Effect of openings location on the ventilation efficiency in dwellings

Building ventilation implies managing the "clean" air and extracting the contaminated air through the walls, distributing and circulating the incoming air and preventing the contamination of the indoor air. The Spanish Technical Building Code, in his section HS3 - IAQ, usually set up minimum ventilation flow rates according to its typology, surface, possible contamination sources or the number of occupants, without thinking over the path of the air from the inlet to the exhaust point. For that reason, even if such standards are met within the spaces of the home, there may still be areas in the interior that suffer an excess or deficit of ventilation. The present study aims to overcome the purely quantitative performance of DB-HS3, to control qualitatively the air renewal throughout the living space; this allows even to reduce the volumetric flow rate with the consequent energetic saving.
