Climate change, the constant growth of energy consumption, and the high levels of emissions recorded by the energy sector, require the implementation of concrete solutions. Building rehabilitation offers a significant opportunity to contribute in this regard. The purpose of this work is to analyze the potential for intervention in a school building from the “Programa Nacional 700 Escuela” (National 700 Schools Program). The improvements in energy efficiency are evaluated through a dynamic simulation and indicators are calculated regarding the annual energy consumption for heating. The values for the reference building are 74.5 kWh/m2 year and 158 kWh/student. With the rehabilitation proposals, energy savings could be achieved of between 39.7% and 60%. The R-Mean alternative appears as the most convenient one as it achieves energy benefits of 47%, with lower investment costs. The energy efficiency indicators for said set of improvements are 39.2 kWh/m2 year and 83.1 kWh/student. The results achieved can serve as reference for the rehabilitation of 71 school buildings built in the province of San Juan between 2004 and 2015, which belong to a construction typology with a similarity of materials of their envelope and functional configuration.
Resumen Se estudia el comportamiento térmico-energético de una vivienda social en la región central de Argentina. El objetivo es evaluar energéticamente la vivienda para un período histórico entre 1960 y 2011 y obtener el modelo termo físico a través de la simulación con ECOTECT y SIMEDIF para proponer su rehabilitación. La disponibilidad de datos reales del consumo de energía permitió la calibración a través de la simulación y la obtención del modelo, base de la rehabilitación orientada a la conservación y a la solarización a través de la incorporación de aislación térmica en la envolvente y un aumento del 10,8% al 20,3% del área vidriada colectora al norte. Los resultados muestran que la rehabilitación energética permite, además de satisfacer las recomendaciones de las Normas IRAM, mejorar el nivel del etiquetado energético con ambientes térmicamente confortables. A partir de la intervención energética la energía contenida se incrementa un 4,3 y un 7,1 % para alcanzar el Nivel B y A de la Norma IRAM, respectivamente con un ahorro de energía del 53,7 y del 85,6% en la calefacción (H) de los espacios. El consumo anual por metro cuadrado de superficie útil es de 34,9 kWh/m2, valor auspicioso aún no pudiendo alcanzar el Nivel Passivehouse.
