Investigation of Natural Ventilation Techniques in Historical Buildings, a Case Study in PalermoC. Balocco
Energy Engineering Department, Università degli Studi di Firenze, Firenze, Italy
The natural ventilation of buildings provides improvement of internal comfort and air quality conditions leading to a significant reduction of the consumption of cooling energy.
In the present paper the air flow patterns, velocity and air temperature distributions inside a historical building in Palermo (Italy), at present used as a library, were investigated by a 3D transient simulation using COMSOL Multiphysics.
This study shows the effectiveness of a simple cooling technique and its operating conditions during the hottest days of the summer 2006 in Palermo. The simulation results are in agreement the values measured during an experimental study.
