In this presentation, I will explore how sound, healthy business models for open source projects can look like, with a focus on environmental informatics. I will do so by first analysing which elements of open source projects exist that can, potentially, generate turnover, and will then estimate the relevance of these different elements, for different types of projects, taking into account costs and other efforts. This will be illustrated by several cases, including the openLCA project where I am involved in myself. Result of this is an overview of types of business models of successful open source projects, that each deploy means that fit best to their specific situation. Result is further that these business models frequently do not follow a common pattern; finding these requires often a wider view of analysis, and more creativity, and under certain circumstances, business models are likely to fail. These critical circumstances will be highlighted, as to be carefully avoided when tailoring a new project. I will conclude with a tentative outlook on further development of the identified project types.

Visualising the Power Quality of Websites Naumann, Stefan; Gresk, Sascha; Schäfer, Kerstin Moeller, Andreas; Page, Bernd; Schreiber, Martin Visualizing the quality of a product or a service regarding its environmental impact is an important step to foster sustainability. Since Internet and Information Technology have an increasing consumption of power, it is interesting to visualize if a Website is hosted with green electricity. We developed a prototypical Firefox extension, which depictures this power quality. The service bases on a database where several providers are stored who offer hosting with green electricity.

The main goal of the project is the development of information, manager and economic tools supporting an integrated waste management system of the Czech Republic in compliance with the EU waste legislation, the Thematic Strategy on the prevention and recycling of waste and further connected EU standards. The paper focuses on analysis of information tools support of this project.

This affects components regarding a certain aspect (e.g. material flow analysis or simulation runs) as well as software-related infrastructure components e.g. GUI, logging or persistence. Within the EMPORER project, supported by the German Federal Ministry of Research and Technology (BMBF), an extendible and component based software platform is developed. Based on this software platform there will be some components and applications developed for the fields of material flow management and simulation as a proof of concept. Thus, the objective of this development is to offer an easy to use tool kit and framework which can seamlessly be extended by components with a close-to-the-problem functionality. To bring forward further development and distribution, the platform will be made available as an open source software framework enabling further methods and components to be complemented by third parties. This paper describes the basic architecture and the fundamental extension possibilities of the software platform which is based on Microsoft’s .NET.
