Sustainable Cities, Rescue of Original Construction Methods and Use of Technology. A literary Review

The concept of sustainability and even more so applied to the city is quite broad, however in general we could say that they are those whose planning and growth considers current challenges, but also understands and recognizes those next to appear, such as the upsurge of climate change, the growth and migration of the human population in and towards cities, based on which it designs a model based on economic and social development, thinking about the importance of people and their needs. In recent years, several sustainable cities have appeared that are proposed as a model, many of these cities have not only looked to the future with new technologies that offer us efficient systems, but have also looked to the past and have found vernacular architecture of their environments, practical solutions of a passive nature, however, although these model cities can serve as an example and even as a hotbed for the development of techniques and technologies that lead us to a sustainable city, they are not models that can be adapted in an intact way in any territory, but must be reinterpreted to achieve optimal functioning among different conditions of another territory.
