Here are reviewed the ways of fabrication of ecologically-safe structures of wall elements, intended for the construction of active-energy walls. In the structure of these wall elements in a suitable way is integrated a pipeline for solar heating. The basic advantage of these structures is the separate mounting and dismounting of the structure layers and the integrated pipeline elements. In case of wearing-out or expiry of the exploitation term of the structure layers, the elements of the pipeline could be separately collected and stored in depots according to the building material.
