1. Fachadas de alto desempeño
apoyadas en el uso de tecnologías
computacionales
Rodrigo Velasco

3. Computación = Procesamiento de datos
Como diseño computacional se entiende la interrelación ordenada de datos –
variables externas y parámetros de diseño–, para obtener como resultado la
configuración de un modelo de alto desempeño.

4. Procesos
En el diseño de fachadas, este trabajo implica, principalmente, cuatro procesos
computacionales interrelacionados:
Parametrización, Simulación, Optimización y Fabricación.

5. Parametrización
El primer paso en cualquier aplicación de diseño
computacional consiste en estructurar los datos –
parámetros fijos y variables– a ser considerados en
el proceso de diseño.

8. Simulación y optimización
La simulación implica imitar condiciones reales mediante
la ejecución de procedimientos equivalentes dentro de un
entorno virtual .
Al simular el comportamiento de cada una de las
diferentes posibilidades de configuración de diseño –
cambiando los valores de cada parámetro empleado–se
encuentran aquellas con mejor desempeño, este proceso
se denomina optimización

11. Fabricación
Este trabajo de manufactura genéricamente
denominado CNC (Control Numérico
Computacional) implica el traslado de datos
numéricos (dimensiones espaciales) para
controlar máquinas que procesan materiales
mediante corte, troquelado, punzonado y/o
taladrado, entre otros.
