“…Emami and Giles. [187] studied the effects of geometric parameters as shading screens on daylighting, using the underlying principles of IGPs. Oghazian et al [188] investigated the influence of seven types of IGPs and the non-uniform distribution of openings on solar screens installed on a south-facing façade of an office room from a daylighting performance perspective.…”

Currently, there is a tendency to use Islamic Geometric Patterns (IGPs) as important identities and cultural elements of building design in the Middle East. Despite high demand, lack of information about the potential of IGPs principles have led to formal inspiration in the design of existing buildings. Many research studies have been carried out on the principles of IGPs. However, comprehensive studies relating to new possibilities, such as structure-based, sustainable-based, and aesthetic-based purposes, developed by computer science and related technologies, are relatively rare. This article reviews the state-of-the-art knowledge of IGPs, provides a survey of the main principles, presents the status quo, and identifies gaps in recent research directions. Finally, future prospects are discussed by focussing on different aspects of the principles in accordance with collected evidence obtained during the review process.

“…Screens, based on the documented geometric parameters, were modelled in computational environments with an objective of optimizing them for energy and visual comfort performance for different climates. [29][30][31][32] The geometric parameters of screens that have been frequently researched are perforation ratios (PR, i.e., % of open), depth ratios (DR, i.e., opening depth to opening width ratio) and perforation geometry. Screens with PR = 80 to 90% and DR = 0.5 or 1 provided optimum daylighting and cooling energy savings compared to non-shaded conditions.…”

External dynamic screens, inspired from geometric patterns of vernacular screens, are popular building facade treatments because of their aesthetic significance. Their potential to impact building cooling energy demand and visual comfort has been well-realized, However, their impact on occupant com¬fort has been under-researched. This study is part of a larger research problem that investigates the impact of external dynamic screens on occupants’ thermal comfort and ‘alliesthesia’/thermal pleasure. This paper focuses on investigating the sensitivity of predicted thermal comfort to geometric parameters of a screen using computational simulations. Results from this sensitivity analysis were used to address the question, as to how can external dynamic screens be designed to create transient yet comfortable thermal environments. The present study formed a basis to inform the design and development of screen prototypes and experiments involving human subjects. It provides architects and architecture students with an approach, where design intentions impact occupant thermal delight, beyond aesthetics.

“…Geometric patterns along with calligraphy and floral patterns are the most renowned visual tradition in Persia and the surrounding regions socio-cultural values (Broug, 2013). The prohibition of anthropomorphic forms resulted from religious beliefs and created the potential for growing sets of geometric patterns (Abas & Salman, 1992;Emami & Giles, 2016). Geometric patterns can be classified based on both the practical experience of tiling and general geometric construction rules and mathematical facts (Abas & Salman, 1992, Abdullahi & Embi, 2013Emami, Khodadadi, & Von Buelow, 2015, Sarhangi, 2012.…”
