Not to mention the solar and photovoltaic panels and wind turbines which allows The Pixel to produce its own energy.
Shanghai Tower, China
Also well-known as the second tallest building in the world, Shanghai Tower gets a place in this list with a reduction in water consumption and energy usage by 40 and 21 percent respectively. Using wind turbines and a gas cogeneration system it produces about 54,000 kWh energy per year. The carbon footprint of the building down to 34,000 metric tons a day because of the design methodology and new technology used.
The Edge, Netherlands
What's the best thing about The Edge? It produces more energy than it uses! Solar panels, led panels and water propulsion loop sums down to a very eco-friendly structure. The Edge also boasts a unique temperature regulation system. Adding to that, it's considered to be a smart building which can track individuals moving within.
