Project Description
The City-County Building is a 50-year old downtown landmark constructed at a time when energy efficiency and green technology wasn’t a top priority. Given the cost of maintaining the building, the Mayor of Indianapolis, Office of Sustainability, and the Indianapolis Marion County Building Authority worked with the nationally recognized Rocky Mountain Institute to lead a design charrette with local business leaders and engineers. Following a request for guaranteed energy savings proposal, Performance Services was selected to create and implement a “deep energy retrofit” design and project at no cost to taxpayers.
Under the direction of Ron Reinking, the Building Authority has overseen a number of energy-related improvements over the years, but nothing as comprehensive as this project, which used an integrated approach and includes measurable results. The “Greening of the City-County Building” initiative serves to demonstrate City leadership in sustainable practices. The building achieved the ENERGY STAR® label in October 2012.
