Resumen
El sector edilicio es responsable del 40% de la demanda energética a nivel internacional y el 37% en Argentina. La climatización constituye el ítem más representativo. Los países instituyen medidas para el uso racional de la energía y persiguen estrategias a fin de provocar la transición energética. La aprobación del estándar IRAM 11900 en Argentina promueve la Eficiencia Energética (EE) en el sector edilicio residencial que se pretende, sea inclusivo y conduzca a la transición al 2050. El objetivo del trabajo es la evaluación termo-energética de un prototipo existente de vivienda de interés social del Barrio Papa Francisco y sus variantes mejoradas “retrofit” y “ex ante”, desde el enfoque de la norma. Para ello se relevan dimensiones, sistemas constructivos, componentes de la envolvente y equipamiento para cubrir demandas de calefacción, refrigeración, agua caliente sanitaria e iluminación. Como resultado relevante, el índice de prestaciones energéticas (IPE) del prototipo existente alcanza un valor de 132 kWhPrim./m2.año. Además, las variantes mejoradas “retrofit” y “ex ante” conducen a ahorros económicos considerables en la inversión inicial. De aquí que se valora la importancia de implementar software de análisis en la etapa de proyecto para cuantificar los recursos energéticos y el ahorro de emisiones en una transición energética planificada.
The building sector is responsible for 40% of the energy demand internationally, and for 37% in Argentina. Heating and cooling are the most representative item. Rational energy usage measures are being introduced in countries throughout the world, as well as strategies that pursue energy transition. The passing of the IRAM 11900 standard in Argentina promotes energy efficiency (EE) in the residential building sector, and it is expected to be inclusive and lead to the transition by 2050. The aim of this work is to perform the thermo-energy evaluation of an existing social dwelling prototype in “Barrio Papa Francisco” (Pope Francisco Neighborhood), as well as in its two improved variations: “retrofit” and “ex ante”. For this, information is collected about the dimensions, construction systems, building envelope components and equipment to meet demands for heating, cooling, domestic hot water and lighting. As a relevant result, it is reported that the energy supply index (IPE, in Spanish) of the existing prototype reaches a value of 132 kWhPrim./m2 .year. In addition, the retrofit and ex ante variations lead to considerable economic savings in the initial investment. This is why the importance of implementing software analysis at the design stage is considered as important in order to quantify energy resources and emissions savings in a planned energy transition.
