Employing Virtual Power Analytics and Linked Data for Enterprise IT Energy Informatics

ABSTRACT

The paper provides a solution to an organization's challenge for reducing its ecological footprint. We develop a framework for visualizing information concerning power consumption of IT devices in real-time using power metering approaches and leverage semantic web technologies to weave information that is dispersed across different data sources, ranging from an organization's asset databases to excel spreadsheets to the data available on manufacturer's websites. Visualizing the aforementioned information and bringing it together in one application can help organizations in understanding and adapting their energy consumption behavior in order to better support environmentally sustainable practices. The purpose of this project, from a power analytics standpoint, is twofold: (1) it aims to provide users with insight into their device's current power consumption without leaving a footprint on their machine, and (2) to analyze if one method gives more accurate results than others. We performed analysis using Microsoft Joulemeter and power estimation using software design methodologies (with numbers from smart meters as our benchmark).
