Entwicklung und Anwendung von Bewertungsgrundlagen für ressourceneffiziente Software unter Berücksichtigung bestehender Methodik - Abschlussbericht


Gröger, Jens; Köhler, Andreas; Naumann, Stefan; Filler, Andreas; Guldner, Achim; Kern, Eva; Hilty, Lorenz; Maksimov, Yuliyan (2018). Entwicklung und Anwendung von Bewertungsgrundlagen für ressourceneffiziente Software unter Berücksichtigung bestehender Methodik - Abschlussbericht. Dessau-Roßlau: Umweltbundesamt.

Abstract

In this research project, the evaluation basis for resource-efficient software is being researched. To this end, an impact model is being developed that shows the link between the use of software and the energy consumption of hardware as well as the use of hardware. By classifying software products into local applications, remote data storage and processing applications as well as server services it is shown that energy and resources consumption may take place at different locations.
Based on existing findings on resource-saving software development and software design, an evaluation methodology assigning software properties to the impact areas of resource efficiency, potential useful life of hardware and autonomy of use is being developed. Furthermore, a catalogue of criteria with a total of 25 criteria and 76 indicators for assessing the environmental impact of software products is being drawn up.
Several case studies (two word processing programs, three internet browsers, three content management systems, three database systems) show that the evaluation method and the criteria developed are applicable in practice, and reveal relevant differences of software products with the same functionality. As a result, the recommendation to develop a "Blue Angel" eco-label for resource-efficient software is being formulated. In order to facilitate the application of the evaluation method, three supplementary modules are also being developed, i.e. a reference system for carrying out measurements on office software, a software for evaluating hardware utilization and energy consumption, and a recording tool for obtaining the evaluation criteria. The conclusions will provide recommendations for the application of the evaluation methodology as controlling tool for product policy. Furthermore, they will identify further-going research needs.
