Treasure Hunt Map

During an Energy Treasure Hunt, teams walk around a facility looking for quick ways to save energy. Those quick fixes can add up to big savings. Hundreds of organizations have used Energy Treasure Hunts to reduce their facilities’ energy use by up to 15 percent. Are you and your crew ready to find the treasure buried within your facilities?
