Hainan Energy Trading Building features sky gardens arranged diagonally across every four floors, connecting to the open ground floor and central atrium for natural ventilation and a comfortable micro climate for the workspace. The green areas, including the balcony plants, sky gardens, and overall landscaping, are almost equivalent to the site area. Structural bracing allows the sky gardens to reach four floors high column-free. High energy-efficient double skin façade provides sufficient daylight and a magnificent view of the coast.
