Abstract: A massive 0,52 m thick wall was used for the research. The external area of this wall is 11 m2, it is painted in heat resistant black paint and covered with transparent polycarbonate 0,01 m thick cover. Two holes (one on the top, another on a bottom) are made. These holes allows the air to move by forcing it’s circulation. While the air is moving in a forced manner it gets into the premises through the bottom whole and comes back through the hole on the top into the space between transparent cover and the wall painted in black. Such movement of air reduces loss of thermal energy through the wooden frame of transparent cover and other leakages. The main parameter of a massive wall is it’s average daily coefficient of efficiency. As a result of the research the average daily coefficient of efficiency is 0,76
