ATC Environmental Monitoring -
RELATIVE HUMIDITY
|
The American Society of Heating, Refrigeration, and Air-Conditioning
Engineers (ASHRAE) recommends indoor air be tempered to within the
following parameters:
| RELATIVE HUMIDITY | WINTER TEMPERATURE | SUMMER TEMPERATURE |
| 30% | 68.5 - 76 °F | 74 - 80 °F |
| 40% | 68.5 - 75.5 °F | 73.5 - 79.5 °F |
| 50% | 68.5 - 74.5 °F | 73 - 79 °F |
| 60% | 68 - 74 °F | 72.5 - 78 °F |
Low humidity has been associated with dry skin and eyes and with
respiratory irritation.
