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.
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.
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.
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.
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
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.
quote: 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.
