This thesis addresses the application of photovoltaic systems integrated to buildings (BIPV). Due to the lack of tools for their design, a methodology which gives the basics for the analysis and simulation of this kind of systems is proposed. For the development of the methodology, factors as commercial products with integration potential, manufacturing of photovoltaic panels, simulation tools with architectonic details of the building and its surroundings, geographical conditions and economic viability were considered. The proposed methodology was validated through a real case in a residential building; the records of generation were contrasted with simulation results, finding similar patterns of energy generation. This analysis allowed to confirm the relevance of the methodology and its potential application in future BIPV projects at local and nation level. Finally, research areas such as construction of photovoltaic panels of specific measures among others, were identified to strength the development in the use of renewable energy.
