Natural Ventilation in Low-Cost Housing: An Evaluation by CFD

With the spread of sustainability concepts, due to global energy crisis and unrestrained consumption natural resources, importance rational use reduction has been intensified, albeit in short steps. This concern taken up bioclimatic concepts buildings, especially housing buildings for low-income people, aiming at improving quality production terms its habitability. The objective this research is theoretically experimentally study ventilation a building, which fits into low-cost pattern. Computational Fluid Dynamics predict was adopted as tool perform these analyses. Experiments were carried out by visiting area collect data on air velocity, temperature, relative humidity all rooms residence order carry intended Computer simulation considering building with doors windows open fixed geometry performed. Results proved that proposed mathematical model able reproduce, rich details physical coherence, internal external flow inside indicating better performance environments have door window openings, recesses, revealing cross reduce temperature consequent improvement thermal comfort. idea help civil engineers specialists economically viable design from economic, social, comfort points view.
