Room temperature, colloquially, denotes the range of air temperatures most people find comfortable indoors while dressed in typical clothing. Comfortable temperatures can be extended beyond this range depending on humidity , air circulation , and other factors.
This is the energy produced from a unit skin surface area of an average person seated at rest. [1] ANSI/ASHRAE Standard 55 provides a table of metabolic rate of different continuous activities. These values are valid for an average adult with surface skin area of 1.8 m 2 (19.6 ft 2). The standard reminds the users that they should use their own ...
It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 g (1.1 oz) per cubic metre when the air is saturated at 30 °C (86 °F). [8] [9] Air is a gas, and its volume varies with pressure and temperature, per Boyles law. Absolute humidity is defined as water mass per volume of air ...

The heat index explains why humidity makes a difference. Have you ever checked the temperature and noticed that it "feels" several degrees hotter? The heat index explains why humidity makes a ...
The recommended level of indoor humidity is in the range of 30–60% in air conditioned buildings, [34] [35] but new standards such as the adaptive model allow lower and higher humidity, depending on the other factors involved in thermal comfort. Recently, the effects of low relative humidity and high air velocity were tested on humans after ...
T w = Natural wet-bulb temperature (combined with dry-bulb temperature indicates humidity) T g = Globe thermometer temperature (measured with a globe thermometer, also known as a black globe thermometer) T d = Dry-bulb temperature (actual air temperature) Temperatures may be in either Celsius or Fahrenheit; Indoors the following formula is used:
