DE GASTINES, Maureen  y  PATTINI, Andrea Elvira. ENERGY PROPERTIES OF WINDOW TECHNOLOGIES IN ARGENTINA. Rev. hábitat sustentable [online]. 2019, vol.9, n.1, pp.46-57. ISSN 0719-0700.  http://dx.doi.org/10.22320/07190700.2019.09.01.04.

Windows significantly impact the energy demand for heating, cooling and lighting in buildings. This study characterizes the energy properties of window technologies available in Argentina by calculating their thermal transmittance (U), solar heat gain coefficient (SHGC) and visible transmittance (VT). Additionally, the impact of different parameters like window opening dimensions, typology, frame material and solar absorptance on the mentioned indices is analyzed. Case studies were selected carefully using cluster analysis methods in order to ensure that the sample examined was representative. The calculation of the U, SHGC and VT indices was carried out using WINDOW 6.3 and THERM 6.3 software. The results indicate that U-values are between 1.88 and 6.00 W/m2K, while SHGC values vary between 0.08 and 0.80, and VT values are between 0.03 and 0.80, depending on frame material, typology and glazing characteristics.
