“…Here the compromise is to offer sufficient privacy but with minimal restrictions on the benefits of windows such as daylight and ventilation. The mashrabiyya, a perforated wooden screen traditionally used in Middle Eastern nations, and wooden shutters have been examined in some studies of daylighting, ventilation and privacy [13][14][15] but traditional mashrabiyya are no longer a common choice. This paper reports an experiment conducted to investigate instead the privacy offered by two types of window treatments -horizontal blinds and frosted glass.…”

Cultural factors in Libya (and other Muslim countries) require female privacy to be maintained. Outside the home, females must wear clothing that reveals only the face and hands. When inside the home and located near windows, a similar degree of clothing cover or window treatment is required. This reduces exposure to natural daylight, with resultant reduction in health benefits of daylight. We are therefore investigating the degree to which window treatments offer sufficient privacy to permit relaxed clothing in the home. Two window treatments were tested: horizontal blinds and frosted glass, varying the free area and degree of frosting, respectively. The degree of privacy offered was operationalised by identification of the clothing level worn by a target behind the window treatment, the aim being to reduce identification to a chance level. For 0.3 s observations, only the extreme level of each treatment (horizontal blinds set to 3% free area and distortion level 20 for the frosted glass) led to chance levels of clothing identification, for both actors. For 3.0 s observations, there were significant differences in clothing identification, suggesting insufficient privacy.

The Arab Region embraces a diverse and substantial architectural heritage, with distinctive vocabularies and treatments, that has been as a source of inspiration for architects. However, the contemporary Arab architectural production is not at the desired level. So, the study questions the reasons for the success of Traditional Architecture in providing environmental Comfort and achieving human requirements. Besides, the study explores literature reviews of contemporary trends of studies that are concerned with employing the foundations and principles of Traditional Architecture. Therefore, this study firstly, presents a theoretical background of environmental comfort then extracts the foundations and standards of Traditional Architecture in the Arab Region, with the aim of deducing a Conceptual Framework of Traditional Architecture as a guide to Contemporary Architecture and finally a literature review of recent trends in environmental architectural studies based on traditional strategies. The results of this part show that the studies are divided into three approaches: 1) Philosophical studies that attempt to analyze Traditional Architecture to reach success criteria for traditional architecture. 2) Innovative strategies dealing with modern proposals to achieve environmental comfort based on the principles of sustainable traditional architecture. 3) Studies that focus on analyzing and developing one of the elements that distinguish Traditional Architecture. As a final point, the study presents a Systematic Framework to employ all the standards of traditional architecture and exploiting all the results of contemporary studies to serve as a guide for Contemporary Architecture.

“…Conversely, Aljofi [19] confirmed that the critical assessment of Rawshan thermal output, with its natural ventilation capacity, should always be pursued to produce environmentally sensitive screens of the Rawshan. On the other hand, Gelil M and Badawy [20] prevented the revival of the Rawshan's (Mashrabiyyah) screen in countries such as Egypt due to air pollution. Nevertheless, the ventilation factor seems to be perceived as a limitation in the Western Region of Saudi Arabia (Hedjaz) as discussed in Chapter 5, Section 5.3.2.…”

Public Perception of Vernacular Architecture in the Arabian Peninsula: The Case of Rawshan

2020

View full text Add to dashboard Cite

This research extends Hasan Fathy’s (1986) principle of vernacular architecture by focusing on the Rawshan through an investigation of two criteria: aesthetics and energy efficiency. The paper discusses the views of both the Saudi public and key decision-makers on reviving vernacular architecture in the context of Saudi Arabia’s rapidly developing economy, characterized by relatively high rates of energy consumption and CO2 emissions. This research explores (a) the interaction in domestic buildings of Saudi occupants with their windows, and how these are perceived as an interface with the external environment; (b) awareness and knowledge of the use of shading elements (such as Rawshans) to reduce the use of artificial lighting while maintaining indoor privacy; (c) Saudi awareness of, and familiarity with, the Rawshan as a vernacular element and a secular architectural tradition; and (d) Saudi views on the revival of traditional architectural elements with a focus on the Rawshan. An online survey (n = 812) was conducted across Saudi Arabia complemented by interviews with expert decision-makers (n = 23) to (a) assess criteria such as privacy, aesthetics, daylight, ventilation, and energy consumption in Saudi residences and (b) investigate the level of acceptance of an optimized retrofitted Rawshan design.
