The purpose of this thesis was to measure energy consumption of workstations and external devices in School of Business and Information Technology and search for possible solutions to reduce electricity consumption. The commissionaire for the thesis was Oulu University of Applied Sciences School of Business and Information Management unit. The reason for the study is that School of Business and Information Management has a environmental plan which is based on ISO standard 14001 and this thesis is part of that by trying to discover possible new solutions to reduce electricity consumption. ISO (International Organization for Standardization) standard 14000-group consists of such as environmental auditions, product life cycle evaluations and various eco-labelled standards. Present ISO 14001-standard was approved in November 2004. Purpose of this thesis was to help the school in this plan and seek information and solutions and/or alternative options which would bring down the energy consumption of our schools computers and external devices as low as possible and at the same time think all the solutions in aspect of ”environmental friendliness”. Foundations for the thesis have been acquired from various articles and books concerning electricity consumption, recycling, production of electric components and literature about Green IT in general. Research methods consist mainly of data gathered using energy meter by using an ETECH PM300 energy meter device in between the electrical socket and measured device. Main results of this thesis have been energy consumption of individual workstations and energy consumption of variable external devices. Results and conclusions were not so black and white. Finding the right solution might be extremely difficult since new hardware setup might not be so energy efficient and vice versa. What comes to further measures central air conditioning, lighting and servers should be evaluated.
