My Dad was a Mechanical Engineer so he was ‘in charge’ of all the ‘mechanicals’ for a number of huge buildings, mostly full of women doing secretarial-like work. He had the same problems with the heating and a/c comfort levels.
He put out a memo that read: “Everyone is to bring a sweater to work. Hang it on the back of your chair. If you are COLD, put the sweater ON. If you get too HOT, take the sweater OFF!”
It sort-of worked, LOL!
I knew an project engineer for Mobil Oil during the Carter gas crisis. The federally mandated temperature was too chilly for the office ladies to type even with sweaters. So the engineer broke into the controls and recalibrated the thermostat.
