Resumo: 	Abstract Data Centers are growing steadily worldwide, and they are expected to continue growing up to 53% in 2020. Energy efficiency, in high power consumption, is a key venue. There are methodologies to measure this efficiency, one example is using the PUE (Power Usage Effectiveness) index. In this paper is proposed a new index for measuring efficiency at the design stage, the EUED (Energy Usage Effectiveness Design). This index allows to evaluate systems using “free cooling” and adiabatic system. A comparison is performed considering the equipment in the worst situation. The thermodynamics parameter enthalpy is used to calculate the results. This new methodology allows to determine differences between the cities of São Paulo and Curitiba (1.21%) and between Rio de Janeiro and Curitiba (10.61%). The values for the EUED index were 1.245 kW/kW for Curitiba, 1.260 kW/kW for São Paulo and 1.377 kW/kW for Rio de Janeiro, respectively, reaching a difference of 16.86% for Curitiba, 16.19% for São Paulo and 10.31% for Rio de Janeiro in relation to PUE COA (Power Usage Effectiveness Constant Outdoor Air). The advantage of the EUED is that it works with the 8,760 hours in the design phase, using psychometric elements to determine when to use free cooling and evaporative system, and more importantly varying the COP according to environmental characteristics.
