Abstract

Continuing demand for tightening of building regulations with respect to energy efficiency has led to the increased use of double-glazed windows. However, even with the use of low emissivity coatings and inert gas infill the glass window is by far the thermally weak element in the buildings' fabric. In the present article measurements and modelling techniques have been used to study the longitudinal temperature variation along the inward facing glass pane of a double-glazed window. It has been shown herein that the above temperature variation is primarily due to the buoyancy driven flow of gas within the sealed enclosure which alternates between the heated inward and cooled outward panes. This work will be a prerequisite for quantification of the co
