The word facade originally comes from the Italian word “facciata”, and is defined as the front face of a house. Along with the roof, it is one of the most important elements of a building, since it acts as the primary barrier against external weather elements that could damage the health of the structure, such as rain, snow, wind, frosts, sun, etc. In the case of architecture, facade refers to the exterior side of the building, usually the front. A building facade is important because it is a chance to put the emphasis on design. As well as being aesthetically pleasing, a building façade also plays an important role in energy efficiency as well as linking the exterior building design to the interior design.
