Demonstration projects and sustainable housing

The significance of demonstration projects as a so called second generation steering instrument is examined by the use of case studies. Because of the complicated structure of the built environment, it is frequently difficult to obtain good results on sustainable development projects. In The Netherlands, the Dutch government have used a range of new steering instruments which have cleverly enabled innovation to take place within a market economy. This imaginative governmental process uses covenants, network management and above all, demonstration projects to assess the feasibility of innovation. The authors describe the process and consider examples from energy efficient and sustainable housing, highlighting the importance of clear targets.
