Myself and many others seem to find 21c too cold in winter and too hot in summer in some buildings. I think it's possibly due to radiant temperature: for example, the walls/roof/floor are hotter in summer so you need to cool the air down more to make up for that.
That said, Japan and some other places (Singapore!) take it to the extreme, and in a modern well insulated building, this is much less needed than it used to be. Maybe it's a hang-over from when wall insulation was terrible?
What I really don't understand is why, in London, the short distance commuter trains and buses are heated so warm in the winter. I'm only on the train for 10 minutes, why would I want to strip down!?
- edwcross 4y agoCould it be for driver comfort? I sometimes have the impression that buses have their temperature tuned for the driver, who's staying in the bus for hours and has everyone's safety at least partially related to their comfort. But I find it impossible to confirm this by asking the bus companies why their buses are set this way (e.g. when windows were closed during Covid at about 20°C).
- Fatnino 4y agoThe bus company doesn't set the temperature, the individual drivers do. That should explain everything.
- wink 4y agoOh yeah, I was soaked in the rain in Singapore once and took the bus home, I was basically sure I'd catch a cold, it was like stepping outside in the winter at home after taking a shower...
- andreareina 4y agoIn Singapore using a/c is still seen as a luxury so it's a selling point for the malls.
