• Abstract:

  The new designs of homes and buildings contemplate the use of alternative sources and ventilation plays an important role. Ventilation can be induced by passive and active systems, the latter using mechanical means, which causes high electrical energy consumption. Within the passive ventilation systems we can mention Wind Towers, Trombe Walls, Double Facades and Solar Chimneys, each of these systems are capable of inducing air through the premises using natural energy sources such as wind and/or solar energy. This work presents the detailed energy balance of a solar chimney and its solution algorithm.
