Résumé

Simulation tools are widely used to assess the energy consumption of a building. During the modeling process, some choices have to be made by the simulation tool user, such as the division of the building into thermal zones. The aim of this study is to assess the influence of building zoning on the results of the dynamic thermal simulation, including, or not including, airflow and thermal transfers between zones. With this purpose in mind, several different building zonings (49-zone to 11-zone models) are applied to the same office building. The impact of merging the floors is analyzed by considering different roof and floor insulations and the impact of merging the orientations is studied by using different glazed surface ratio and climates. The results of the dynamic thermal simulations are compared in terms of energy demand (heating and cooling) and computational and setup times.
