The data presented in this article were the basis for the study reported in the research articles entitled "Evaluation of a two-sided windcatcher integrated with wing wall (as a new design) and comparison with a conventional windcatcher" (P. Nejat, J.K. Calautit, M.Z.A. Majid, B.R. Hughes, I. Zeynali, F. Jomehzadeh, 2016) [1] which presents the effect of wing wall on the air flow distribution u...

This article presents the datasets which were the results of the study explained in the research paper 'Anti-short-circuit device: a new solution for short-circuiting in windcatcher and improvement of natural ventilation performance' (P. Nejat, J.K. Calautit, M.Z. Abd. Majid, B.R. Hughes, F. Jomehzadeh, 2016) [1] which introduces a new technique to reduce or prevent short-circuiting in a two-si...

We investigate and test the effectiveness of a novel window windcatcher device (WWC), as means improving natural ventilation in buildings. Using ANSYS CFX, performance window-windcatcher is compared to control case (no window-windcatcher), three different geographic locations (Cardiff, Doha Amman) which are representative types atmospheric conditions. The proposed has been shown improve both th...

Previous studies on window-windcatchers have shown their effectiveness in capturing the prevailing wind and redirecting it into a building, increasing actual-to-required ventilation ratio by 9%, above what is required American Society of Heating, Refrigerating, Air-Conditioning Engineers (ASHRAE). However, effect implementing proposed system energy performance, costs, thermal comfort has not be...

This paper investigates the function of windcatchers in dry regions in Middle East and compares them in different fields in two areas including Yazd-Iran, and Egypt. The study examines windcatchers in these areas in terms of cooling system and forms, with different plans, forms, constituent components and decorations.Reassessment of windcatchers in these areas can shed light on these difference...

Window-windcatchers, a passive ventilation method, have been shown to improve and enhance thermal comfort. Preliminary characterization of novel window-windcatcher has undertaken in previous work, but no relationship had identified between the actual rate (Qact), wind velocity (VTw) crucial design parameters such as fins angle (ϴ)). In this paper, that quantifies how window-windcatcher’s perfor...

The provision of good IAQ in schools is important both for the health of students and in maximising educational achievement. It is, however, common for school classrooms to be significantly under-ventilated and this can lead to high levels of CO 2 and other pollutants. Natural ventilation offers the potential to improve IAQ within schools whilst at the same time reducing running and maintenance...
