Empire State Building cuts energy use 20% - May. 7, 2012

By Steve Hargreaves (CNN) The Empire State Building is on an energy diet.The hulking building, a symbol of American power and, to some, excess, has cut its energy use by 20%.And thats just due to changes to the buildings exterior. Once retrofits are made to tenant spaces on the inside, the second tallest building in Manhattan will be nearly 40% more efficient.

The retrofits will cost $20 million once theyre complete, and are expected to save the owners $4.4 million in annual energy costs.”After one year, we have proven that investing in energy efficiency gives building owners a dollars-and-cents advantage,” said Dave Myers, a president at Johnson Controls, which conducted the retrofit.

The changes to the Empire State include:

  • Filling the existing windows with an energy saving gas and adding an additional plastic pane.
  • Upgrading the buildings cooling system.
  • Using computerized “smart” energy management technology that can adjust temperatures floor by floor.
  • Provide tenants with detailed energy use in their space.
  • Automatically shut off lights in unused areas.
