Housing the new headquarters of the financial giant Bank of America, the green featuresimplemented in this design quickly allowed it to rack up all the points it needed to garner its LEED Platinum rating. Quite uncommon for a tower of its size, the new building employs a system for rainwatercatchement and reuse, greywater recycling, energy efficient building systems, and high performance glass which maximizes day-lighting and minimizes solar heat gain and loss. However, it’s the state-of-the-art, onsite 4.6-megawatt cogeneration plant that really gets the ‘oohs’ and ‘ahhs’ going. The advanced system provides a clean and efficient power source for the building’senergyrequirements, significantly reducing its reliance on the NYC grid. The system also perfectly compliments an incredible cooling system that produces and stores ice during off-peak hours, and then uses the ice phase transition to help cool the building during peak load. Another remarkable innovation is the air purification system – not only is the air entering the building purified to a high standard, but the air exhausted is also cleaned, effectively making the tower a giant air filter for Midtown Manhattan. With an area of over 2 million square feet, this level of green technology in one building is nothing short of remarkable.
But it’s not all about intrinsic mechanical systems or energy and waterconservation, the tower itself was constructed using a concrete manufactured with slag, a byproduct of blast furnaces. The mixture is a concoction of 55% cement and 45% slag, where the use of slag cement minimized any residual damage to the environment by decreasing the amount of cement needed and in turn lowering the amount of carbon dioxide output that would have occurred through traditional cement manufacturing. Moreover, the building was built by and large with recycled and recyclable materials, and all the materials were sourced locally to reduce carbon costs and to support the local economy.

It\\\'s great to laud this green skyscraper! But keep in mind that One Bryant Park received its LEED Platinum certification back in May: http://www.tishmanconstruction.com/files/LEEDPlatinum05-20.pdf The building was also covered in depth in ArchitectureWeek by contributing editor Michael J. Crosbie back in early July: http://www.architectureweek.com/2010/0707/environment_1-1.html Still more photos of the building can be seen at Archiplanet: http://www.archiplanet.org/wiki/Bank_of_America_Tower_at_One_Bryant_Park%2C_New_York%2C_New_York

I have the stellar photo of 1 Bryant Park, taken on August 27th, 2009.
One Bryant Park IS the first skyscraper to win LEED Platinum for new construction. The Joe Serna Jr. Cal/EPA Headqrtrs Bldg. in Sacramento, CA won LEED Platinum for Existing Buildings.
Great little article! I was pleased to discover your website which seems quite fascinating. However I was a little put off by what I believe to be an error in the article. I take issue with the factual accuracy of the following statement, "Today we're thrilled to announce that the green tower has just achieved LEED Platinum certification, making it the world's first office tower to reach the USGBC's highest rating!" I'm not sure exactly how you are defining office tower, but the Joe Serna Jr. Cal/EPA Headqrtrs Bldg. in Sacramento, CA achieved a LEED Platinum certification almost 7 years ago. (can be verified at this website: http://www.usgbc.org/LEED/Project/CertifiedProjectList.aspx) Granted it is only a 25 story office tower, but it is an office tower with a Platinum certification. Cheers.
Its is all good news, but what is the Bank of America or the owner of the building benefiting from this? What are there reason, why do they want to do this. However i would love for them to try and promote this by having other organization on on board.
yes, but who did the Engineering?
This really is an interesting building and the photos do an amazing job of capturing it! After looking at these pictures I really want to go see it!
