Cairo's ultra-green mixed-use development will be topped with flowing solar canopy

Paris-based Vincent Callebaut Architecture has come up with a plan for a mixed-use complex located in Cairo that combines vegetation and structure to communicate Egypt's inclination toward progressive architecture, designboom reports. The proposal's main purpose is to raise awareness of sustainable architecture designed to combat global warming. 

The roof is solar, and shades green rooftop terraces and sky villas. This conserves energy otherwise needed for cooling, as do the solar panels and heating tubes on the roof.

Nine stories of housing contain 1,000 residential units, all within a series of rectangular volumes situated around a central boulevard, according to designboom. Four stories of underground parking, a supermarket, office space, and three levels of retail space are also included in the complex.

The retail areas will be fronted by a transparent curtain wall punctuated by green walls to indicate the main entrances towards the shopping mall. The roof of the whole development is set as a big community garden comprised of an area of orchards, infinity swimming pools, and sports facilities. 

The scheme includes eight specific sustainability features:
1. Windcatchers
2. A passive geothermal cooling system
3. Solar photovoltaic cells, which cover all the solar roof and the west and east facades
4. Solar heater tubes, located on the roof above each core
5. Wind turbines, integrated along the axial spine at both ends of the promenade
6. Roof food gardens cover the whole complex, improving the thermal inertia of the roof
7. Living walls
8. The use of recyclable and/or recycled furniture.
