Masdar City, which was prepared for the UAE World Expo, is known as a green Utopia in the desert. Its architecture is novel and most of it is made of environmental protection materials. The self-circulating wind tower in the center is a major feature. The breathing solar energy building is the same as the famous pineapple building. Because it is still in the construction period, it feels a little dusty on the site. It is estimated that it will be very good after completion.
