It will make a real difference if you're at the gym or in a very crowded place though.

Wouldn't the AC system adapt to the increased heat production from the extra people and maintain the temperature at 27'C?

The AC's temperature sensors won't feel your microclimate or body temperature. I'm all for 27°C in the general case, but yeah I'd prefer a few degrees lower in the gym or in a dense crowd.
