Its the same in my uni. the lecture theatres smell of poo, the labs are either frozen or like a sauna and usally stink of wee, barf and poo.
We blame the first years (the great unwashed). Glad uni aint open through the summer or then they would really reeeek!!!! <img src="http://www.theunholytrinity.org/cracks_smileys/contrib/sarge/MissileSmilie_anim.gif" alt="" />
