Measurement

Measuring Power ConsumptionThere have been tremendous advances made over the last few years in the power, performance and functionality of ICT equipment in the office environment and servers and communications equipment used for more intensive operations. These advances have clearly led to the development of a richer set of functionality for the end user, whether they are static office-based or mobile workers.

Whilst the manufacturers of ICT equipment (servers, laptops, printers and communications equipment) are designing in energy efficiency, whether that is as a consequence of legislation or competitive advantage, there can be a wide discrepancy between the ‘faceplate’ power rating and the power that is actually consumed in the day to day use of end-user devices. This is similar to the problem faced with A category fridges actually performing at a D or lower category due to how a consumer uses the fridge eg amount of space, how often the door is left open etc.

It is thus important to be able to measure power consumption whilst an electronic device is being used and designers of office equipment must now consider carefully how best to guide and assist users in utilizing available equipment whilst they work.
