It is necessary to design structures with fabrics indicating the culture and identity, in such metropolises as Mashhad, in buildings like educational buildings, which are regarded as public, crowded buildings with high effects on society and could form a great number of buildings over the city. In this regard, attentions are mostly directed at creating designs which more adapt to the climatic features and increase the level of comfort. In the current study the focus is on folding surfaces with some kind of pantographic shell used in educational places. The study is mainly concerned with presenting a way for improving the efficacy of the smart models in designing the ceilings with folding shells. The studied pantographic structures were structures with elliptical arch, extensive folding structures with elliptical arch and domal folding structures with elliptical arch, which most of the time require a cover to protect them from the rain, sunlight or wind and could be connected to the main structure itself. In the current study, it is attempted to present a strategy for increasing and improving the efficacy of smart models for designing ceilings with folding shell, considering the climatic situation, tempreture and the residents’ density in the educational building. From the objectives viewpoint, the research method is practical, and it is attempted to define a new design in a practical way and achieve some palpable results to implement the results of the study, using two software programs of Designbuilder and Matlab. Accordingly, the situation was considered in the schools from the scale of 10, based on the the smart models for designing ceilings with folding shells and the distributed thermal comfort level based on the simulated models. The results show that there is a relationship between the matter mentioned and the optimization of energy consumption. With regards to the instruction of double-skin folding shell used in summer and winter, it was indicated that the best plan of smart double-skin folding shell for obtaining the best situation for air conditioning is the instruction of double-skin folding (opening) shell used for 6 hours in summer and 2 hours in winter, the instruction of double-skin folding shell (opening) used for 6.5 hours in summer and 2.5 hours in winter and the instruction of double-skin folding shell (opening) used for 5.5 hours in summer and 2 hours in winter.

This research deals with an efficient approach to achieve the optimization of energy consumption by emphasizing the selected and optimized features in the two-shell facade and in the form of a general question under the title that the application of two-shell facades in towers How multipurpose can lead to reduction of energy consumption and thermal comfort in the cold and dry climate of Mashhad city. The crisis of energy is one of the greatest concerns that the world is facing today, especially in the area of building and architecture. Considering the limitations of determining the areas related to high-rise construction and compiling special construction rules in Mashhad city, in this dissertation, the researcher found the maximum height in the selected sample to be 150 meters with 34 floors as the first. and it is considered the tallest building in Mashhad city, in addition, according to the two tables and considering the most prominent tower in terms of being the tallest and also having the highest number of floors (on average), considering that Some of these towers are older in terms of age and have a lower height, and the towers under construction in Mashhad are on average taller than some of these towers, even though they are famous and prominent, and in addition One reason for choosing the tallest tower with the highest number of floors is that the effect of the variables investigated in this thesis increases with the increase in height, and in this thesis, solutions for the tallest towers are also supposed to be given. Accordingly, in order to investigate the function of double-skin facade and its effect in the climate of Mashhad City and to select a suitable option from amongst four types of double-skin facade, in the current study, first, four types of double-skin façade (multi-story, shaft-box, corridor, box-window) are considered in terms of energy in the climate of Mashhad City which is a cold and arid region, and the study is conducted on a multi-purpose and high-rise building in order to find the most optimal state for the region of Mashhad, and then the speed of wind and the air flow temperature in the façade shall be analyzed and the findings and conclusion of the study shall be presented The results of the study showed that the increase of the depth of middle hole leads to the improvement of the thermal function of the whole double-skin façade with an average of thermal comfort limit.
