老鹰环保 (Eagles GoGreen!)组织发言人诺曼·法舍特(Norman Vossschulte)说，绿色环保“现在已成为我们工作人员DNA的一部分”。

法舍特表示，球队的体育场每年需要大约10兆瓦电力，其中4兆瓦由体育场自身提供。其余均来自绿色能源，大部分为风能。

通过使用节能LED灯，同时为供热和空调系统装上计时器，耗电量自2004年以来已减少了一半。

2013年，老鹰队的努力得到了回报：该体育场被授予“绿色建筑认证”(LEED certification)，获得美国绿色商业理事会(Green Business Council) 的绿色建筑批准印章。LEED一词代表 “能源与环境设计先导”(Leadership in Energy and Environmental Design，LEED) 。该体育场获得银级认证（白金为最高等级；详情参见右侧注解）。

什么是LEED?

获得“绿色认证” 的建筑需按高环保标准建造。该方案采用计分法。积分越多，认证级别越高：

－ 铂金：80+分
－ 黄金：60-79分
－ 银色：50-59分
－ 通过认证：40-49分

费城老鹰队一马当先，同时还有其他几支球队走在绿化美国职业体育场馆的前列：

Being green “is part of our staff’s DNA now,” said Eagles GoGreen! spokesman Norman Vossschulte.

It takes about 10 megawatts to power the team’s stadium for a year, and the stadium produces 4 megawatts of its own energy. The rest comes from green energy, mostly wind, Vossschulte said.

Electricity consumption has been cut in half since 2004 by using energy-saving LED lights and putting heat and air conditioning systems on timers.

In 2013, the Eagles’ green efforts were rewarded when the stadium earned “LEED certification,” the U.S. Green Business Council’s seal of approval for green buildings. The term stands for Leadership in Energy and Environmental Design (LEED). The stadium earned Silver certification (Platinum is the highest; see sidebar).

What is LEED?
A building that is “LEED-certified” means it was built meeting high environmental standards. The program uses a point system. The more points, the higher the level of certification:
– Platinum: 80+ points
– Gold: 60-79 points
– Silver: 50-59 points
– Certified: 40-49 points

The Philadelphia Eagles led the way, but here are a few other pioneers in the greening of U.S. professional sports arenas:

The Golden 1 Center in Sacramento, California, will be the first sports venue in North America to be powered 100 percent by solar energy when it opens in fall 2016. Its design uses natural cooling to reduce energy use, helping it to earn LEED Gold certification.

When Nationals Park opened in Washington in 2008, it made history by becoming the nation’s first major sports facility to achieve LEED certification. Steel with 95 percent recycled content was used in its construction. And it has a green roof — 585 square meters of it.

Completed in 2000, AT&T Park was the first Major League Baseball stadium to install solar panels and to receive LEED Silver certification. It achieved LEED Gold status in 2015. The solar panels provide enough power to supply 5,200 homes across San Francisco.

Some 35 percent of the concrete used to construct the CenturyLink came from the stadium it replaced in 2002: the demolished Kingdome Stadium. Nearly 100 percent of waste is diverted, and 19 million liters of biodiesel fuel were produced in 2014 from recycled cooking oil.

MetLife Stadium in East Rutherford, New Jersey, is more than twice as large as the old stadium that it replaced in 2010, but it has reduced energy use by 30 percent through energy-efficient practices. In 2012 some 1,350 solar panels were installed.

The Consol Center was the first National Hockey League arena awarded LEED Gold certification in North America. Builders used recycled materials in its construction in 2010 and diverted waste from landfills.
