Temperatures are set based on formulas that aimed to optimize employees' thermal comfort, a neutral condition of the body when it doesn't have to shiver to produce heat because it's too cold or sweat because it's too hot. It's based on four environmental factors: air temperature, radiant temperature, air velocity and humidity. And two personal factors: clothing and metabolic rate, the amount of energy required by the body to function.

The problem, according to a study in Nature Climate Change on Monday, is that metabolic rates can vary widely across humans based on a number of factors -- size, weight, age, fitness level and the type of work being done -- and today's standards are based on the assumption that every worker is, you guessed it, a man.

Or if you want to be really specific, a 40-year-old, 154-pound man.

Kingma and van Marken Lictenbelt's work builds on research out of Japan which found that the neutral temperature for Japanese women was 77.36 degrees (Fahrenheit) while it was 71.78 for European and North American males.

5.58 degrees is a significant difference. Is it better for half the people in the office to be sweaty than half the people in the office to be chilly?

    What are daltons? Are they derived from SI units?

    FYI: atomic mass unit [wikipedia.org]:

    The unified atomic mass unit (symbol: u) or dalton (symbol: Da) is the standard unit that is used for indicating mass on an atomic or molecular scale (atomic mass). One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is equivalent to 1 g/mol. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 1.660538921(73)e−27 kg. The CIPM has categorised it as a non-SI unit accepted for use with the SI, and whose value in SI units must be obtained experimentally.
