YTA.

I’m a health and safety manager in Aus and the codes suggest between 20-26 for offices. The problem is that even if something is reading at the suggested temp, unless you’ve got top tier tech, it’s not taking into consideration all factors, and cannot account for individual needs and acclimatisation.

I’m good at around 17-18 C, because I run hot. I keep a fan on my desk, I wear cooler clothes etc. but that doesn’t always cut it. The sun enters the window behind my desk at certain times of the day. Airflow might be less if there’s less traffic through the office than normal, and some days it’s just so damn humid.

Someone who runs cold can put more clothes on. They can use small heaters that only heat their desk area. They can use heated scarves or jackets. They can have warm drinks, hop up and move around to warm up etc.

For those who run hot, there are less options. I’m sure you don’t want her getting more naked… and it’s even harder if they run hot for any medical reasons, e.g. medications, menopause etc.

In an indoor environment in the temperatures you’re talking about, heat is more risk than cold.
