| Abstract: | Results from the analytical and inter-program validation of a building thermal model (CBS-MASS) are presented. Within the analytical validation, the analytical solutions of the steady-state and the transient heat transfer through the exterior walls of an intermediate floor room are compared with the predictions of the computer program. The analysis of the transient process concerns the response of the room air temperature and the inside surface temperature of walls subjected to step-function change of outdoor conditions. Good agreement between the analytical solutions and the simulation results indicates that the basic heat transfer processes are well simulated by the computer program. The inter-program validation deals with the comparison between the estimations of the space thermal loads in one office space provided by the CBS-MASS program against the predictions of two well-known programs used in the thermal analysis of buildings: BLAST and TARP. The results show good agreement between the predictions of these programs. Hence, the analytical and inter-program validation indicates that the CBS-MASS program provides good estimation of the thermal behavior of buildings. |
