With this handbook, you can learn how to develop an Urban Living Lab, based on the lessons learned, research and practical experiences from the UNaLab project. The tips included here are given by Living Lab experts who successfully have set up a Living Lab in their own community. You will learn about the questions which need to be asked, the roles of the people working in a Living Lab and the obstacles which you need to watch out for. At the end of the handbook, you will find an interactive tool to guide you through your Living Lab journey. In this handbook, the focus is on Urban Living Labs – meaning Living Labs operating within an urban setting (in a city).
