The Empire State Building: Brighter & Greener

البريد الإلكترونى طباعة
Yes, as of 2011, The Empire State Building, one of the world’s largest buildings has achieved the distinction of becoming the largest buyer of green renewable wind power. The Empire State Building will be using more than 100 million kWh of wind energy in the coming couple of years approximately. It will be totally – 100% – wind-powered from now on! This is not the only feather in the lofty Empire State Building’s green cap. Already the tall building has executed the refurbishment of fitting of all its – some 6500 or so – windows with a unique type of insulating glass for power savings. Some $13.2 million very well spent in boosting the green credentials.

Reduction in deadly footprint
By purchasing 100 million kWh of wind energy from Green Mountain Energy Company’s wind farms, The Empire State Building has beat by far any other commercial customer in purchasing renewable energy. Think of how much less carbon emission there will be because of this. It has been calculated to be equivalent to the amount of carbon dioxide emitted by whole of New York State houses in one full week – some 100 million pounds of carbon!

Getting a better edge
The Empire State Building’s supervisor, Malkin Holdings, is upbeat about another offshoot of getting the wind-energy to power the building. Clean renewable wind energy from the wind farms and power savings from the insulated window glasses have given them an extra edge in getting tenants with better credit and credentials, he claims.

Setting better standards
Mr. Malkin expects that these innovative changes to using more and more renewable energy sources can set an example to be followed by other landlords to become energy efficient and make the entire city cleaner, more energy smart, and greener. Seeing the benefits doubled – no tripled – at The Empire State Building’s savings and revenue can be a great encouragement for others to follow suit.

Topping the list
With the latest power purchase, The Empire State Building has shot up the list of Environment Protection Agency’s League Table of 100% Green Power Purchasers. There are people who are not impressed by this achievement or certification, and criticize that it is more effervescence rather than having any concrete effect on investments in green energy. But nobody can deny that it is a great step in the right direction by The Empire State Building.
