One of the common monuments in the Sassanid era was the square dome. Interestingly, corners and parts of the square dome were always geometrically proportionate to each other. Square domes have been mainly studied in terms of their historical background as well as the materials used. The present research, however, aimed to examine the geometric proportions governing the formation of square domes in the Sassanid era. The data were mainly gathered from field studies. First, the intended monuments were individually studied: the sizes were carefully measured and recorded. Then, the data were simulated by Auto CAD and the geometric repetitive proportions of the parts were extracted. The results indicated that the ratio of the corner depth to the radius of the dome circle was 0.3; the ratio of the angle length to the inward length was 0.11 and that of the outward side to the inward side was 1.6.

The strategies to reduce the consumption of non-renewable energies in buildings are becoming increasingly important. In the meantime, nature-inspired approaches have emerged as a new strategy to achieve thermal comfort in the interiors. However, the use of these approaches in architecture and buildings requires a proper understanding regarding the features of ecosystems. Although acquiring this knowledge requires a high degree of familiarity with the fields such as biology and environmental science, review of achievements made by the use of these features could facilitate the understanding of ecomimicry processes and thereby contribute to environmental sustainability in buildings. In other words, this paper concerns the relationship between these features and the thermal comfort inside the building. Biomimicry is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies. The objective of this paper is to use such review to provide an approach to the use of natural features for achieving thermal comfort in the buildings of hot and dry climates. In this review, the successful examples are analyzed to identify and examine the principles that influence the thermal comfort in both building and urban levels. The results show that the three elements of water, wind, sun are the effective natural resources that must be utilized in the design in a way proportional and consistent with the natural features. In addition, functional features of ecosystem can be of value only in the presence of a processual relationship between them.
