This concern has taken up bioclimatic concepts in buildings, especially housing buildings for low-income people, aiming at improving the quality of housing production in terms of its habitability. The objective of this research is to theoretically and experimentally study the natural ventilation in a housing building, which fits into the low-cost pattern. The use of Computational Fluid Dynamics to predict natural ventilation was adopted as a tool to perform these analyses. Experiments were carried out by visiting the study area to collect data on air velocity, temperature, and relative humidity in all rooms of the residence in order to carry out the intended analyses. Computer simulation of natural ventilation considering the building with the doors and windows open and with fixed geometry was performed. Results proved that the proposed mathematical model was able to reproduce, with rich details and physical coherence, the internal and external air flow inside the building, indicating better internal ventilation performance in environments that have door and window openings, with recesses, revealing the importance of cross ventilation to reduce the internal temperature and consequent improvement in thermal comfort. The idea is to help civil engineers and specialists in the economically viable design of low-cost buildings from the economic, social, and thermal comfort points of view.<\/jats:p>","DOI":"10.3390\/buildings13061408","type":"journal-article","created":{"date-parts":[[2023,5,30]],"date-time":"2023-05-30T02:04:21Z","timestamp":1685412261000},"page":"1408","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Natural Ventilation in Low-Cost Housing: An Evaluation by CFD"],"prefix":"10.3390","volume":"13","author":[{"given":"L\u00edvia A.","family":"Rocha","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Federal University of Campina Grande, Campina Grande 58429-900, Para\u00edba, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4387-4600","authenticated-orcid":false,"given":"Ricardo S.","family":"Gomez","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Federal University of Campina Grande, Campina Grande 58429-900, Para\u00edba, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1026-4523","authenticated-orcid":false,"given":"Jo\u00e3o M.
