In this research work, a sustainable alternative to the consumption of electrical energy generated by a traditional way is proposed, which is highly polluting worldwide, however, part of a deeper problem, since the buildings in which it has been implemented the use of technological systems for the autonomous generation of clean energy "are hidden" from the eyes of man, generally located on the terraces of buildings wasting the great potential of their facades, since they are not designed from the ground up. functional-aesthetic point of view. The application of the NET ZERO ENERGY BUILDING (NZEB) methodology is proposed, through the use of photovoltaic systems that can be integrated in urban environments, designed under architectural conditions that allow them to be used as finishing or facade material in buildings, at the same time that they generate enough electrical energy to cover the demand of the building, obtaining a zero energy balance "0", in this way An overview of this concept is provided for future interventions in similar buildings in the city. This research, for analysis, data collection, and application purposes is focused on a case study in a collective housing building in Azogues, Ecuador.
