In perspective of achieving energy-efficient buildings, it's important the study of natural ventilation and cooling systems for residential environments that can exploit solar heat source. Correct exposure of the building already allows exploiting the passive ventilation between rooms. Other different strategies can provide natural ventilation without the constraint of exposure. Among the various systems to achieve this, the present study conducts a feasibility study of a solar chimney to be used for natural ventilation of the summer living environments. It is addressed in two-dimensional geometry, the study of thermo-fluid dynamic system installed inside a solar chimney of a size comparable with the enclosures housing. The system consists of a chimney in the center of the building to which the air vents of different environments are connected. The heat is provided at the base of the chimney by a horizontal plate heated by water storage system "charged" during daytime through solar thermal natural convection. Different operating conditions are simulated using a model CFD (Computational Fluid Dynamics) by varying the size of the chimney in order to calculate flow rates and velocities occurring in different configurations.
