Summary: | 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. This
paper represents the developed models of the two transient heat conduction
problems corresponding to the most practical cases in building envelope, such
as the heat transfer through vertical walls, roofs and slabs. The validation
procedure consists of comparing the results obtained with this model with
analytical solution. It has shown very good agreement between measured data
and Bond Graphs model simulation. The Bond Graphs technique is then used to
model the building dynamic thermal behavior over a single zone building
structure and compared with a set of experimental data. An evaluation of
indoor temperature was carried out in order to check our Bond Graphs model.
