Operable Windows — International Style

This is the 1958 Logan Building at the corner of 5th and Union, and I like it. It was built with a complete air-conditioning system, which was an ultra-modern feature at the time. And no, your eyes do not deceive you: it has windows that open. Perhaps in 1958 people still had enough self-respect and/or common sense to not be willing to put up with a sealed building.

Today we need encouragement: green building rating programs such as LEED give points toward certification for operable windows.
