Abstract: This paper proposes an exergy-based approach to evaluate the sustainability of different Information Technology (IT) systems. We suggest the need for metrics that include a second-law component as well as a life-cycle view in evaluating sustainability. Having identified such a metric, we demonstrate applicability of the framework for a sample IT system. We conclude by reflecting upon additional research needs and challenges associated with widespread implementation of such a framework.

Keywords: exergy; information technology; sustainability; sustainable design; available energy; second law; sustainable IT systems.
