Increased air flow around the full
perimeter of the window enables highly
efficient natural ventilation while
greatly reducing draughts as fresh air
is drawn in the bottom of the window
while warm, stale air is expelled via the
top, creating full air circulation within
a room.
Penoyre & Prasad worked from the

break-out spaces for the Anna Freud
Centre.
