 Trombe walls are often designed to serve as a load-bearing function as well as to collect and store the sun’s energy and to help enclose the building’s interior spaces.The requirements of a Trombe Wall are glazing areas faced toward the Equator for maximum winter solar gain and a thermal mass, located 4 inches or more directly behind the glass, which serves for heat storage and distribution.Also, there are many factors, such as color, thickness, or additional thermal control devices that have an impact on the design and the effectiveness of Trombe Walls.
