Green Giant: Bank of America Tower, Manhattan

Channel Lumber is committed to the process of Green Building, and supporting LEED certification. Today we want to showcase a cutting edge Green skyscraper and highlight the latest Green design and amenity features.

In 2009, construction of the Bank of America Tower, in Manhattan, was completed. The building earned a LEED Platinum rating, the highest awarded. The rating is based on various environmental considerations. The design earns “points” for various energy saving and environmentally beneficial features. The cost of construction was One Billion USD. It is the fourth tallest building in Manhattan.

The design teams for the tower had one directive: to demonstrate that economic and environmental principles are compatible. When Green features added to the cost of construction, only those features which would pay for themselves within 5 years were included.

There were many other areas where the tower scored well including site selection (near public transportation), building form, and energy conservation.

The towers’ sloped form has two primary benefits. First, it allows more natural light to penetrate the building. 90% of workers have floor to ceiling windows which can be fully lit with natural light. Second, the sloped form allows for the efficient capture of rainwater, which can then be used in a variety of ways.

The Bank of America tower has an onsite natural gas power plant which generates 70% of the buildings electricity consumption, and 30% peak hour consumption. This eliminates electrical transmission losses which are significant on the city’s power grid.

The power plant makes ice at night which is used to cool the building in the day. Additionally the waterless urinals save up to 8 million gallons of water annually.

Channel Lumber has an extensive list of Green Projects and clients including the Aria Resort and Casino, Veer Towers, and the Portola Valley Town Center.

Channel Lumber Custom Lumber Shop: Corbels

In architecture a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket.

You see corbels throughout San Francisco, and they are very common on Victorian homes. Many corbels on homes are made of wood, and as such are prone to rot over time. The corbels often have unique shapes, and we copy the shape to replace rotten corbels, and match any remaining corbels on the building.

Custom corbels are made according to the following steps:

  1. Wood of the proper thickness is chosen, or wood is laminated to achieve the desired thickness.
  2. The wood is run on the joiner, cleaning up and making smooth surfaces.
  3. The wood is chopped to length with a miter saw, giving two clean working ends.
  4. The wood is then run through the thickness planer bringing to the proper dimension.
  5. The outline of the old corbel is then traced onto the wood.
  6. The outline is cut with a bandsaw.
  7. The new corbel is sanded and painted as needed.
