Investigating the factors affecting the design and development of smart facades in cities based on a historical period

The smart facade system is known as one of the main elements of the building envelope with optimal efficiency, which is able to respond to environmental stimuli and seeks to improve the comfort of residents and optimize energy consumption. While building design research has addressed the technical aspects and design of smart facades, very limited historical studies have been conducted on the evolution of such systems. Therefore, the current research examines the factors affecting the design and development of smart facades in cities to optimize energy consumption based on a historical period. This article examines and classifies the effective historical components in the evolution of the design and development of the smart facade system using the historical hierarchy method. The effective components in the form of socio-cultural, technical, political, environmental and economic categories are caused by revolutionary changes in art, technology and building construction from the 19th century onwards. The findings showed that the historical timeline presented in this article is considered as a useful resource for researchers and educators in research and educational activities. Based on this table, the current development pattern can be understood and possible future events (trends) can be predicted. The timeline shows that smart facades can be used in the future on an urban scale for all neighborhoods of cities, which helps to improve the comfort of residents and improve energy consumption in cities.
