In France, Felix Trombe and Jacques Michel developed a method of combining a glass-assembled solar wall with a heat accumulator, and obtained a patent for a special Lomb wall named after the researcher, and in 1967, at latitude 43.5 & #186; The house that is too slow is built in Audureau. Trombe with patent? Michel wall is a glass wall installed in front of a concrete wall, with a thickness of 600mm and a glass thickness of 1 20 mm. In winter, the openings at the top and bottom of the wall allow warm air to enter, and in summer, the assembled glass is opened at the top to let the sun heat flow away, as shown in the following figure:1.

To some extent, the structure of Lomb wall has already predicted the appearance of modern double-layer external wall.
