Abstract :
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.
