Strategies for Using Passive Solar Energy in Construction of Eco-Lodge in Xerothermic Climate Villages (Case Study of Dehsalm Village)

Introduction: Today, one of the global challenges is climate change caused by fossil fuels, which needs to be reduced by using renewable energies. In this regard, solar energy has been considered by many countries of the world due to its availability and high annual capacity, and researchers have also turned to use strategies to benefit from it in reducing energy consumption, including in buildings. These strategies can be considered an efficient strategy in the process of sustainable development, especially in rural areas. In addition to solar energy, tourism can significantly accelerate sustainable development in rural areas. Utilizing renewable energy within the tourism industry not only mitigates the sector’s environmental impact but also reduces operational costs for eco-tourism accommodations. This approach fosters the expansion of rural tourism while catalyzing sustainable development. Today, one of the global challenges is climate change caused by fossil fuels, which needs to be reduced by using renewable energies. In this regard, solar energy has received attention in many countries of the world, due to its availability and high renewable capacity. Researchers have also focused on using strategies to apply it for reducing energy consumption, including in buildings. This study aims to define practical strategies for eco-lodges, as an effective source of tourism and one of the main bases of sustainable development in rural areas. Reducing the costs of energy consumption, these strategies increase the economic justification of building eco-lodges and expand rural tourism, and consequently, provide new opportunities such as employment, reducing migration in these areas. Material and Methods: This paper is an applied research in terms of purpose and concerning the subject nature is "descriptive-analytical development". The area studied in this research is Dehsalam village in Nehbandan, east of Iran. In addition to describing the types of solar devices and their importance in xerothermic climates, this study has discussed the effective role of eco-lodge in the development of tourism in this climate and described the region's characteristics. Afterwards, it analyzed the climatic conditions of this region, using the software "Climate Consultant", and provided strategies to apply passive solar energy for the region and in general for regions with xerothermic climates. Results and Discussion: With the current trend of energy consumption and population growth, extraction from finite resources is continuously increasing. Considering the environmental debates surrounding the use of these resources and their pollution, moving towards renewable resources is considered essential. Among all the renewable sources, the use of solar energy has a suitable acceptance among different countries With the knowledge of the effective role of rural tourism in development in the light of providing energy needs if using the method presented in this research and providing conditions for sustainable development, especially in villages and deprived areas, reducing the operating costs of ecotourism residences by using systems Passive solar (static) to provide temperature comfort, reduce fossil fuel consumption, prevent air pollution, Destruction of the environment and its protection will lead to the prevention of climate change on a large scale if these strategies are developed and expanded. Conclusion: According to the results of this research, it was possible to provide strategies for the use of passive solar energy in reducing the consumption of fossil fuels in eco-lodges in a xerothermic climate. This will be a step towards limiting the contribution of the tourism industry to environmental problems, helping to reduce the costs of eco-lodges, creating economic attractiveness of this business, and facilitating the growth and expansion of rural tourism in xerothermic climate, as a driver for the sustainable development of these areas.
