Lifetime exergy consumption of enterprise servers
Several studies have recently examined the environmental impact of enterprise computing in terms of server and cooling power consumption, but such an approach fails to capture the lifecycle impacts associated with raw material extraction, manufacturing, transportation and end-of-life. This paper details the development of a lifetime exergy consumption model that captures these impacts. Use of the model is demonstrated via case studies examining the effects of variance in transportation and cooling strategies. The results show the importance of taking a lifecycle view in evaluating sustainability of computer systems.
