Air... We all need air... Some people have air for free, they open the window and there is air. Some people like unconditional air, some people like conditioned air. And thus humanity (?) created AC. And the summer comes and we turn on the AC and we see It's Good. And humanity created more efficient AC units, and we thought that was Good. Better. More is Better. Mo' cold during the summer, mo' better.

Until it's unbearably cold.
We walk into a room, and there it is: door handles are cold to the touch, people want to huddle together but it's a business meeting not a party, the smart and not forgetful ones (the lucky ones) remembered to bring their jackets, coats, long sleeve anything.

AC is definitely broken.

Either we don't know how to control our HVAC systems or we can't control it. I think it's the latter: cannot control it. Modern technology (even buildings that were built this millenium!) has not fixed the problem. It takes years to be able to comply with a setpoint! It's broken!
