ASHRAE standard 55, Thermal Environmental Conditions for Human Occupancy, notes
that for thermal comfort purposes, the indoor temperature should range from
approximately 67°F to 82°F (19.4°C to 27.8°C), 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
