Mayo Clinic hit its 20 percent energy savings goal two years early, according to an article on the Post-Bulletin website.
The estimated energy savings at the Rochester, Minn., facility is $26 million since 2011.
After they set the goal in 2011, Mayo began improving the efficiency of the buildings’ existing systems. Fifty campus buildings were recommissioned. Much of the work there involved reprogramming the control systems.
The cost of recommissioning was about $1,500,000. Energy efficiency rebates totaled more than $888,000.
