The concept of harmonic thermal conductances is very well suited for modelling dynamic thermal behaviour under periodic boundary conditions. A method for implementing such a model in simulation software is proposed and compared to simplified methods currently employed in international norms and standards. The practicality and efficiency of the harmonic approach is demonstrated using an appropriate simulation software package (“AnTherm”), which allows the three-dimensional, time-dependant visualisation of simulation results. In conclusion, arguments for specific future developments are presented, including the potential for model translation into 4D-enabled virtual environments.
The paper "Practical implementation of a harmonic conductance model
in thermal simulation software" has been presented lately during the 9th Nordic Symposium on Building Physics held in Tampere (Finland) from 29th May till 2nd June 2011.
