it's nice, very well designed and modern, but in my opinion it's a little bit too cold to be a residential unit, would be perfect for an office tho.
here is a pretty innovative building in san francisco:

it is said to be the most environmental friendly building in the world.
Buildings used to be designed with the climate in mind with big opening windows to the exterior; shading and bris de soliel to the south; shallow working areas to maximize exposure to natural light. Mix the desire to build a green, efficient building with post 9/11 security and you have Thom Mayne's new San Francisco Federal Building.
