A comparative modeling of an experimental single-zone building with Bond Graphs and TRNSYS
Journal of Energy, Environment, and Economics
In this work, after a brief presentation of state of the art on building thermal modelling, we show the interest of having an open and flexible environment to develop and test new models. The Bond Graphs technique, used to represent the building dynamic thermal behavior over a single zone building structure, is compared with the building analysis tool TRNSYS and with experimental data. An evaluation of indoor temperature and heating loads was carried out in order to check our Bond Graphs and TRNSYS models. Validation procedure has shown very good agreement between measured data and both Bond Graphs and TRNSYS simulations.
