2nd International Workshop on Green and Sustainable Software

– 20th May 2013 –

Workshop in conjunction with ICSE 2013

Motivation and Goals

ICT accounts for approximately 2% of world CO2 emissions, a figure equivalent to aviation, according to Gartner estimates. In the remaining 98% software counts for both operationalizing the private sector in doing its business and the public sector in supporting the society, as well as delivering end-user applications that permeate personal life of individuals and families.

Software can contribute to decrease power consumption (i.e. become greener) in at least two ways. First, by being more energy efficient, hence using fewer resources and causing fewer CO2 emissions. Second, by making its processes more sustainable, i.e. decreasing the emissions of governments, companies and individuals.

To this end, enterprise software must be rethought to address sustainability issues and support innovative business models and processes. The special theme of the second edition of GREENS is “Leveraging energy efficiency to software users.” GREENS 2013 brings together software engineering researchers and practitioners to discuss the state-of-the-art and state-of-the-practice in green software, as well as research challenges, novel ideas, methods, experiences, and tools to support the engineering of sustainable and energy efficient software systems.

GREENS 2013 seeks contributions addressing, but not limited to, the following topics related to greener software engineering:

  • Requirements engineering, architecting and design methods for green software
  • Best practices to increase energy efficiency and sustainability (including software and process improvement)
  • Green architectural knowledge, green design patterns
  • Monitoring, verification and validation of green software
  • Creating user awareness about energy consumption of software applications and services
  • Views/visualizations of software/users energy performance
  • Tools supporting green decision making and development
  • Green metrics, key indicators for energy efficiency, green labels
  • Quality & risk assessments, tradeoff analyses between energy efficiency, sustainability and traditional quality requirements
  • Business models for green software (incl. software-as-a-service and cloud computing)
  • Green adaptation of software-intensive systems
  • Greening data management
  • Challenges for a green software industry
  • Return on investments and economic aspects of green software development
  • Case studies and industry experience reports
  • Decision making and incentives to invest in greener software

 – Keynote –

We are happy to have Prof. Dr. Schahram Dustdar from Technical University Vienna as our distinguished keynote speaker.

Schahram Dustdar is Full Professor of Computer Science (Informatics) with a focus on Internet Technologies heading the Distributed Systems Group. From 1999 – 2007 he worked as the co-founder and chief scientist of Caramba Labs Software AG (CarambaLabs.com) in Vienna (acquired by Engineering NetWorld AG), a venture capital co-funded software company focused on software for collaborative processes in teams. Caramba Labs was nominated for several (international and national) awards. Since 2009 he is an ACM Distinguished Scientist. Recipient of the IBM Faculty Award 2012. Since 2011 he is director of the Pacific Controls Cloud Computing Lab (PC3L), a joint research lab between Pacific Controls and the Distributed Systems Group (DSG) of the TU Vienna are working together to push the frontiers of cloud computing, pervasive computing, data management and Internet of Things.
