The Sustainability pavilion — one of three theme pavilions at Expo 2020 and a permanent structure — was designed by Grimshaw Architects as a net-zero energy building and drag construction practices into the future.
Nearly 5,000 solar panels cover the pavilion roof and solar “trees,” which rotate with the arc of the sun for maximum light exposure. Another “tree” will harvest water by condensing air humidity, an innovative irrigation system will water the gardens, and wastewater will be recycled. The pavilion is partly buried, keeping it cooler than its surroundings.
Visitor Saeed Al Kaabi, 25, from the UAE, told CNN, “I feel proud that the Expo is here, the world is here now: 192 countries in my country.”
“Clean energy is a good thing, the world is changing,” he added. “The central dome is the most impressive part of the pavilion.”
