Abstract
In this work, a simplified graphical modeling tool, which in some extent can be considered in halfway between detailed
physical and Data driven dynamic models, has been developed. This model is based on Bond Graphs approach. This
approach has the potential to display explicitly the nature of power in a building system, such as a phenomenon of
storage, processing and dissipating energy such as Heating, Ventilation and Air-Conditioning (HVAC) systems. In this
paper, thermal behavior of an elementary referential building configured with two similar adjacent spaces has been
modeled in order to assess the performance of the combined Radiant Heating and Cooling (RHC) systems. The thermal
simulation of the building has been performed by using the Bond Graphs modeling approach, where both temperatures
and heat flux annual profiles, according to the radiative heat exchange, have been calculated. Comparison with TRNSYS
software results has also been made. It was found that the RHC system is able to meet energy demand of the building
insuring a good thermal comfort level.
