On Sunday, the Carolina Panthers and Denver Broncos will face-off for Super Bowl 50 at Levi's Stadium - the first LEED Gold certified football stadium and one of the most energy efficient stadiums in the world. The $1.2 billion home of the San Francisco 49ers was the first stadium to open in the U.S. to achieve LEED Gold Status certification from the U.S. Green Building Council.

To become certified LEED, projects have to accumulate points by meeting certain conditions. Levi's earned 44 points (only 39 are required for Gold) through sustainable site developments, water savings, efficient energy, and most importantly: reclaimed wood.
