Investigation and modeling of energy consumption of tall office buildings in Iran's `hot-arid' and `cold' climate conditions[Assessment of energy saving potential by replacing conventional materials by cross laminated timber (CLT)—a case study of office buildings in China]

The construction of high-rise buildings has attracted human attention at the beginning of human civilizations’ formation. Presently, making tall buildings is considered as a necessary requirement due to the succeeding reasons: the population increase, the tendency to live in urban centers, the land utilization in the most populated centers of the cities, the need to decrease the cost of horizontal development of cities and technological advances. During the last century, issues related to environmental pollution and high energy use have affected these tall buildings. So, it is crucial to apply appropriate methods and patterns in order to adjust their environmental impacts as much as possible. In addition, the building industry accounts for a significant amount of energy consumption in the world. Therefore, energy-saving and efficiency can be mentioned as a significant issue due to the limitation of fossil resources. The importance of this issue has been increased by eliminating subsidies and realizing the price of fuels in Iran. Efforts in the field of high-rise buildings in Iran are chiefly based on general criteria regarding the location and characteristics of urban imagery and the field of urban design knowledge. The efforts contributed to the energy consumption have not been carried out. The present study provides patterns for the aim of designing high-rise buildings with official use in Tabriz and Yazd. The solutions for the opening design of tall buildings with regular forms to reduce energy consumption are proposed in this study.
