Empire State Building to cut energy use by 40 percent
New York's tallest building is to cut its energy consumption by 40 percent using efficiency and behavioural measures.
The iconic feature of the New York skyline will benefit from a retrofit which will reduce its energy bills by $4.4 million (£3 million) a year.
Supported by the Clinton Climate Initiative in the enterprise, the building's owners will upgrade the landmark's 6,500 windows.
"In this distressed economic climate, there is a tremendous opportunity for cities and building owners to retrofit existing buildings to save money and save energy," said former president Bill Clinton.
Insulation will be added behind radiators to keep heat in and cold out.
Smart lighting which is only switched on when a room is occupied will reduce electricity use and new heating and air conditioning systems will be installed.
However, as well as using technology to reduce energy use and carbon emissions, the building's upgrade will try to coax users to take personal responsibility for their own energy consumption.
Tenants will have access to an online system that will allow them to monitor their energy use and provide tips on how to reduce power spend.
About 79 percent of New York City's emissions come from buildings and, according to the government's Energy Star programme, half of the city's planned CO2 reductions will come from improving buildings.http://tinyurl.com/d4b553
