Residential use analysis of Mashhad based on LEED indicators in green buildings

The hotel industry, as the largest subset of the tourism industry, is one of the largest polluters among the service industry. Quoting from Elsevier's valid scientific journals such as Sustainable Futures and Cleaner Production in 2022 and 2023, the negative environmental impacts of hotels are greater than the impacts of buildings with different uses of the same size and scale. On the other hand, hotels in the pilgrimage city of Mashhad are one of the most important uses, which is ranked first in Iran. Undoubtedly, the approach of optimal use and energy saving is very important in this industry. Therefore, this article aims to improve the quality of urban construction and reduce the use of resources and energy in hotels in Mashhad and using a descriptive-analytical method to identify the principles and criteria of green building and analyze the status of hotels in three sections: hotels, apartment hotels And hosts. The statistical population of this research includes all hotels of Mashhad and sample size with cluster sampling method of 169 cases. The international LEED standard has been used to evaluate green building indicators. The results show that hotels reveal many weaknesses that can be traced back to the early stages of design to construction and after implementation. These buildings do not benefit from the basics of green building principles and are buildings with high energy and water consumption, and none of them have obtained the minimum score required to obtain LEED certification (40 points). Therefore, after stating the causes, practical solutions to solve them are presented.
