68 seems to be the highest most men can comfortably tolerate in the heating season, 70 if they are 65+ in age. It's a lot easier to warm yourself up than cool yourself down. When we program thermostats in commercial buildings, it's usually based around how many men are going to visit or work in that section of the building, and if they are going to be moving or sitting much of the day. Mens' internal body temp is generally higher than womens', so it's about finding the max temp the men won't bitch about that doesn't require women to wear blankets. It's a balance, I ask multiple people of both genders what they want it set at and pick the middle. Somebody will always be uncomfortable because there is a lot a variance between people, even of the same gender, so we're fighting biology. If there isn't a building maintenance guy, I'll usually find a woman in a management position to give the thermostat unlock code to because they know how cold the women feel, but nobody wants wants to work around sweaty men. Also, then it's corporates fault if the workers/customers are uncomfortable, not mine.
