Approximately 90 percent of the construction is done with concrete, which provides fire protection. Thus, in a broader sense, underground cities can be effectively protected from fires, earthquakes, hurricanes, high winds, hailstorms, and other natural disasters.
Fremont, CA: Underground building isn't a novel idea. However, with the world population set to expand in the next years and the mounting difficulties of pollution, climate change, and traffic congestion, urban planners have been forced to look underground. Another significant factor is the rise in home prices. In fact, modern science believes that it would have been preferable if ancestors began developing beneath rather than on land - after emerging from caves. The myth that underground houses are dark, stinky, and claustrophobic has also been debunked by modern scientific knowledge.
Surprisingly, there are other factors that make underground living a realistic and profitable alternative in a variety of ways. So, let us go into this intriguing issue and see which towns throughout the world have already begun to construct mini-cities beneath their cities.
Advantages of Building Subterranean Cities
Above all, the most significant benefit of underground construction is energy efficiency. Because the earth's subterranean temperature remains stable, underground dwelling structures can benefit from geothermal mass and heat exchange.
This means that individuals can feel warmer in the winter and cooler in the summer without needing any artificial heating or cooling equipment. When compared to normal living, spending on energy bills might be cut by 80-95 percent as a result of this natural phenomenon. Incorporating a solar design further reduces the bills to zero.
Underground building may appear to be a difficult task. However, studying the ins and outs fully demonstrates that it saves a significant amount of money when compared to land construction. First and foremost, the excavated material can be employed in construction. The need to lay a foundation is completely eliminated, lowering construction and labor costs while speeding up the process. Approximately 90 percent of the construction is done with concrete, which provides fire protection. In a broader sense, underground cities can be effectively protected from fires, earthquakes, hurricanes, high winds, hailstorms, and other natural disasters. When the possible risks are reduced, it is easier to obtain insurance – and at a lower cost. Furthermore, the subsurface buildings require little to no exterior upkeep such as re-painting, which reduces maintenance expenditures.
