Glass Facade16:20
In this video, we will create the glass façade from Grasshopper and render it in Rhino as rapid prototyping.

Note: The purpose of showing the steps of these models and the changes that need to be made to the initial model during the process is part of the videos. I show all these changes that must be made so that you will be able to face situations such as those seen during the video with your models.
Responsive Facade22:37
In this video, we will create the responsive facade and assign the material to the glass façade.

Sun path as an attractor25:29
During this video, we will locate the facade in Abu Dhabi using the Ladybug plug-in from LadybugTools

We will interact for the first time with the Galapagos interface so that the responsive facade follows the specific time, day, and month. In addition, this date will serve as an attractor for the façade openings.

Explaining Biomorpher13:49
During this video, we will interact for the first time with the Biomorpher plug-in, and we will review its interface so that the responsive facade is according to the specific time, day and month. This date will serve as an attractor for the façade openings.

Description

In this guided project, we will create an Al Bahr type facade where we will make the most of this type of responsive facade through one of the branches of artificial intelligence: Genetic algorithms.

According to wikipedia: a genetic algorithm (GA) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high-quality solutions to optimization and search problems by relying on biologically inspired operators such as mutation, crossover and selection. Genetic algorithms in particular became popular through the work of John Holland in the early 1970s, and particularly his book Adaptation in Natural and Artificial Systems (1975). His work originated with studies of cellular automata, conducted by Holland and his students at the University of Michigan. Holland introduced a formalized framework for predicting the quality of the next generation, known as Holland's Schema Theorem. Research in GAs remained largely theoretical until the mid-1980s, when The First International Conference on Genetic Algorithms was held in Pittsburgh, Pennsylvania.

These will be the topics that we will see during this project:

Create a tower from a polygon and assign glass material for rapid prototyping rendering.
Create a responsive façade and assign materials to these façades.
We will generate an attractor and several point attractors in response to this responsive facade.
Explanation of the genetic and evolutionary algorithms using Galapagos and Biomorpher
We will incorporate the sunshine of a specific place using Ladybug
We will incorporate the annual solar incidence and by specific dates using Ladybug
We will see in greater detail the application of genetic and evolutionary algorithms, taking into account the annual solar incidence to see the response of this facade and review the characteristics that can be modified and maximized using artificial intelligence.

Who this course is for:

Architects or designers focused on parametric design
Architects interested in the use of artificial intelligence (AI) techniques applied to façades
Architects interested in the use of sunlight and solar radiation in façades through AI
