Exploiting object-oriented modelling for scalable-detail studies on control for energy efficiency

Simulation is widely used to assess and/or improve the energy efficiency of both existing and new buildings. Such an analysis has to account for heterogeneous phenomena efficiently, to manage components in a modular manner, and (which is seldom addressed in a structured way) to scale the detail level in all or part of the model, based on the particular simulation goal. In this manuscript, a proposal is formulated on how to structure a Modelica library so as to satisfy such a need.
