To maintain the proper temperature and maximize the heating and air conditioning system, windows should be kept closed (unless opened temporarily when weather permits). Under no circumstances are windows to be used for entering or leaving a residence hall. Open windows are not to be used to broadcast music to the community outside the residence hall. No items may be displayed on room windows in order to maintain an attractive appearance of the building. Screens are not to be removed from windows. Under no circumstances are the fasteners to be broken, bent or removed.
