly in most categories since the first Poe. Three categories (general building, thermal comfort, air quality) were likely influenced by the existence of the ufAd system and the recommissioning and tuning up of the building’s HVAC operation. floor diffusers give occupants a sense of personal control while increasing air movement and available fresh air. All categories were rated above zero except acoustic quality in the october 2007 survey. The acoustic quality rating is not surprising for a large open plan cubicle layout and is a contributing factor to the average or below average ratings for general workspace, office layout, and office furnishings. improvements to the task lighting resulted in a large increase in satisfaction with lighting quality. The decline in satisfaction with cleanliness/maintenance and, to some extent, air quality since the first Poe is likely due to the building’s increasing age. fa l l 2 0 0 9 HigH Performing Buildings
