Abstract
In order to answer the need for energy efficiency, building, whatever it is (industrial, commercial, domestic), still electrifies more and more. Hence many equipment, in particular power electronic or actuators are introduced and produce conducted and radiated electromagnetic disturbances. They propagate via cabling and protection devices which have been sized for 50Hz and not for high frequencies generated by the equipment. This constitutes the EMC problematic for building.The proposed modeling methodology is to evaluate an electrical equivalent circuit for each installation’s component. Access to lumped parameters of each component is one of the highlights of this method, allowing the other components association (couplings). The generated models are implemented in a circuit software such as Spice, enabling the resolution and the association of other electrical components.The modeling of the components, mainly the grounding circuit, allows the simulation of different configurations. The analysis of several configurations should help the elaboration of design rules to make today buildings more efficient.
