Abstract

Glazed windows have been identified as the thermally weak component in a building and as such heat transmission through glazings has been a subject of interest for research. The authors of this article have been funded by a double- glazing manufacturer to undertake laboratory measurements of thermal transmission characteristics of window systems. CFD techniques have also been employed to characterise the thermal behaviour of these systems. Analysis for glazings filled with gases offering low thermal transmission such as Argon, Krypton and Xenon are provided. Comparison between measured and modelled results is also presented. 1 Introduction The phenomenal development of computers over the past thirty years has fuelled the development of Computational Fluid Dynamics (CFD) to such an
