          Abstract

          El ahorro de energía es un tema muy de actualidad en Chile. En el sector de la construcción hay dos frentes divergentes: por un lado, el confort interior insuficiente y por otro, el alto consumo energético, ambos son producto de una edificación deficiente. En este artículo, se demuestra que en el centro-sur de Chile, se puede ahorrar aproximadamente un 80% de energía en climatización con construcciones que cumplen con el estándar energético, llamado estándar "Passivhaus". Junto con la posibilidad de bajar la demanda energética, se aumenta también el confort interior. A través de un estudio paramétrico, se analizaron las distintas configuraciones necesarias para cumplir con el estándar, en tres ciudades del centro-sur de Chile. La tecnología para construir casas "Passivhaus", tales como, una alta aislación térmica, las ventanas termo paneles Low-E con argón o, los sistemas de ventilación con recuperación de calor, ya son accesibles en el mercado nacional. Sin duda, las construcciones que logran el estándar "Passivhaus" tienen un costo de inversión inicial más alto que una construcción tradicional, pero, por otro lado, una casa "Passivhaus" tiene un costo de operación aproximadamente de un 80% más bajo que una vivienda tradicional. Con este ahorro en los costos de la operación, se recupera el costo inicial más alto, durante la vida útil de la construcción.

          Translated abstract

          Energy saving is a very actual topic in Chile. There are two divergent realities in the construction sector: on the one hand an inadequate indoor comfort and on the other hand, very high energy consumption. Both are products of a low building quality. This article shows that it is possible to save about 80% of energy in space heating and cooling in the central-south area of Chile, with low energy buildings which reach the so-called Passive House Standard. Using this standard not only reduces the energy demand of buildings but also increases its internal comfort conditions. A parametric study was utilized in order to analyze, by what means it is possible to meet the standard in three cities in central-south of Chile. The technologies to build Passive Houses, such as high thermal insulation, double glazing windows with Low-E coating and argon filling or ventilation systems with heat recovery are already available in the market. Without doubt, the buildings that achieve the Passive House standard have an higher initial investment cost than a traditional building, but on the other hand, a Passive House has approximately 80% lower running costs than a traditional building. Due to this saving in operating costs, it is possible to economize the higher initial cost during the lifetime of the construction.
