Abstract
In an investigation into wind-induced natural ventilation performance in buildings, this study uses Computational Fluid Dynamics to examine the effect of integrating wind catchers with curved roofs, implementing three-dimensional modelling. It is intended to give more value to the symbolic role of the dome, vault and tower in architectural design. The early findings of this study revealed that curved roofs induce natural ventilation in buildings by suction. This is generally true for the central and upstream zones of deep-plan buildings, but not for the downstream zone. Thus, wind catchers can be used to overcome this problem. This has been investigated by considering different geometrical and climatic parameters. The results show that the proposed ventilation system increases airflow rates and improves internal airflow distribution.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
