Building New: The Time Go Green
Now, as “they” say, “the greenest building is the one that has yet to be built.” What a nice thought, although slightly unrealistic. Construction in the United States has slowed in response to the economic recession. However, China, where despite the economic crisis, engineers are completing four more tower blocks every day – almost all fitted with air conditioning, heating, lighting and lifts that will run on coal-powered electricity.
As opposed to the United States, China is in the middle of the greatest building boom in human history. Six of the world's ten tallest buildings completed last year were in China. Each new building that is erected imposes a negative effect on the environment which is why incorporating Green Building Practices into these structures is the only way to alleviate some of the irreparable damage.
The Pearl River Tower, now being built in Guangzhou, China is being promoted as the most energy efficient skyscraper ever built. With four wind turbines, solar panels, sun-shields, smart lighting, water-cooled ceilings and state-of-the-art insulation, the tower is designed to use half the energy of most buildings of its size and set a new global benchmark for self-sufficiency among the planet's high rises.
Engineers say the tower could even be enhanced to create surplus electricity, with micro-turbines that could sell electricity back to the grid at night. Unfortunately, the local power firm opposed this proposal as a caution to protect its monopoly over energy generation. With this approach to the construction of new structures, cities all over the world can lessen the impact they have on the environment. The new buildings can be utilized as an energy source, as oppose to the leader in energy consumption.
Although the incorporation of Green Building Practices costs more upfront, it will take approximately five years to earn back the cost and thus begin saving on energy consumption. The future of buildings seemed bleak, but now with Green Building Practices and examples around the world of successful implementation, maybe there is hope after all.
