The main project's goal is to develop a guideline for sustainable public construction projects. The guideline will be presented on special website and provides detailed description of initial phases of the public construction projects (with emphasis on participatory design and sustainability) and will be based on thorough analysis of needs and problems of the cities. The validity of the procedure will be verified during the pilot testing in two towns. The outcome of these projects is the functional specifics of the building. Publication and dissemination activities provide towns and experts with complex knowledge on the public construction contracts and support interdisciplinary cooperation of different disciplines during the construction process of sustainable public buildings.
