le cube orange, jakob + macfarlane, lyon, france, energy efficient building, perforated facade,

The building serves as the headquarters for the Cardinal Group, a real estate development firm, as well as the Design Showroom RBC. The intention of the project was to combine a showroom dedicated to the world of design objects inside the architecture of a fantastic building and create an experience along the banks of the river. Orange was chosen as the color for the building as a reference to the industrial color commonly used in harbors. A giant void in the building is created by subtracting three ‘conic’ volumes, which generate interesting spaces, daylighting and views of the river.

Most of the building is covered in a perforated facade that acts as a shade screen minimizing direct sun on the interior. Energy efficiency is maximized with this screen and all of the offices enjoy natural daylighting. A geothermal heat pump with heat recovery provides energy efficient heating and cooling, making use of the relatively constant temperatures of the nearby river. Then, a photovoltaic system on the roof provides 10% of the building’s electricity needs.
