The 50th Superbowl at Levi’s Stadium will be a net-zero energy game

The Superbowl and sustainable aren't two words you would normally find in a sentence, but the San Francisco 49ers and <a href="http://www.hntb.com/" target="_blank">HNTB Corporation</a> have done their level best to change that with the 68,500-seat Levi's Stadium. Solar-powered and crowned with a green roof, the first new NFL stadium to achieve <a href="http://inhabitat.com/tag/leed-gold" target="_blank">LEED Gold</a> certification produces sufficient power to ensure game days will be net-zero energy.

Levi's Stadium has capacity for 68,500 fans.

A green roof provides insulation and stormwater runoff management.

The solar-powered stadium is net-zero energy on game days.

Connectivity with the Bay area was an important consideration, so the stadium is linked to a major walking and biking trail and various forms of public transportation.

The stadium is used year round for a variety of events.

The design was inspired by the Roman Amphitheater.

This is the first new pro football stadium in the NFL to achieve LEED Gold certification.
