How to write the notice that the company will not turn on the air conditioner in autumn?

It can be considered from the aspects of environmental protection and health.

The most comfortable wind blows in through the window. If it's not too hot, please turn off the air conditioner and change the water like a fish in a fish tank.

In order to have a comfortable and ventilated environment for everyone, the company leaders have held many meetings to discuss and decide that no air conditioner will be turned on this autumn, and no one can violate it, giving everyone a working atmosphere close to nature.

It's autumn now, so it's getting cold in advance, in order to reduce carbon and save every kilowatt hour.
