The role of the fluid dynamics for green buildings performance

Industrial development and the continuing urbanization have implications on the preservation of natural common resources and have caused global and micro-environmental pollution. Building construction sector contributes in a decisive way to the planet's energy consumption and it is universally recognized that it is not possible to focus on economic development without taking into account the sustainable environmental resources. The increased awareness of these issues arouses a growing interest in eco-friendly building construction. In the design phase of a building, one of the most important phenomena and the most complex to envisage is the air flows inside and outside of the building in order to evaluate its energy performance, thermal comfort and air quality. The CFD simulations (Computational Fluid Dynamics) are considered the most advanced tool for the analysis of air distribution and of the related thermal effects caused by it..
