Official Recommendations

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) makes a primary recommendation regarding comfortable temperatures in an office environment: for those employees wearing what is considered an average amount of clothing, the environment neither needs to feel too cold or too warm. OSHO guidelines will take this a bit further to say that temperature controls should be in the range of 68-76 degrees F and humidity control in the range of 20%-60%. It also states that office temperature and humidity conditions are a matter of human comfort rather than hazards that could cause death or serious physical harm.

Sometimes your temperature has to do with body chemistry and what you wear. Men are generally warmer than women, but they also tend to wear pants and long sleeves to work.

  • Colder temperatures encourage productivity.
    The U.S. Department of Energy reviewed over 24 studies around the world regarding temperatures and productivity. In 2006, they published results and found that, on average, worker productivity decreased once office temperatures hit 75 degrees Fahrenheit.
  • Comfortable temperatures may increase morale.
    Comfortable employees are happy employees. While an absolute ideal temperature remains elusive, as an employee (both men and women) consider wearing layers, so that you can adjust for personal comfort. Try to find an average upon which everyone can agree.
  • Program the thermostat to save money.
    If you are cold or too warm, avoid your first instinct to crank the temperature in either direction. Minor adjustments of a degree or two will prompt the system to turn on and can create a sufficient change. Extreme changes in settings will cause the system to work overtime, thus
