Abstract
The concept of a vertically stacked city as a model for urban growth in hot climates is examined along with the merits and potential drawbacks of this city form when compared to more conventional horizontally aligned city concepts. Over 90% of new building construction to accommodate the global population growth in the coming 25 years will be in hot climate zones. The construction of new cities might be a more sustainable alternative rather than the expansion of existing ones and in the past 2 decades, over 150 new cities have been launched in more than 40 countries. Against the background of the global goal of achieving carbon neutrality by 2050, the most appropriate currency for comparing the energy performance of various options is land as the ultimate resource. Practical renewable energy supply is a finite resource, as it requires materials and land for its implementation. The concept of energy land, defined as the land area required for the renewable energy production to supply a given urban area, is used to compare future city models supplied by renewable energy sources. Whereas the portion of land taken up by energy production in today’s city is almost negligible, in a vertical city, in which a high-density urban area is powered by renewable energy systems, the land area required for energy production is greater than the land area of the urban development itself. The question considered here is which model - the vertical or horizontal city - leads to higher urban density in a hot climate. Which approach leads to reduced land use in real terms and how do the ecological footprints of the models compare.
