A Passive Solar Housing Complex In Paris  

Inhabitat has an article on a green building development in France - Passive Solar Parisian Housing Complex Adapts to its Natural Environs.

This organic housing project in Paris creates a buffer between the dense city streets and the preserved green spaces beyond. Designed by Jakob + Macfarlane, the Harold Housing Project features a smart set of solutions that overcame tight restrictions on building on the reclaimed site. The project was carefully planned to respect the landscape while capturing the sun and adding to the local greenscape. Public and private areas blend seamlessly as the city appears to melt away beneath the preserved trees and breezeways. ...

Each building is composed of a series of terraced layers that rise upward, providing shade for the apartments below. The first floor is reserved for businesses and handicap-accessible apartments, and the floors above reinforce the greenscape with a ribbon of green roof that rises over the exterior walkways.
