- KonferenzbeitragA Master Program on Engineering Energy-Aware Software(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Lago, PatriciaSoftware-intensive systems support most if not all aspects of modern society and in all industrial sectors. Because of software’ pervasiveness and crucial role, its energy consumption and impact on sustainability cannot be neglected anymore. As computing resources are necessary to run software, and as software runs more and more globally (e.g. in data centers and by cloud providers), time has come to engineer energy-aware software. This means educating current professionals and future generations with the appropriate skills and competencies. This paper describes the design of our program in “Software Engineering and Green IT” within our Computer Science curriculum and extending our Master Track in Software Engineering. We also introduce four types of modules that we defined to design our program, and for each type discuss the underlying rationale, learning objectives, risks and related mitigations, with the idea to offer them as building blocks for other educators.
- KonferenzbeitragA Maturity Model for Green ICT: The Case of the SURF Green ICT Maturity Model(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Hankel , Albert; Oud, Lisa; Saan, Maiko; Lago, PatriciaThis paper discusses the development and evaluation of a maturity model for Green ICT. We describe how the model was developed with the input of a number of Green ICT experts before it was released to the general public. The model consists of three domains with attributes on Green ICT that encompass both Greening of ICT as well as Greening by ICT. The quality of the model and its accuracy to capture the full scope of Green ICT has been evaluated through an online survey. We evaluated the quality of the model on relevancy of attributes, whether the attributes were well defined and whether the domains were complete. Twenty participants contributed meaningfully. Two attributes were considered to be irrelevant and six new attributes were suggested. With these results the quality of the maturity model can be improved. Our next step is to test the usefulness of the model by seeing how it is used in practice. We hope this paper inspires more work on testing the quality and usefulness of models and frameworks on Green ICT.
- KonferenzbeitragArchitecting for Sustainability(EnviroInfo 2022, 2022) Lago, Patricia; Greefhorst, Danny; Woods, EoinSustainability is becoming an increasingly important topic. Information Technology (IT) is an important factor for sustainability; it consumes a substantial, and growing, part of the world supply of energy, but it can also enable significant insights and improvements related to sustainability. These factors need to be taken into account in the design of IT systems, meaning that we need to architect for sustainability. This paper provides insights into the experience and beliefs of IT practitioners and researchers into current and desired practices of architecting for sustainability. It reports on the results of three workshop sessions with practitioners and researchers, providing insight into the state of research and practice.
- KonferenzbeitragEnergy Efficiency in Cloud Software Architectures(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Procaccianti, Giuseppe; Bevini, Stefano; Lago, PatriciaCloud-based software is often considered as providing a greener, more energy-efficient solution. At the same time, it introduces more complexity and demands for new investments in cloud services, technologies, and competencies for migration, maintenance, and evolution of the underlying software architectures. To understand better the implications of cloud software architectures on energy efficiency, in this paper we present the preliminary results of a systematic literature review that investigates what kind of software architectures for cloud service provisioning allow to achieve energy-efficient solutions.

- KonferenzbeitragThe Green Practitioner: A Decision-Making Tool for Green ICT(EnviroInfo & ICT4S, Conference Proceedings, 2015) Lundfall, Karl; Grosso, Paola; Lago, Patricia; Procaccianti, GiuseppeThe environmental impact of ICT represents an increasing concern for modern society. Despite that, we still witness a lack of awareness from the ICT industry regarding their carbon footprint. In particular, practitioners lack knowledge and tools to perform informed decision-making in the area of Green ICT. Moreover, best practices for Green ICT are usually conceived and applied in-house. This prevents them from being generalized and shared with the community. In this paper, we present a web-based tool that tackles both needs: on one hand, the tool enables practitioners (i.e. agents) to browse a number of Green ICT solutions and calculate their estimated impact if applied to their organization, through customized parameters. On the other hand, the tool also provides a creation interface for contributors who want to generalize and share their own Green ICT practices. In addition, we foresee that the data generated by the usage of the tool will provide useful insights and trends regarding the adoption of Green ICT and its effectiveness on reducing CO2 emissions.
