Solar thermal systems integrated in the building envelope

Abstract

Buildings were recognized as large energy consumers, and they represent great potential for energy savings through the implementation of a wide range of measures for improving of energy efficiency. Through numerous directives and procedures that have been adopted over the past 30 years, the building sector is committed to the use of renewable energy sources. Among the solutions to the global energy problem, as well as the problem of excessive emissions of greenhouse gases, primarily CO2, which directly affect global warming, the use of solar energy is one of the most acceptable environmental solutions. In the recent years, a new aspect of the application of solar systems in the construction sector has been developed - their integration into the building envelope. This paper presents an overview of the latest research related to solar thermal systems integrated into the building envelope. The current status in the field of technology of solar thermal systems integrated into the building envelope is presented in paper. Different types of these systems that can be integrated into the building envelope are described, and their basic performance is presented. Possible applications of solar thermal collectors in different parts of the building envelope (facade, roof, overhangs, balcony) are also described and presented. By applying these systems, it is possible to significantly influence to the reduction of energy consumption in the building sector, as well as environmental pollution by reducing CO2 emissions.
