10 futuristic green corporate buildings

Some of these buildings exist only on paper (or rather a computer hard drive), but this is a list of 10 large office buildings “that are not only bold, beautiful and futuristic, but ‘green’ too.”

I’m especially impressed by the “Cactus Building,” a new government building in Doha, Qatar. As the name suggests, it “draws its inspiration from the ability of cacti thriving in a desert. The energy efficient structure features sunshade panels that open and close according to the sun’s intensity, as well as a botanic dome adding to its green rating.”
