It is particularly concerned with the potential contributions of windows and daylight to improved performance by office workers. Two different studies were conducted at the same organization, the Sacramento Municipal Utility District.
The first study looked at workers in an incoming call center, whose performance was continuously tracked by a computer system and measured in terms of time to handle each call. The study sites provided a range of daylight, view and ventilation conditions, while providing a relatively uniform environment for other potential influences on worker performance.
All of the office work considered was computer-based, based on self-illuminated tasks. Multivariate regression analysis was used to control for other potential influences, such as age or employment status. A variety of statistical models were tested to determine if any of the variations in environmental conditions, either between workers or during different time periods for a given worker, were significantly associated with differences in worker performance.
Having a better view out of a window, gauged primarily by the size of the view and secondarily by greater vegetation content, was most consistently associated with better worker performance in six out of eight outcomes considered. Furthermore, office worker self reports of better health conditions were strongly associated with better views.
Those workers in the Desktop study with the best views were the least likely to report negative health symptoms.
Reports of increased fatigue were most strongly associated with a lack of view. Other variables related to view were also found significant. In the Call Total productive maintenance thesis higher cubicle partitions were associated with slower performance. In the Desktop study glare potential from windows was found to have a Total productive maintenance thesis negative effect on performance in three of the five mental function assessment tests.
Horizontal daylight illumination levels were found to have an inconsistent relationship to performance, significant in two out of eight metrics tested. Higher levels of daylight illumination were found positive for Digit Span Backwards, a test measuring attention span and short term memory, and negative when compared to changes in daily average speed of handling calls for one of two study periods.
The natural log of daylight illumination levels was found to have the best mathematical fit to the data, implying more sensitivity to changes at lower levels of illumination and progressively less sensitivity at higher levels.
Ventilation status and air temperature were also found to have significant, if intertwined and occasionally contradictory, associations with worker performance.
When variation in hourly performance at the Call Center was considered, higher rates of outside air delivery were significantly associated with faster handling of calls. Overall these potential influences on worker performance were found to have high statistical significance in the models tested.
Furthermore, changes in the physical design of a space that may influence worker performance are likely to have great persistence, continuing for the life of the building. When compared with the costs, persistence and the certainty of other methods of increasing productivity, constructing well-designed buildings may be attractively cost-effective.
As demonstrated in the study site, these same features can also provide additional energy cost savings. Both studies successfully measured variation in office worker environmental conditions and related these to measured office worker performance under actual employment conditions.
The Desktop study pioneered the use of computerized cognitive assessment tools to gauge office worker performance in field conditions. The studies have shown that indoor environmental conditions can have a measurable relationship to changes in office worker performance and have established a range of likely effect sizes that other researchers can use to refine the needs of future studies.
Other studies will be required to test if these findings can be replicated in other settings and to explore potential causal mechanisms between the environmental conditions and worker performance. Numerous other physical attributes of the classroom were also investigated as potential influences, including ventilation, indoor air quality, thermal comfort, acoustics, electric lighting, quality of view out of windows, and the type of classroom, such as open or traditional plan, or portable classroom.
Previous Studies This study is the third in a series of studies looking at the relationship between daylighting and student performance. The first, Daylighting in Schools,  which was completed for Pacific Gas and Electric inexamined school districts in three states.
A second study, the Daylighting in Schools Reanalysis Report  completed for the California Energy Commission in further investigated the results from the Capistrano school district. We investigated whether better teachers were being stationed in more daylit classrooms, and thereby inflating the importance of the daylight variable.
In that district, we found that there was no assignment bias of better teachers to more daylit classrooms. Furthermore, the addition of information about teacher characteristics to the original student performance models did not reduce the significance or magnitude of the daylight variables.
We also wished to understand how other aspects of the indoor environment affected student performance and interacted with daylight. To accomplish these goals, this study gathered detailed information about classroom conditions, including lighting and daylighting, HVAC, ventilation, windows, surface coverings, view, and indoor air quality.
Whereas we had done on-site surveys only a sample of classrooms for the previous studies, for this study we went on-site to measure attributes in every classroom, surveying a total of classrooms in 36 schools.
The preliminary statistical analyses replicated the structure of the models used in the previous studies.MBA Dictionary of Business Management Methods. This management dictionary contains a description and explanation of terms and methods.
