Looking at Terraserver to orient N/S and DisZip's map of BCV....I think I butchered his name there.....none of the rooms face directly South. I think your best bets are X03-07 odd(SW) and x25-31 odd(SE). X39-51 odd also face the Southwest but I think a just little more obliquely. X33 almost faces East but is on the South side of the building so...
Hope that helps.
