I believe these are public housing for the elderly. They were built on slum-clearance land during Hyde Park's urban renewal period (late 50s, early 60s). They indeed have windows in the rear, facing the courtyard.
However, there are a similar set of private residences in Kenwood which have no windows on the exterior. They do feature an atrium in the center, but you wouldn't know from outside. Check it out in street view: http://maps.google.com/maps?hl=en&q=Chicago+5018+S.+Dorchester&um=1&ie=UTF-8&sa=N&tab=wl
