[en] This paper proposes the development of a passive house under the Passivhaus Standard, whose construction cost is similar to the cost of the same house without the adoption of said construction strategies. The location of the same will be in the city of Hudson, Berazategui party in Buenos Aires, Argentina. For this, the concepts of passive architecture, Passivhaus, almost zero consumption buildings, and renewable energies were studied together with the regulations of thermal and energy performance in construction in Argentina. The necessary technologies were analyzed to be able to apply this objective in the country, taking into account economic conditions, technological developments and local regulations regarding the generation of renewable energy and thermal conditioning of buildings. A single-family home project with photovoltaic installation was developed applying the criteria studied above and finally the comparison between the material costs resulting from the application of the principles of the Passivhaus standard and the costs without the application of said principles was made, following the local regulations. It was possible to verify the possibility of applying the Passivhaus criteria and Almost Null Consumption Buildings in the construction of a house in Buenos Aires whose difference in relation to the economic costs in terms of materials is approximately 30% more than the housing according to local regulations. The possibility of projecting a house under the Passive House Plus certification was verified. However, on-site renewable energy generation fell short of meeting demand targets for off-grid operation.

[gl] Este traballo propón o desenvolvemento dunha casa pasiva baixo o estándar Passivhaus, cuxo custo de construción é similar ao custo da mesma casa sen a adopción das devanditas estratexias de construción. A localización do mesmo será na cidade de Hudson, partido Berazategui en Bos Aires, Arxentina. Para iso estudáronse os conceptos de arquitectura pasiva, Passivhaus, edificios de consumo case cero e enerxías renovables xunto coa normativa de rendemento térmico e enerxético na construción en Arxentina. Analizáronse as tecnoloxías necesarias para poder aplicar este obxectivo no país, tendo en conta as condicións económicas, a evolución tecnolóxica e a normativa local en materia de xeración de enerxías renovables e acondicionamento térmico de edificios. Desenvolveuse un proxecto de vivenda unifamiliar con instalación fotovoltaica aplicando os criterios anteriormente estudados e finalmente realizouse a comparación entre os custos materiais derivados da aplicación dos principios da norma Passivhaus e os custos sen a aplicación dos devanditos principios, seguindo a normativa local. Púidose comprobar a posibilidade de aplicar os criterios Passivhaus e Edificios de Consumo Case Nulo na construción dunha vivenda en Bos Aires cuxa diferenza en relación aos custos económicos en materia de materiais é aproximadamente un 30% máis que a vivenda segundo a normativa local. Verificouse a posibilidade de proxectar unha vivenda baixo a certificación Passive House Plus. Non obstante, a xeración de enerxía renovable in situ non acadou os obxectivos de demanda para a operación fóra da rede.
