Use of Transparent Insulation Materials as One of the Measures of Improving Energy of Structures

Abstract

Structures can be repaired in several ways: physically, economically or in terms of their energy consumption. When talking about energy efficiency, buildings are certainly repaired in terms of their energy saving capacity, provided that there is a need for it. The energy saving aspect of reparation is reflected in the rationalization of their energy consumption, preservation of their engineering substance, improving their thermal comfort, as well as in the use of renewable energy sources. In terms of thermal comfort, one of the traditional building reparation methods is improving the thermal properties of sheathing by using transparent insulation materials. Depending on the purpose of the structure, it is often necessary to use transparent insulation. Heat flows through these materials that are part of the structure’s thermal mass are calculated specifically according to regulations on energy efficiency of structures applied in our country. These thermal insulations are belonging to the group of newer materials. This paper provides an overview of transparent insulation materials, along with the opportunities they are offering regarding the improvements of energy efficiency of heating, i.e. improvements in the buildings’ thermal comfort, with the minimum use of primary energy.
