Nowadays, construction is one of the main sectors that produces waste and consume more
materials and energy, so there is a growing need for alternative construction technologies that allow
us to modify this situation. In this context, this paper presents the development of an innovative
proposal for an industrialized outdoor enclosure. This solution is based on a constructive system
with prefabricated insulated sandwich panels, produced on the basis of a new eco-efficient
composite material, based on raw stabilized clay. In this way, it is possible, prioritize environmental
issues to significantly reduce the environmental impact generated during the manufacture of the
piece. The use in the construction of buildings material such as stabilized raw clay can be an
alternative to achieve buildings of nearly zero energy consumption. They are known both from a
thermal comfort and ability to regulate temperature and humidity, as well as being materials that
contain much less embodied energy. This study is a comparative analysis of building systems, as
well, as a serie of selected patent systems and copyrighted materials. On the other hand, it also
analyzes their enforcement against the values established by the Spanish building code
