Abstract(s)
Data Centers are growing steadily worldwide and they are expected to continue on growing up to
53% in 2020. Due to this growth the energy efficiency in this type of building is essential. There are
methodologies to measure this efficiency; one example is PUE (Power Usage Effectiveness). The
unit suggested for measuring efficiency at the design stage would be the EUED (Energy Usage
Efficiency Design) with this will be used data to use "free cooling" and adiabatic system in some
cases, a comparison will be made only considering the equipment in the worst situation. It also uses
the study of enthalpy utilization as a new methodology to obtain the results. By doing so, differences
were found, between cities than 1.21% of SĆ£o Paulo in relation to Curitiba and 10.61% of Rio de
Janeiro in relation to Curitiba. The indices obtained by applying the EUED index were 1.245 kW.kW-
1 for Curitiba, 1.260 kW.kW-1 for SĆ£o Paulo and 1.377 kW.kW-1 for Rio de Janeiro, respectively, giving
a difference of 16.86% for Curitiba of 16.19% for SĆ£o Paulo and 10.31% for Rio de Janeiro in relation
to PUE COA (Power Usage Effectiveness Constant Outdoor Air).
