Empire State Building retrofit project could cut energy costs by $4.4 million per year

New York City has put some greener updates in its tallest skyscraper, the Empire State Building, in the form of refurbished windows that will reduce solar heat gain and decrease the building's energy costs.

These updated windows were installed as part of the Empire State Building retrofit project, which is funded by the Clinton Climate Initiative, the Rocky Mountain Institute, Jones Lang LaSalle and Johnson Controls. The entire project costs $20 million, and aims to cut CO2 emissions by 105,000 metric tons over the next 15 years. It is also expected to decrease energy consumption by 38 percent, and reduce energy costs by $4.4 million per year. 

The project has recently completed the refurbishing of the windows, which will decrease the building's energy costs by $400,000 per year alone. These 6,514 triple-glazed insulated windows panels, which contained 96 percent of the original glass and frames, will also cut solar heat gain by more than 50 percent.

But this project doesn't stop at making the windows more thermally efficient. In addition, the plan is to add insulation to radiators to avoid heat loss, introduce improved lighting, replace air handling units with variable frequency drive fans, improve controllability and efficiency by reusing chiller shells and "replacing the guts," upgrade building control system to improve HVAC operation, upgrade ventilation control system and introduce web-based power systems available to each individual tenant for better management of power usage.

With these updates, the Empire State Building could become LEED (Leadership in Energy and Environmental Design) Gold certified, which means it meets green criteria according to the U.S. Green Building Council

The project is expected to be completed by 2013, and upon completion, will become a model for other greener updates throughout New York City as well as other major cities.

Case in point, my coworkers tell me not to worry about leaving the lights or A/C on because we don't pay for it. Well I explained to them that energy costs for all would be reduced if people stopped thinking that way. It seemed that they followed my logic, but it wasn't until I gave them some sob story about how the ice caps are melting and the cute penguins babies won't have a home anymore did they take a bit of heed.

Your coworkers are certainly idiots, even if they didn't care about the environment, they'd care about saving their company some money, since maybe that extra saved money would save someone's job or make enough budget to hire one more person.
Me, personally, I hate to see anything go to waste, so I turn it off if i'm not using it.

First of all, we don't pay for the electricity directly. As a company. This is because we lease a building from an adjacent company and the power is 'on the house' so to speak.

My point is not that people are idiots (which my co-workers are not) but that people don't think very much about these things and it is only when you show them an Al Gore apocolypse movie that they start to think. And unfortunately they usually want to legislate their thoughts. And that IS idiotic, but unfortunately it is the norm now and I guess I can't blame them.

So anyway I try to do my part to get people to think about these things in a rational way.
