Abstract

Modeling of the thermal behavior of buildings needs effective strategies of analysis and tools. This is particularly true when conduction of heat through walls and/or slabs has to be properly taken into account. This article is concerned with a new modeling strategy for solving the transient heat conduction equation in a finite medium (with extensive background application to the different elements of a building structure). The developed approach is based on the Bond Graph technique, a graphical modeling language which is particularly suitable to the treatment of problems involving energy transfer. With this model, two typical transient heat conduction situations (corresponding to the most practical cases in building envelope, such as heat transfer through vertical walls, roofs and slabs), are considered. The related validation procedure consists of comparing the obtained results with available analytical solutions. The Bond Graph technique is then used to model the dynamic thermal behavior over a single zone building structure. Finally, results are compared with a set of experimental data.
