Are you hot or cold in one of our branches?
Send an email to fcc.fod [at] mcgill.ca with the date and exact location of the problem (i.e. Cold draft in the Humanities and Social Sciences Library, February 13 at 2pm, 2nd floor McLennan, Sherbrooke Street side).
We're working on creating a solution and the more details we have, the better.
Thanks for your help.
