Greening of the City-County Building
- 39% reduction in electricity use
- 93% reduction in steam use
- 46% energy cost savings
The Indianapolis 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 Rocky Mountain Institute to lead a design charette with local energy engineers and business leaders. As a result, the City developed a request for energy proposal. Performance Services was selected to complete an energy audit and as a result was authorized to design and implement a "deep energy retrofit" guaranteed energy savings 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 utilizes a holistic approach and includes measurable results. The "Greening of the City-County Building initiative will serve to demonstrate leadership in sustainable practices, help to achieve the ENERGY STAR label, and become one of the most energy efficient public buildings in the nation.
