Jeanne Gang, whose innovative residential skyscraper, Aqua, was the subject of a cover story in the Reader, has a clever new building called Windermere West planned for Hyde Park (h/t Gapers Block). Many of the south-facing windows are tilted 71 degrees, so that when the sun is low in the winter more light gets in but the rooms are shaded when the sun is high in the summer. More light in winter and less in summer means simple energy savings. It’s a bit radical for such an architecturally homogenous area–“I would go to that building only to get directions away from it,” said one friend and long-time resident–but it appeals to the geek in me. Or, more accurately, to me, being a geek.

Speaking of Gang, you might enjoy this Q&A with her on Aqua.
