To go green, Ernst & Young LLP has enlisted the help of JAS consulting, Philips Lightolier Energy Services and lighting design firm One Lux Studio, to retrofit 32 floors of its US headquarters in New York City with LED lighting solutions from Philips.

Ernst & Young LLP's Times Square office lighting system is heavily utilized by its more than 5,500 employees. With its traditional lighting system, the approximately 650,000 Useable Square Foot, Class A office space consumed roughly 6.2 million kWh annually.

In contrast, the new LED lighting will not only save the company close to $1 M per year in energy and maintenance costs, it also will cut its lighting energy use by roughly 2.9 million kWh per year and reduce its CO2 emissions by approximately 2 million pounds annually.

In total, the new lighting system will reduce Ernst & Young LLP's lighting-related energy and maintenance costs by more than 50% a year and its annual lighting energy use by 54%. It has also improved the facility's quality of light.
