“…On the roof coverings, the windcatcher has a variety of shapes, including flat roofs, sloped roofs and curved roofs. According to Esfeh, the shape of a curved roof has the best performance that can reduce airflow resistance than other forms [16]. A similar thing was expressed by Hughes [14] ( Figure 6).…”

The high energy use for building operations in humid tropical climates is mostly used for operational mechanical ventilation such as air conditioning (AC) and fans. The use of large amounts of energy, especially fossil energy can reduce the quality of the environment, causing an increase in the temperature of the earth. Need more efforts for management of energy use by reducing fossil energy consumption. One effort that can be done is to replace mechanical production and utilize passive ventilation in buildings. this study is a literature review regarding the use of passive ventilation using a windcatcher integrated with solarc himneys. The use of windcatcher and the solar chimney is still very rare in Indonesia, but has the potential to solve thermal problems, especially in densely populated residential areas in cities that have the character of a humid tropical climate. The results of this study recommend criteria from windcatchers and soler chimney that might be applicable and adapt to the character of the urban humid tropical climate.

“…Recent studies in KSA have identified Radon ( 222 Rn) gas as another indoor air pollutant (Abo-Elmagd et al, 2018;Alghamdi and Aleissa, 2014). Moreover, it has been reported that indoor air pollution in most cities in the GCC region is due to the infiltration of ambient air pollutants into residential buildings, poor ventilations, burning of biomasses (Arabian incense), and overcrowding (Argyropoulos et al, 2016;Fadeyi et al, 2014;Jomehzadeh et al, 2017;Weitzman et al, 2016;Yaghi and Abdul-Wahab, 2003). For example, incomplete burning of Arabian incense emits CO, PM 10 , PM 2.5 , polycyclic aromatic hydrocarbons (PAHs), and black carbon (BC), which cause deleterious health effects for the exposed population (Du et al, 2018).…”

“…In practice, buildings are attached with various types of envelope features on their facades, such as balconies, bay windows, wing walls and overhangs (see Fig. 1) and wind catchers (Jomehzadeh et al 2016;Hughes et al 2012;Pak et al 2018). These envelope features are designed for architectural and/or functional purposes, some of which were proved being able to mitigate noise, moderate the transport of heat and air and reduce transmission of daylight from outside to indoor environments (Ai et al 2013;Mak et al 2005Mak et al , 2007Niu 2004).…”

This study examines the influence of building envelope features on interunit dispersion around multi-story buildings, when the presence of an upstream interfering building is also considered. Validated CFD methods in the steady-state RANS framework are employed. In general, the reentry ratios of pollutant from a source unit to adjacent units are mostly in the order of 0.1%, but there are still many cases being in the order of 1%. The influence of envelope features is dependent strongly on the interaction between local wind direction and envelope feature. In a downward dominated near-facade flow field, the presence of vertical envelope features forms dispersion channels to intensify the unidirectional spread. Horizontal envelope features help induce the dilution of pollutant to the main stream and weakens largely the vertical interunit dispersion. The large influences caused by the presence of envelope features extend the existing understanding of interunit dispersion based on flat-facade buildings.
