2 Ways to be truthful:

1. Terms of program

2. Terms of construction.

MATERIALS

In the process of evolution, materials and technology are replaced by new ones, but the shapes remain alive and active.

Different materials:

Stone: A lot of kinds (sandstone, limestone, granite, marble, slate) Ashlars…

Earth: Most constructions employed in trditional architecture are made of earth as it is easy to found.

2 ways of using it:

Tapia: each of the pieces of wall that are made at one time with rammed earth and lime into a formwork.

Adobes: sun-dried clay blocks. May contain reinforcing straw. Usually use a mortar very similar to clay.

Bricks: Few mudejar castles made of bricks.
A bricks is a fired clay block.Brick is very good at compression but very good at tension.

Wood: Okurari technique.

Steel: The Ancient Colon Market made of steel. Another buildings or monuments such as the Atomium.

Concrete: A material that allow a lot of posibilities. It can be used in mass or very thin layers. It has not previous form. you give the form you want.

Glass: Revolution in 19th century. Crystal Palace.

TECHNOLOGY

ROMAN CONSTRUCTION is defined as the result of an extraordinary availability of materials and workmanship. The basic material in Roman construction is concrete.
ROMANESQUE ARCHITECTURE built the roof with BARREL VAULT reinforced by TRANSVERSE ARCHES.

GOTHIC ARCHITECTURE ends up definitively solving the problem thanks to:
• the pointed arch
• the rib vault
• the buttress
• the flying buttress

• the pinnacles.

The difference between Classical and Gothic architecture is that the first is passive, merely channels and absorbs forces, while the second is dynamic.

Modern Technology:

• Computer Aided Design (CAD)
• Building Information Modeling (BIM).
• The difference between Classical and Gothic architecture is that the first is passive, merely channels and absorbs forces, while the second is dynamic.
  
  Prefabrication:

• Cross Laminated Timber (CLT) pannels
• Glassfibre Reinforced Concrete/Cement (GRC) panels.
• Prefabricated rammed earth blocks

STRUCTURES

New Challenges:

-Express the stability and instability as aesthetic principle:

Cantilevers;

-Structure dissolution with new materials and structural types. Dematerialization.

FACILITIES

Building facilities are infrastructures formed by networks and fixed equipment that enable the supply and operation of services that allow functionality, efficiency and comfort in those for which they have been designed.

Hydraulic facilities

Energy networks

Climatic installations

Telecommunications

Medical Installations
