What is PUE & L.E.E.D?
PUE, or Power Usage Effectiveness is the standard measure of how a data centre utilises its power. The PUE figure of a datacentre is the ratio of the total power used by the facility (cooling, heating, lighting etc) divided by the power usage of the equipment located in the facility.
L.E.E.D, or Leadership in Energy and Environmental Design, is a rating system specifically aimed at the design, construction and operation of high performance buildings - in this case, data centres. L.E.E.D focuses on a number of categories, such as sustainability, energy usage, water efficiency and the environmental impact of the resources used in construction.
