Abstract
With the rapid expansion of construction activities, the growing trend toward high-rise development and mass housing production, and the pressing demand for optimized residential solutions in developing countries, increased attention has been directed toward advanced construction methods and technologies. Given Iran’s location within the central Alpine seismic belt and the recurrent tectonic activity along regional fault lines, structural lightweighting and dead-load reduction have become increasingly critical for enhancing seismic resilience and overall structural performance. The adoption of modern lightweight materials—which offer reduced weight, accelerated construction schedules, extended service life, and superior structural integrity—has thus become a pressing necessity. To meet contemporary societal demands, Iran requires the development of high-rise buildings with greater floor counts and faster execution rates. Conversely, conventional building materials have demonstrated significant inefficiencies in three key areas: structural performance, excessive energy consumption during both manufacturing and operational phases, and prolonged construction timelines in mass-production scenarios. These factors have inadvertently increased construction costs, slowed project delivery, and introduced substantial challenges to the building industry over recent decades, with economic losses already evident and projected to further diminish the useful lifespan of structures. Furthermore, Iran consumes substantial amounts of energy annually in the residential sector. According to estimates by the Iranian Fuel Conservation Organization, buildings account for approximately 38% of the country’s total fuel consumption. Given the high proportion of final energy consumption in the residential sector, precise calculation and analysis of thermal and cooling loads, alongside targeted efforts to minimize energy losses, represent highly effective strategies for reducing heating and cooling energy demands. Implementing these measures is particularly critical in light of Iran’s recent targeted subsidy reforms, which have heightened the economic and strategic importance of energy efficiency. As demonstrated in this study, adherence to these principles can yield substantial national savings in both resources and economic capital.
