Therefore, we can significantly reduce costs and carbon emissions by employing appropriate technologies and efficient structural systems. For example, tall buildings require extensive structural materials ( Krummeck and MacLeod, 2016). Therefore, the extracted design elements, principles, and recommendations from the case studies examined in this article are substantial. This research is significant because, given the mega scale of skyscrapers, any improvement in their design, engineering, and construction will have mega impacts and significant savings. The prime goal of this research is to map out “green” design ideas that contribute to the sustainability of tall buildings. Similarly, incorporating innovative engineering and architectural solutions helps capture and recycle rainwater, further reducing the likelihood of flooding ( Yeang, 2008 Wang et al., 2018). Integrating green elements in buildings and their surrounding will surely help to absorb rainwater. The “sponge city” model builds on the Green Infrastructure (GI) model that aims to improve water management systems and enhance the ecological wellbeing of urban habitats. Urban planners have recently developed new models, for example, a “sponge city,” which advocates designing buildings and infrastructure that safely accommodate anticipated massive flooding. 31).Ĭlimate change demands a new sustainable design that addresses serious challenges such as massive storms, earthquakes, and flooding. Further, cities recently completed three megatalls (600+ m) and obviously built none before” ( Al-Kodmany, 2018a, p. Cities also constructed 150 supertalls (300+ m), while they constructed merely 24 supertalls previously. Further, “cities have erected over 1,361 towers with heights that exceed 200 m, while they built only 284 before. In the previous two decades, the world added 12,979 tall buildings (100+ m) to the 7,804 buildings they previously built. Notably, we have seen in the last 20 years, or so an unprecedented, accelerated pace in constructing significant high-rises. However, cities are embracing the tall building typology for additional reasons, including land prices, demographic change, globalization, urban regeneration, agglomeration, land preservation, infrastructure, transportation, international finance, and air right, among others ( Short, 2013 Binder, 2015 Kim and Lee, 2018 Abbood et al., 2021). Indeed, employing high-rise buildings is not the only way to increase urban density. Consequently, to accommodate the influx of urban population while reducing urban sprawl, we must engage the vertical dimension of cities ( Beedle et al., 2007 Al-Kodmany and Ali, 2013 Wood and Henry, 2015). Furthermore, it estimates that by 2100 the urban population will reach about 9 billion inhabitants, doubling today's urban population of 4.5 billion. The United Nations estimates that by 2050 the urban population will increase by about 2.5 billion people, which translates to 80 million dwellers a year, 1.5 million new a week, or 220 thousand a day (The United Nations). As cities cope with rapid urban population growth and attempt to curb urban sprawl, policymakers, and decision-makers are increasingly interested in vertical urbanism.
