i could accept the premise of a maximum summer temperature in principle, but not as low as 27. on a day where it's 27 and cloudy, i would often need to put on pants, or a long-sleeved shirt. 27 is moderate to cool, it's not warm. 

further, such legislation is inherently misogynist, as it directs temperature regulations towards cooler temperatures preferred by men, and even by heavyset or obese men.

in order for a maximum temperature enshrined in legislation and enforced by law to be inclusive of women and healthy people, it should be something closer to 40 degrees. a legislated maximum temperature should be 35 degrees celsius, minimum.
