BERLI, Marcelo Eduardo; BRONDINO, Agustín  y  DI PAOLO, José. PREDICTION OF THERMAL IMPACT REDUCTION IN A DOUBLE WALL BUILDING. Ingenius [online]. 2018, n.20, pp.38-47. ISSN 1390-860X.  https://doi.org/10.17163/ings.n20.2018.04.

At Santa Fe de la Vera Cruz city, Argentina, a building that includes elements of sustainable architecture, energy efficiency and comfort based on the use of natural resources is built. Particularly, a double facade design on the front walls is meant to achieve an air chamber that prevents heat transfer from the outside to the inside in summer and vice versa in winter. In this work, a numerical study is presented for the evaluation of the thermal performance of a cavity (air chamber) interposed in a double facade of the building for different climatic conditions, considering two air chambers alternatives: connected and non connected to the outside. Both cases are energetically compared with the standard facade design without chamber. The results show that for summer conditions, a chamber connected to the outside would be the most efficient design, while for winter, the closed cavity is the best saving-energy alternative.
