The room temperature was too warm and I was told the thermostat was not to be changed. There was no concern however with opening the door. This is a bit silly since we were wasting all the heating energy. Also it was not possible on rainy days and was noisier. Perhaps need to face computers all in the same direction.
Lab tends to get too warm in the afternoon.
New sound absorbing tiles work too well and often it is difficult to hear students questions especially from the back row. The room felt very cramped and uncomfortable epecially at night when it was raining. It would be nice to have an area to store backpacks and coats. The accoustics in 241 are terrible. Students on one side of the classroom can't hear students on other side.
