We should go for something like Dartford FC's stadium - totally undermine the greenies from the start: http://en.wikipedia.org/wiki/Princes_Park,_Dartford
"Construction work began on 14 November 2005. Designed by Alexander Sedgley architects, the stadium has a capacity of 4,100 (642 seated), and has been described as one of the most ecologically sound ever built.[1] The pitch level is sunk two meters below the external ground level to reduce noise and light pollution. It is estimated to have cost around £7 million. The stadium was opened on 11 November 2006 when Dartford FC, who had been without a home ground in the borough since 1992, beat Horsham YMCA 4-2 in an Isthmian League Division One South league fixture, in front of a capacity 4,097 crowd.[2]
The environmental aspects of the stadium include - The stadium roof has a sedum roof blanket, a living roof that provides a natural air filtration system. solar panelson the roof serve the community changing areas and public toilets hot water storage cylinders.

Rain water is collected in the two large ponds at the north end of the stadium grounds. Underfloor heating on both levels of the clubhouse. Low energy lighting. Increased fabric insulation to give the clubhouse better thermal retention and efficiency. Condensing boilers to provide a more energy efficient system. Also excavated earth was reused for landscaping the external courtyard areas around the stadium.[2]"
