Occupant Comfort and Psychrometrics

Presented by Jesse Fisher (WB Engineers+Consultants)


A comfortable environment is critical to the productivity, well-being, and happiness of the space occupants of any indoor built environment.  This presentation will discuss the many factors affecting thermal comfort ranging from the routinely discussed space temperature and humidity to the less frequent questions about space air velocity and occupant clothing levels. Additional topics include common performance gaps between expected and actual comfort levels, the likely causes of these gaps, as well as potential improvements.


At the end of the discussion participants will be able to:

  • define thermal comfort goals for individual project spaces based on space type and occupancy.

  • diagnose occupant comfort problems and  identify and the most likely culprits.

  • plot space conditions on a psychrometric chart and determine related properties of the space.

  • analyze the contributory effects of part load HVAC system operation on occupant comfort.

  • recommend modifications to occupant behavior in order to improve occupant comfort.
