eco?

It is very hot today.
Our university has eco-system that room temperature is set 28℃. I think that it is a little wrong, because room is much too hot to study. At least, the first basement rooms should not be used. We feel stuffy there.
Other departments have eco-style, but...is it good ? I do not think so. I think  the excessive system is not good.

I like summer but　Ｉ do not like the rainy season.Now I want season to set in winter early.
