We needed to understand conditions in the library reading room where staff complained of cold temperatures. Unit heater problems were considered a likely cause along with a high infiltration rate.
Installed a temperature data logger in the zone and measured heat temperatures coming out of ceiling cassette with the infrared thermometer. Temperatures were cooler than the rest of the library on cold days, but unit heater was heating appropriately.
Temperature problems were linked to drafty windows. Advanced Energy Panels were installed in the windows at low cost to limit infiltration and as a result, complaints were reduced.
Placement of temperature data loggers in a representative area was a minor challenge but suitable locations were agreed upon with library staff.
