Stuttgart’s Internal Contracting links different independent parts of the city authority to enable quick and flexible investment decisions. Its operational scope is energy improvements within the municipal building stock. The scheme is exclusively operated as an internal process wherein the underlying revolving fund functions as an intermediate buffer for cash flows. The fund is embedded within Stuttgart’s regular accounting system as a part of the city’s general budget.

 Every financing aspect (investment,(saved) energy costs, payback) remains under the municipality’s control.

The Infinite Solutions project is co-financed by the European Commission under the IEE Programme
