On Earth Day, 16 West Michigan buildings are among the honorees at the second annual Energy Summit.

The Battle of the Buildings is a year-long competition trying to reduce energy consumption. Participants included 157 buildings in nine different categories.

In Grand Rapids alone there are six award winners, led by the Meanwhile Bar and the Pyramid Scheme with energy reductions around 20 percent.

Overall, the competitors reduced energy use by nearly 16,000 metric tons. That is the equivalent of taking 3,300 cars off the road.

Friday's Energy Summit was the only one of its kind in Michigan, with a goal of learning from each other, said Cheri Holman of the US Green Building Council.

"Lots of businesses are interested in reducing their energy," Holman said, "and we just wanted to be a place for them to learn what new things they can do since technology is rapidly changing."

This year the number of buildings competing in the contest nearly tripled.
