Abstract
espanolEl presente trabajo tiene por objetivo indagar sobre los consumos energeticos de 17 escuelas localizadas en el Area Metropolitana de San Juan. Se analizan los consumos por ano y por unidad de superficie que permitan obtener una lectura general de la situacion actual. Ademas se realizan analisis estadisticos con el fin de comprender las posibles relaciones entre los consumos energeticos y dos variables arquitectonicas que caracterizan el diseno y la tecnologia constructiva: Area vidriada al norte y K global. Los resultados indican que la energia con mayor participacion anual relativa es la electrica (55%), mientras que el gas natural lo es durante la estacion fria (72%) asociado al abastecimiento de energia en calefaccion. Respecto al consumo por tipo de energia y por unidad de superficie cubierta, los valores son de 26,24 kWh/m2.ano para la electricidad y de 21,80 kWh/m2.ano para el gas natural. El desarrollo de la investigacion permite concluir que existe una importante asociacion entre la envolvente edilicia, tanto opaca como transparente, y el consumo de energia, reconociendo su potencialidad de mejoramiento que se traduzca en optimizacion energetica.
