Short Bio

Sonja Klingert has been with the University of Mannheim since January 2010 as a researcher and local manager for the European research project (STREP) FIT4Green, All4Green and DC4Cities. She has been chair of the international workshop E2DC since 2012. Before joining University of Mannheim, she was coordinator of the European research project (STREP) GridEcon at the International University in Germany. Prior to this she worked as a researcher for the Wuppertal Institute for Climate, Environment and Energy, Germany.

Her research interest is in eco-aware data centres (including demand response approaches, metrics), green business models, eco-aware contracts like GreenSLA and GreenSDA as well as eco-aware requirements engineering processes. Among others, she is chair of the international workshop series Energy Efficient Data Centres. S. Klingert received her M.S. degree (“Diplom”) in Economics from the University of Karlsruhe in 1996.

Current Research Project

The goal of DC4Cities, the European project called "An environmentally sustainable data centre for Smart Cities", is to optimize urban energy consumption in data centers to become more environmentally friendly. Namely, data centres in Smart Cities shall be enabled to shape their energy consumption in a way that they can follow to a great degree (up to 80%)  the pattern of availability of renewable energy resources like sun and wind.

More and more often, Smart Cities need their data centers to be located inside the same region. Therefore, optimizing energy consumption of these data without degrading its environment, is a must. Based on this premise, DC4Cities links the  management of IT loads to the accounting of available renewable energy, enabling data centers to adapt their power consumption depending on of the amount of renewable energy available.

The GreenIT group within the Software Engineering Group among others is responsible for the requirements engineering process (work package lead), parts of the communication between the Smart City Energy Management Authority and the data centre and the organization of dissemination events like the 3rd International Workshop on Energy Efficient Data Centres E2DC 2014 as well as E2DC 2015.

The EU-FP7 project All4Green was launched in November 2011. Its goal is to establish a collaboration framework within the eco-system of energy provider, data centre and end-user.

The EU-FP7 project FIT4Green aims at contributing to ICT energy reducing efforts by creating an energy-aware layer of plug-ins for data centre automation frameworks. More details...
