N2 - The two big fields of sustainability and Information and Communication Technology (ICT) are Green IT (how can we make ICT itself more sustainable) and Green by IT (how can we encourage sustainability by ICT). Taking a deeper look, software links these two areas: Regarding Green IT, there are a lot of solutions to build and use hardware in a more energyefficient way. But the debate how energy-intensive software might be is just beginning. In contrast, Green by IT is often software-based, e.g. by tools that help to optimize logistics and automate processes to save energy. But until now there are noconsiderations about the energy saving potential of softwareitself. Therefore, it is useful to take a closer look at what greensoftware and green software engineering are. In our paper, wewill describe a reference model for green and sustainablesoftware, as well as its engineering and also give somedefinitions. Though, we will just give a short introduction of themodel itself and, to distinguish our work from our previousresearch, zoom in on the sub model “Sustainability Criteria forSoftware Products”. Additionally, we describe a model tomeasure the energy efficiency of software and give an exampleof measuring results in our contribution. The next step is toclearly differentiate from other measurement models to positionour approach within other efforts of software’s energyconsumption.
