Abstract: A prefabricated wall panel defines a panel plane and a peripheral edge includes a plurality of material layers parallel to the panel plane and superimposed on one another, including a load-bearing layer made of reinforced cement, a protective layer distanced from the load-bearing layer, and a heat-insulating layer formed on a side of the load-bearing layer opposite to the protective layer. An air circulation gap is formed between two layers of the material layers so as to separate the two layers from each other. The air circulation gap is open on the entire peripheral edge. A plurality of spacer connectors extends in a direction transversal to the panel plane through the air circulation gap, each spacer connector having a first anchoring end fixed in the protective layer and a second anchoring end fixed in the load-bearing layer.

Abstract: Brick material building element and method of building with the element, wherein the brick material building element includes a base having a length, a first side, a second side, an inner surface, and an outer surface, whereby a width is defined by a distance between the first side and the second side. A longitudinal protrusion is formed on the first side of the base. A longitudinal recess is formed on the second side of the base. A main protrusion extends from the base. The main protrusion has a surface which is shorter than the length of the base. At least one longitudinal through opening is disposed in at least one of the base and the main protrusion. The longitudinal protrusion includes an external shape which is complementary to and adapted to fit within the longitudinal recess of another brick material building element.
