Colloquially, room temperature is the range of temperatures that people prefer for indoor settings, at which the air feels neither hot nor cold when wearing typical indoor clothing. The range is typically between 15 °C (59 °F) and 25 °C (77 °F) and various methods of climate control are often employed to maintain this thermal comfort level. In certain fields, like science and engineering, and within a particular context, "room temperature" may have an agreed upon value for temperature.
The American Heritage Dictionary of the English Language identifies room temperature as around 24 to 25 °C (75 to 77 °F).
Owing to variations in humidity and likely clothing, recommendations for summer and winter may vary; a suggested typical range for summer is 23 °C (73 °F) to 25.5 °C (78 °F), with that for winter being 20 °C (68 °F) to 23.5 °C (74 °F)., although by other considerations the maximum should be below 24 °C (75 °F) – and for sick building syndrome avoidance, below 22 °C (72 °F).
According to the West Midlands Public Health Observatory (UK), an adequate level of wintertime warmth is 21 °C (70 °F) for a living room, and a minimum of 18 °C (64 °F) for other occupied rooms, giving 24 °C (75 °F) as a maximum comfortable room temperature for sedentary adults.
Ambient versus room temperatureEdit
Room temperature implies a temperature inside a temperature-controlled building. Ambient temperature simply means "the temperature of the surroundings" and will be the same as room temperature indoors.
