Swiss architect Philippe Rahm is based in Paris, France, and is also a visiting lecturer at Princeton University's School of Architecture. He has received numerous awards and honors around the world for his distinctive brand of architecture -- often described as meteorological architecture -- and has designed everything from private homes to office buildings
In 2008, he designed apartments for the IBA (Internationale Bauausstellung, or International Building Exhibition) in Hamburg, Germany. They weren't just any apartments, though. They were convective apartments; as in, efficient in transferring heat using air currents. Not only are they oriented and built to route warmer air inside during the winter and cooler air inside during the summer, the apartments also have thermal zones within. Do we need every room to be the same temperature? For example, the warmest room inside is the bathroom at 71.6 degrees Fahrenheit (22 degrees Celsius), with the kitchen in the middle at 66 degrees F (19 degrees C) and the laundry room the coldest at 59 F (15 C).
