This is an open-access article under the CC-BY-SA creativecommons. org/licenses/by-sa/4. 0/ | 585 Sustainability in Historical Islamic Architecture: Lessons from Sheikh Lotfollah MosqueAos Construction Techniques apparent in today's world, where we are facing environmental challenges and the need to design sustainable The analysis of Sheikh Lotfollah Mosque can help to understand the principles of sustainability in Islamic architecture and provide solutions to revive these principles in contemporary architecture. In an era when architects seek to combine new technologies with traditional methods . , this research can act as a bridge between the past and present and provide valuable models for future designs. Therefore, the detailed investigation and analysis of this mosque not only helps to preserve the cultural heritage but also helps to develop sustainable architecture. Any type of research and scientific research should refer to the history and background of that subject so that one can start researching with sufficient knowledge of the gaps and unmet needs. In this regard, in this article, several researches that have been studied in recent years are briefly brought up, and the results are stated in Table 1. Tabel 1. Research Background Research Reference . Year of . Results The study's findings suggest that the Sheikh Lotfollah Mosque's transformational principles are attributable to the index of spatial geometry, which is triggered by rotation, direction change, and translational movement of structural and physical elements, external walls, and connecting internal Four pillars of calm, movement, connection, and union are specified for perception in Safavid mosques, according to Mulla Sadra's spiritual process at the perceptive levels. The audience's perspective may improve at each level following the stability stage for several reasons. In the movement pillar, through necessary movement. in the connecting column, through light and and, lastly, in the unity pillar, through the connection of the space and the observer. The observer's ability to perceive more clearly is facilitated by these factors, first at the sensory level and subsequently at the imagined and rational levels. The research's conclusions demonstrate that, with a value of . , the shaping of large and small spaces as altars, ponds, shrines, mosque courtyards, and domes has the largest factor contribution, while the least significant factor contribution is associated with architectural materials . The way that the spaces were arranged in the mosques during the Safavid era, particularly in the mosques of Sheikh Lotfollah and Imam, produced a rich and unexpected combination as well as serene and lovely spatial impressions. The results indicate that this inscription's text is a hadith, referred to as the Hadith of Jabir. This study further demonstrates that 'Ali-Reza 'Abbasi, a well-known and accomplished calligrapher from the Shah Abbas I era, was the person who wrote this inscription. The analysis's findings indicate that as mosques' surfaces increase, so does the amount of heat absorption exposed to radiation and in the shadow area. Therefore, domes with rising surfaces and high heights that create shade are appropriate for hot, dry climates, while domes with rising surfaces and high contact surfaces that receive radiation are ideal for cold, dry climates. The findings highlight the salient features of Sheikh Lotfollah mosques' sense of place, including the entrance, hallways, walls, ceiling, mihrab, and dome. light and substance enable the triangular union of physical elements to transition from appearance to conscience. Thus, at the greatest level, a deep internal dialectical link between Sheikh Lotfollah and its observer establishes a sense of location. The results of the research show that in the inscriptions of the minarets, a combination of the main conclusions of the current article's studies are presented to create a framework that can aid in the construction of other mosques and structures with comparable areas. The study's findings confirm that the primary causes of the damage were rising moisture levels brought on by nearby sewage and water line leaks. Thus, among the needs for the restoration project are pipe repair, grouting of the foundation, and area organization. The findings indicate that the mosque entrance corridors in Isfahan are curved and rotated, maybe to facilitate the prayerful vision of a bright, spiritual space beyond the dim, narrow passageway leading to the prayer hall. The findings indicate that, just during Nowruz, the number of visitors to the Sheikh Lotfollah Mosque exceeded its actual daily bearable capacity, whereas, during other months of the year, it was significantly less than its actual monthly tolerable capacity. As a result, the policies required to run this building during times of prosperity and recession are essential to avoid permanent harm to this historic structure. 586 | Journal of Islamic Architecture 8.

This concept includes the optimal use of natural resources, reducing energy consumption, and creating healthy and livable environments for humans . , . In recent years, with increasing public awareness of climate change and the need to reduce the negative effects of human activities on the environment, sustainability in architecture has become one of the most important topics in this field . , . Sheikh Lotfollah Mosque, one of the prominent examples of sustainable architecture in the Safavid era, has always been studied and analyzed. With its intelligent design, this mosque shows how the architects of that period were able to achieve sustainability in architecture by using simple but efficient techniques. Among the techniques used in this mosque, we can mention the use of natural light for lighting, natural ventilation for temperature control, and the selection of native and local materials for construction. These techniques not only help to reduce energy consumption but also increase the durability and longevity of the building. In this regard, the plan of Sheikh Lotfollah Mosque has been presented with a comprehensive analysis, in which natural ventilation and natural lighting, especially the location of windows, have been determined graphically and using Photoshop software (Figure .

Comprehensive analysis of Sheikh Lotfollah mosque plan USE OF NATURAL LIGHT One of the most prominent features of Sheikh Lotfollah Mosque is the intelligent use of natural light. The interior design of the mosque is such that sunlight does not enter the interior directly, and this makes the interior always bright, without the need for artificial light sources. It helps to reduce energy consumption and, at the same time, makes the indoor space more pleasant for worshippers. Table 12 examines the features, benefits, challenges, and potentials of using natural light in contemporary buildings inspired by the design of Sheikh Lotfollah Mosque. Table 12.

In response to this question, several basic aspects can be mentioned: USING NATURAL LIGHT IN CONTEMPORARY BUILDINGS In contemporary buildings, the use of natural light can help reduce energy consumption. With the appropriate design of windows and the use of new technologies such as smart glass, sunlight can be used more efficiently. This not only helps to reduce energy costs but also improves the interior of buildings and provides a more pleasant environment for residents. NATURAL VENTILATION AND TEMPERATURE CONTROL By using natural ventilation techniques, it is possible to control the internal temperature naturally in contemporary buildings. Using dome roofs or opening windows in strategic points of the building can help air circulation and reduce the need for artificial heating and cooling systems. These techniques can be very useful, especially in tropical and subtropical regions. USE OF LOCAL AND INDIGENOUS MATERIALS In the design of contemporary buildings, the use of local and indigenous materials not only helps to reduce construction costs but also leads to the stability and durability of the buildings. In addition, the use of local materials reduces transportation and thus reduces greenhouse gas emissions. This issue can be considered as one of the basic principles in the design of sustainable buildings. CHALLENGES AND OBSTACLES Table 16 is dedicated to the examination of challenges and obstacles that may be encountered in the implementation of sustainability techniques, such as those used in Sheikh Lotfollah Mosque, in contemporary Table 16.

Among these challenges, the following can be mentioned: CLIMATIC CHANGES AND GEOGRAPHICAL DIFFERENCES One of the main challenges in using the architectural techniques of the past is climatic changes and geographical differences. For example, the natural ventilation techniques used in the Sheikh Lotfollah Mosque may not be as efficient in areas with different climates. For this reason, contemporary architects should choose and apply appropriate techniques according to the specific conditions of each region. ECONOMIC CONSTRAINTS The use of sustainability techniques may increase initial construction costs. Although, in the long run, these techniques can help reduce energy and maintenance costs, the initial costs may not be acceptable for many projects. Therefore, architects and designers should look for solutions that are both economically viable and adhere to the principles of sustainability. NEED FOR EDUCATION AND AWARENESS Another obstacle to using sustainable techniques is the lack of awareness and knowledge about these To optimally utilize these techniques, there is a need to educate and raise awareness among architects, designers, and even clients. This issue can be addressed through educational programs and specialized workshops in the field of sustainable architecture. DISCUSSION
