The transparent units, which constitute the external boundary of the structure, are among the most important factors for its energy performance. This paper presents an analysis of the energy performance of unvented Trombe walls using two of the most commonly encountered types of glazing - single glass and double insulting glass units (IGU). The analyses are based on physical measurements obtained at a test site and numerical simulations of the heat transfer processes in the system. In addition to the energy performance assessment, a thermal load analysis is performed for the more efficient solution, i.e., the double glazed unit, to predict the influence of the occurring heat transfer processes on the mechanical behavior and reliability of the construction.enArticle
