The built environment is responsible for approx. 40% of the total energy consumption, and a significant part comes from maintaining an appropriate indoor comfort environment by heating ventilation and air conditioning. Though contemporary studies have achieved a wide knowledge about natural ventilation and passive air conducting systems (PACS) and their applicability, further investigations are necessary to deepen the aerodynamic topology of air conducting building structures’ shape properties. Hence, in our current research we conducted a series of tests applying different wind catcher geometries. The methodology of this work is based on the authors’ previous work, where passive air conduction systems were compared with different airflow directions via computational fluid dynamic simulations (CFD). After finding the better performing PACS (a downdraught system), this research evaluates whether further improvements in ventilation efficiency are possible due to the aerodynamic shaping of the roof integrated inlet structures. Four different wind catcher geometries were examined to determine the most advantageous dimensional settings in the natural ventilation system’s given boundaries. After multiple series of basic and developed calculation runs, diverse shape designs of the passive air conduction inlet (PACI) were examined, including wind deflector geometries. The initial reference wind catcher’s air change rate was increased by approx. 11%. The results deliver the potential measure of improvements achievable in the aerodynamic shape design of structures under identic conditions of the same building domain. As a consequence, more sophisticated natural ventilation structural solutions will be possible in more operation cost- and performance-effective ways.}, year = {2022}, eissn = {2075-5309}, pages = {1583-1608}, orcid-numbers = {Katona, Ádám László/0000-0003-2885-4596} } @article{MTMT:32073743, title = {Comparison of Downdraught and Up Draft Passive Air Conduction Systems (PACS) in a Winery Building}, url = {https://m2.mtmt.hu/api/publication/32073743}, author = {Katona, Ádám László and Háber, István Ervin and Kistelegdi, István}, doi = {10.3390/buildings11060259}, journal-iso = {BUILDINGS-BASEL}, journal = {BUILDINGS}, volume = {11}, unique-id = {32073743}, year = {2021}, eissn = {2075-5309}, pages = {259-279} } @{MTMT:32200293, title = {Evaluation and optimization of different wind tower geometries for passive air conduction systems with CFD simulations}, url = {https://m2.mtmt.hu/api/publication/32200293}, author = {Katona, Ádám László and Kistelegdi, István}, booktitle = {InnoRenew CoE International Conference 2021: Healthy and Sustainable Renovation with Renewable Materials}, unique-id = {32200293}, year = {2021}, pages = {54} } @{MTMT:32490336, title = {Parametric Sensitivity Analysis of Venturi Roofs’ Ventilation Performance with 2D CFD Simulations}, url = {https://m2.mtmt.hu/api/publication/32490336}, author = {Katona, Ádám László and Kistelegdi, István}, booktitle = {Abstract book for the 17th MIKLÓS IVÁNYI INTERNATIONAL PHD & DLA SYMPOSIUM}, unique-id = {32490336}, year = {2021}, pages = {p.51} } @{MTMT:32507749, title = {Natural Ventilation Enhancement toward Reducing Energy Consumption in Family House Buildings}, url = {https://m2.mtmt.hu/api/publication/32507749}, author = {Ali, Modar and Katona, Ádám László and Kistelegdi, István}, booktitle = {Abstract book for the 17th MIKLÓS IVÁNYI INTERNATIONAL PHD & DLA SYMPOSIUM}, unique-id = {32507749}, year = {2021}, pages = {74}, orcid-numbers = {Ali, Modar/0000-0001-9585-2684} } @CONFERENCE{MTMT:32526234, title = {Parametric sensitivity analysis of Venturi roofs’ ventilation performance with 2D CFD simulations}, url = {https://m2.mtmt.hu/api/publication/32526234}, author = {Katona, Ádám László and Kistelegdi, István}, booktitle = {10.
