The practical use of low temperature solar thermal systems in buildings consists in using the solar radiation for heating a fluid, usually at temperatures up to 90ÂșC. This facility is carried out with the help of the so-called solar collectors, which make the most of, firstly, the heat absorption and transfer properties of some materials and, secondly, the greenhouse effect produced by some transparent materials, which transmit the shortwave radiation received from the Sun but are opaque to the long wave radiation emitted or reflected by the terrestrial hot bodies. The use of solar energy for some thermal facilities of buildings lets us to decrease the consumption of fossil fuels or electricity, as well as is free of the subsequent greenhouse gas emissions.
