NEW YORK CITY — The Empire State Building is slated to undergo a green renovation process that will reduce the building’s energy use and greenhouse gas emissions by up to 38 percent. Changes include a 6,500 window light retrofit, the introduction of radiator insulation, improved tenant lighting, daylighting and plug upgrades, air handler replacements, a chiller plant retrofit, a whole-building control system upgrade, ventilation control upgrades and new Web-based tenant energy management systems. Upon completion, the building should achieve an ENERGY STAR score of 90, and it will pursue LEED Gold certification. Jones Lang Salle will be managing the renovation. The initial cost of the renovation is anticipated to be $20 million with a resulting $4.4 million in annual energy savings once the project is complete.
