To reduce energy consumption in buildings, passive solutions have been developed greatly like increasing the insulation of exterior walls. One way to improve the energy efficiency of buildings is to design multi-functional facades that capture the energy available locally: the principle of hybrid envelopes, able to both isolate, protect, but also capture, store, transport energy. Our study is about a solar collector made up mainly of a photovoltaic cell (receiving surface) and a wall of storage. The goal of this work is to heat naturally the habitat using a system which ensures initially the cooling of PV-cell. In this paper a simulation model have been made for a BIPV trombe wall. Computational fluid dynamic (CFD) has been applied to predict air temperature and velocity in the room during December 10th. The simulations for three-dimensional model BIPV trombe wall is carried out using the climatic data of Tlemcen, Algeria. The temperature variations at certain nodes and slices have been interpreted. Simulation result values of indoor air temperature during December 10th are presented and shows the influence of our hybrid solar wall on the thermal behavior of the habitat.
