Facade and protection
The most basic and even in terms of age, the first task that Nama was responsible for was protection. In order to protect themselves from weather and climatic factors, humans created a space called house for themselves. The lack of openings in the building prevented the wind, rain, heat and cold, but deprived the building of the necessary light and ventilation. As the need for these gifts increased, the need to create an opening in the wall of the building increased, and as a result, the need for another shell called the facade for more protection arose.
Insulation to the cold, heat
Different building materials have different heat transfer coefficient and specific heat capacity, and as a result, they will have different thermal performance. A successful facade system is a facade that has both beauty and energy efficiency. Having a facade that has good thermal performance directly affects energy consumption, therefore, the use of materials with a lower thermal transfer coefficient should be considered in the facade of the building.
Insulation
The facade of the building can act as an ideal sound insulation. Paying attention to this feature is especially important for buildings located in large industrial and commercial cities or next to the main thoroughfare.
- Earthquake resistance
- Impact resistance - Resistance to freezing
- Resistance to fire
- Resistance to falling
- Flexibility in facade execution
- Lightness
- Applicability in high-rise buildings
Facade as an interface
The facade of the building should be designed in such a way that, despite the protection of the inside environment from the outside, it establishes the connection of the outside space with the inside environment of the building well. For example, it is possible to shine light inside or to use the view outside.
Facade as a reagent
Just as a person's clothes represent his personality, the house should also represent the personality and social status of its owner, just like the second clothes. In the western architecture, it has a mode of display, so that it shows the person who lives behind it in the first place. In fact, the facade represents the family character and social class of the owner. In addition to introducing the personality of the owner, the facade also represents the location of the property and the type of use of the building.
Beauty
Façade is the external appearance of every building and it is not a hidden cover away from public expectation. The facade is always noticed by the public, so beauty is an integral part of every facade. Also, the beauty and style of the facade represents the art and quality of the work of the architect and designer.
Building facade
The appearance of each residential unit is different depending on the environmental conditions such as weather, wind and storm, earthquake and the amount of air pollutants in different areas. The materials used in the facades of large and industrial cities that have high pollution are different compared to the materials used for the facades of small cities that have clean air. Also, the facade of the building in cold regions is different from the usable facade in tropical regions in terms of the degree of resistance against freezing or insulation against cold and heat.
