I'm in the process of analyzing time not meeting adaptive comfort (ASHRAE 55) in the Adaptive Comfort Summary. I realize this is during occupied hours, but my values seem to be above the hours occupied?
For example a zone is occupied by 33 students (100%) from 7am-2pm, and the teacher (3%) stays until 4:30pm. The total amount of school days in a year is 179. How does OpenStudio calculate the total occupied hours?
The school day for all occupants is 9 hours. If I'm not missing anything, I should be arriving at 1611 occupied hours in the year. However, my time not meeting the adaptive comfort model (80%) is 1934, and 2477 for the 90% limit. This would be well above the occupied hours.
With added shading as part of our interventions, we were able to get the 80% limit to 1819, which is 114 uncomfortable hours reduced.
What would a possible interpretation of these values? Having been to the actual room it truly is quite uncomfortable and our model is at an acceptable NMBE of less than 5%. I'm curious how to explain these results.
