  Data centres are very fast growing structures with significant contribution
to the world's energy consumption. Reducing the energy consumption of data
centres is easier when the components that comprise a data centre and their
respective energy consumption are known. A complete model for a modular design
of a data centre and a technique for simulating each module's energy
consumption are presented. Detailed power consumption modelling for each
component as well as their interactions are the merits of this model. Unlike
existing research, the present modular simulation model can take different
design structures of data centres into account and provide us with hourly power
consumption profiles for each component. The impacts of environmental
parameters such as temperature and humidity are also investigated and
incorporated into the model. The flexibility, scalability, comprehensiveness
and modularity of this model provides researchers and designers with a powerful
tool for energy analysis, management and planning of data centres with
different designs and locations.
