What do we mean when we talk about bio-building? What are the advantages of eco-architecture? Is it true that it not only does not limit the comforts we are used to in our homes but also improves well-being and quality of life? How can new eco-compatible housing incorporate specific measures to reduce pollution and consumption/expenses without compromising the comforts we are accustomed to? And above all, is it true that the very model of development of our cities and neighborhoods should be rethought more comprehensively today, as they are too often victims of illegal building, urban decay, and the absence of a serious zoning plan capable of interpreting the buen vivir in protection and respect for citizens?
