Conceptual implementation of natural ventilation strategy

The necessity of focus on more large integration of passive concepts for indoor climate conditioning is today a reality. Through this study, a contribution to fill the lack of useful design guidelines for natural ventilation is proposed, in order to develop the passive ventilation systems implementation. Besides a methodological approach, the paper proposes conceptual tools. The implementation of a natural ventilation strategy includes the envelope building design, the indoor spaces layout and the component sizing. This study explores an architectural classification of ventilation systems. The ventilation system involvement is underlined through evaluation of  ventilation  efficiency  concerning  two  natural ventilation systems using ducts.
