ASHRAE standard 55, Thermal Environmental Conditions for Human Occupancy, notes that for thermal comfort purposes, the indoor temperature should range from approximately 67ºF to 82°F (19.4ºC to 27.8ºC), and systems designed to control humidity must be able to maintain a dew-point temperature of 16.8°C (62.2°F). ASHRAE standard 62.1, Ventilation and Acceptable Indoor Air Quality, recommends that relative humidity in occupied spaces be controlled to less than 65% to reduce the likelihood of conditions that can lead to microbial growth. Determine the minimum allowable indoor temperature that will ensure a humidity control system designed according to ASHRAE standard 55 will also satisfy the humidity requirements of standard 62.1
