I must admit that I lost the original reference for the claim, but almost certain it was LifeHacker, so it is notable enough.
The claim is that 72-73 degrees Fahrenheit (or about 22-23 Celsius) is THE optimal temperature range for office productivity, with above 74 and below 71 measurably negatively impacting productivity.
Are there unambiguous and uncontested study results proving that there's a measurable (beyond statistical noise) effect?
