          Abstract

          El sector residencial presenta un creciente consumo energético, y las condiciones de forma han sido sugeridas como uno de los aspectos más incidentes en el comportamiento ambiental de las edificaciones. La zona centro-sur de Chile presenta un predominio de viviendas unifamiliares con volumetrías independientes, que podrían tener una influencia relevante en su desempeño energético. Con el fin de esclarecer la incidencia de características formales en el comportamiento ambiental de esta tipología este artículo expone una revisión de varios estudios y de las principales condiciones de las viviendas en la zona, y luego un análisis mediante simulaciones energéticas de un modelo de diferentes configuraciones con la misma superficie y características constructivas. Identificando una influencia relevante de la variación, contigüidad y altura en la demanda energética, con una escasa incidencia de la orientación solar. Al final se sugiere un factor de regulación, correspondiente a la superficie de muros expuestos, lo que expresa su relevancia formal y material, y puede ser implementado para fomentar la reducción del gasto energético y mejoramiento ambiental de las viviendas en la zona.

          Translated abstract

          The energy consumption of the residential sector has been increasing and the formconditions have been suggested as one of the critical aspects in the environmental behavior of dwellings. In central-south Chile, there is a predominance of single-family housing with independent volumetrics, which may have a considerable effect on their energy performance. In order to clarify the effect of formal characteristics on the environmental behavior of this typology, the paper reviewsseveral studies and the main conditions of dwellings in the area, followed by an analysis based on energy simulations of a model with different configurations with the same surface and constructional properties. The analysis results enable the identification of an important influence on the variation, contiguity and height of energy demand, with low impact of solar orientation. The conclusions suggest a regulatory factor corresponding to the surface of exposed walls, which is expressed on their formal and material importance; such a factor may be implemented to promote the energy consumption reduction and the environmental improvement of dwellings in the area.
