I think it's time to look at getting a new (hopefully "cheap") laptop. Could you charge it to a grant or start-up funds?
I'm in the UK and have my own window that opens and my own radiator with knob. Right this minute I am feeling better about my situation (I'm annoyed at some British attitude I got earlier today).
Very few grants and/or start up funds in my field.
I have two windows but none in this building actually open.
I second the idea of getting a kicka$$ machine at home. Have the IT guys load all the software you will need, and any/all data files you have.
We have thermostats in our offices.. curiously they don't seem to be attached to anything. They are like the "Close Elevator" buttons.. it just makes us feel in control.
The personal funds are a bit tied up at the moment for... big events and purchases over the next few months.
I'm sure there's a hidden camera so that the physical plant guys can watch you adjust the thermostat and secretly laugh at you.
