During the winter, window interior temperatures usually fall below indoor air temperature, causing thermal discomfort due to radiant temperature asymmetry, low operative temperature, and downdraughts
Larsson, Moshfegh (2002) examined different cases of window installation and came to a conclusion that the window bay width affects the downdraught
in two different ways: by deflection of the flow and loss of the momentum.
