The article presents the results of an analytical study of the functioning of glazing at two different yet interacting levels: at the level of the building as a whole, and at that of glazing as a building element. At the building level, analyses were performed on a sample of high-rise business buildings in Slovenia, where the glazing"s share of the building envelope was calculated, and estimates of the proportion of shade provided by external blinds were made. It is shown that, especially in the case of modern buildings with large proportions of glazing and buildings with no shading devices, careful glazing design is needed, together with a sound knowledge of energy performance. In the second part of the article, the energy balance values relating to selected types of glazing are presented, including solar control glazing. The paper demonstrates the need for a holistic energy approach to glazing problems, as well as how different types of glazing can be methodically compared, thus improving the design of sustainability-orientated buildings.
