“…In addition to that, the work of Alaa [44] indicated that the same system can reduce the amount of cooling load by 23%. In a study carried out by Bagasi [45] where authors used different techniques for indoor evaporative cooling systems in a hot and humid climate. They found that evaporative cooling system using wet cloth can reduced indoor air temperature by 26.3%.…”

The study investigated the level of thermal comfort in historical buildings located at a relatively high altitude in the Arabian Desert of Saudi Arabia. The study focused on the impact of the use of thermal mass and orientation on the level of thermal performance at Shubra and Boqri Palaces. Qualitative and quantitative analyses were used in this study, including a questionnaire interview with architecture experts living at the relatively high altitude of Taif city, to obtain data and information from local experts. The computer software TAS EDSL was used along with on-site equipment, such as thermal imaging cameras and data loggers, to observe the physical conditions of the building in terms of its thermal performance. The study revealed that the experts’ age and years of experience were important aspects while collecting data from them during the survey. The use of thermal mass had a slight impact on the indoor air temperature as well as the energy consumption, but it helped in providing thermal comfort. Use of ventilation can improve thermal comfort level. Evaporative cooling technique has a considerable impact on reducing indoor air temperature with 4 °C drop, improving the thermal comfort sensation level. The novelty of this work is that, it links the outcomes of qualitative results of experts with field monitoring as well as computer modelling. This can contribute as method to accurately collect data in similar case studies.

“…Special local raw materials, such as Kashour stone, were used for the construction of the houses (Al-Manqabi stone). Kashour stone is coral limestone (mined from the Red Sea coast and the Ruwais beach) but often Raffadi (marine stone) was used as an alternative (Bagasi and Calautit, 2020). The exteriors were made up of either one or two external differing facades and very rarely one might find a house with three facades (Al-Amoudi, 2018).…”

Purpose: Traditional houses in the Historic District of Jeddah exhibit architectural characteristics that reflect an important aspect of the social practices of the area in various historical contexts. This study aimed to clarify the link between the principles and characteristics of material cultural heritage (architectural characteristics) and a set of social practices, such as celebrations, that took place in the houses of the historical region of Jeddah. Furthermore, the study provided design guidelines for contemporary homes to support the social practices of celebrations in a modern context. These guidelines hope to preserve cultural stock and protect the traditional homes in the historical region of Jeddah from destruction. Design/methodology/approach:The study used the descriptiveanalytical method to characterize and analyse the architectural characteristics and social practices of well-known occasions in the region. Moreover, tangible and intangible heritage was investigated by employing the principles of design to elements of contemporary homes.

“…Although a region with a hot and humid climate is considered a hot region, the high level of humidity makes it difficult for the evaporative cooling system to work effectively [12]. In [13], which includes a case study from the city of Jeddah in Saudi Arabia, the analysed region is hot and humid. The study included an experimental field investigation for EC techniques with Mashrabiya.…”

Use of Underground Constructions Enhanced with Evaporative Cooling to Improve Indoor Built Environment in Hot Climate

Underground constructions (UGCs) have been used globally to accommodate a wide range of building usage, such as offices and shopping malls. Most of these constructions suffer from a lack of natural ventilation as well as daylight, as they are completely built under the surface of the earth. This has caused many issues related to discomfort, impacting the activity and the productivity of users. This study aimed to analyse the effect of the use of UGCs in hot regions, enhanced by partly elevated external walls which reach aboveground to ensure natural ventilation and daylight, with relatively small amounts of glazing to minimise the influence of solar heat gain. The study used a real built underground room with field measurements for indoor temperature and relative humidity. Moreover, the study used the computer tool EDSL TAS to simulate the performance of the model throughout the year after a field validation. It was concluded that the use of UGCs in hot climates should be encouraged as natural ventilation and daylight can decrease temperatures by 3 °C in summer, and the utilisation of evaporative cooling can cool the indoor environment by nearly 12 °C. Furthermore, heat transfer was highly affected by the external environment. It was found that the amount of heat transfer doubled in comparison between under and aboveground constructions. The use of small windows for ventilation caused high humidity, even in hot regions, during summer.
