Effect of the occupant and the inside faces coating of a multi-alveolar structure on the unsteady thermal behavior of a bi-zone building

The aim of this work is to study the unsteady thermal behavior of a bi-zone building exposed to sunshine under clear sky conditions. The walls in South and West frontages are equipped with a multi-alveolar structure with a variable insulation depending on the heat flow direction. The structure has blades which are inclined relative to the horizontal direction. The results show the effects of the optical properties of the inner surfaces of the alveolar structure, the position of the alveolar structure with regard to the stone layer and the occupant on the unsteady thermal behavior of the bi-zone building.
