We all know that people’s wellbeing and performance is affected by various environmental conditions, but we haven’t known to what extent. The Whole Life Performance Plus project (WLP+) explores this in three very different buildings.
The report shares the results of two case studies where more than a year’s worth of data was collected through continuous physical monitoring, surveys, and human performance testing.
The human performance results were perhaps the most interesting. Using validated tests (numerical, proofreading, processing speed/attention) as a proxy for performance, the study showed that performance was negatively impacted by high temperatures (particularly over 26C/88F), low humidity (particularly below 40%), and high CO2 concentration (particularly above 1000 ppm).
Interestingly, the link between perceived productivity and the the workplace environment were statistically stronger than the links between measured productivity.
The report concluded that indoor environments need to be examined more granularly if human performance is to be optimized.
