Performance contracts may be one way to revolutionize how we manage our buildings in Michigan. By leveraging private sector expertise, which is able to guarantee savings, we should be able to make our buildings more efficient without spending additional taxpayer funds. Reducing costs in the Dept. of Corrections and other depts. is what reinventing Michigan is all about.
