Computational Design And Generative Architecture

Since the development of computers, people have become more adept at multitasking and multitasking calculations. The internet has brought the entire world to our fingertips in the twenty-first century. Computational design refers to the use of computers and certain algorithms, which has had a considerable impact on architecture. We can use a mathematical technique to generate complicated geometry through computational design, allowing us to play with different options through parameters and constraints. Computational design has helped architecture reach a new level in the modern era of computational architecture, and that is what makes it such an invaluable addition to the architectural field.

Put in the most basic of terms, computational design is the future of architecture. Mastering and understanding this technique means having access to resources that so many others do not have, and being able to go to lengths that other people have not been able to get to. It means having the opportunity to turn even the most abstract vision of a design concept, into reality. Even the demand for professionals who can design in this peculiar way is already on the rise, and will multiply in the years to come.

Emphasis must be laid on the many reasons why computational design is very important in modern day architecture. It offers the opportunity to designers to unleash their creativity, and bring even the most abstract concepts to life. Every architect has gotten to that point at one point or the other, where there is a very vivid design idea stuck in their head, yet they somehow lack the ability to translate it into viable projects due to structural or environmental factors. Other times, they are unable to find the optimal design response to certain constraints and draw backs, and it may even keep them from proceeding with the design.

However, with computational design in architecture, that does not have to be a problem anymore as it develops design solutions based on the specific parameters that have been specified, turning what seemed impossible into a feasible design.

Generative architecture is a design exploration process that allows the design to truly explore as many possible versions of itself that there are. By inputting their design goals into a software alongside the specific parameters for the design, architects can watch the AI generate several alternative versions of the design and tests them to see which works best.

Generative Architecture is a branch of computational design that enables architects to discover novel design concepts that they may never have been able to come up with on their own. Basically, it is the future of architecture.

Computational Design

Computational design uses a combination of factors and methods to solve design problems utilizing complex computer processing. A designer's workflow is broken down into discrete computer-coded steps. This data is used by the software to develop algorithms that produce design models or comprehensive design studies, together with project-specific parameters. As soon as the first programming is finished, design becomes a dynamic and repeatable process.

Traditionally, a designer employs a computer-aided design (CAD) application along with their knowledge and intuition to develop designs. The number of design possibilities that may be taken into account with this hand drafting process is constrained by the amount of time and resources that are available. Once put into practice, computational design is a powerful and practical technique for boosting output and producing more durable designs.

To use computational design, designers must divide their design process into manageable parts. These actions produce a set of guidelines that serve as the building blocks for algorithms to solve design problems. They also produce patterns and trends that can be easily recognized.

Softwares Used For Computational Design

Designers may use programming power without having to learn code thanks to computational design. This is because most computational design tools don't use lines of text-based code, but rather visual programming. In visual programming, users link the outputs of one node to its inputs to build a program that moves between nodes via connectors. The outcome is a flowchart, or a graphic representation, of the design process.

These visual programming tools are often add-ons that work with design modeling programs like Bentley MicroStation, Autodesk Revit, Trimble Quadri, and Tekla Structures. Dynamo, which works with Revit, and Grasshopper, which works with Tekla, Quadri, and Rhino, are two of the top computational design plug-ins.

Grasshopper is the most widely used computational design plug-in and precedes Dynamo. The node-based interface of this algorithmic modeling tool allows users to construct design guidelines. The vast node library plus third-party design tools are also available to designers.

Components of Computational Design

As industry standards are developed, computational design is always changing and evolving. Below is a list of the three categories of computational design that exist today.

1. Parametric Design

2. Generative Design

3. Algorithmic Design

4. Parametric Design

An interactive design technique called parametric design employs a set of rules and inputted parameters to regulate a design model. The rules define the connections between various design components. The design model’s parameters such as its dimensions, angles, and weights, are project-specific values. Based on the defined dependencies, algorithms automatically update all related design elements whenever a parameter is changed.

Parametric design is already a common part of many designers' workflows. Parametric design is possible with Rhinoceros 6's built-in visualization tools, like Grasshopper, and visual programming is straightforward. Designers only need to input the relevant design criteria together with characteristics like dimensions, angles, or offsets in order to obtain a result. When attributes are changed, the parametric design process, which is done in a real-time BIM program, automatically updates.

Generative Design

An iterative design technique called generative design employs user-defined inputs to generate a variety of design concepts that adhere to predetermined objectives. Similar to parametric design, the inputs are sets of rules and parameters that specify the needs for the design. The user also enters success measures that will be used to assess the outcomes in generative design. These criteria enable artificial intelligence (AI) and cloud computing to produce tens or even hundreds of design possibilities.

Success criteria include elements like building placement, spatial planning, life safety analysis, structural loading capability, number of building units, and cost information. The software will generate a large number of design choices, and the designer will adjust the optimization criteria in accordance with those options.

When given free rein, designers frequently produce predictable outcomes. Although there will always be some trial and error involved in design, it is impossible for a human to generate and evaluate every design possibility. As a result, sometimes instead of choosing the best alternative, architects rely on tried-and-true designs or those employed on prior projects.

Design professionals that use generative methods discover answers that go beyond their typical line of thought. The term "happy accidents" is used to describe these solutions in the generative design community. Optioneering is the process through which designers carefully investigate a variety of design choices in order to analyze all results, hone their criteria, and select the optimal design solution.

Design optimization is accomplished using generative design. These tools are used by designers to increase the number of locations served by a road, reduce the number of structural members required to support a certain design load, or reach a predetermined thermal capacity that depends on a variety of building surfaces or materials.

Stages of Generative Architecture Design

Pre-Generative Design

The initial or preliminary stage is known as pre-generative design (Pre-GD). Now you must specify limitations, establish goals, and pinpoint essential elements for achieving them. The primary collection of information used to start the generative design process consists of these data. The more precise the data gathered and entered into the generative process, the more effective and well-tuned the results will be.

Generative Design

Computer algorithms are used at the second step, sometimes known as the major stage. After receiving the data, it begins a cyclical process known as generative design (GD), which itself may be broken down into three steps.

To create

The computer program generates a range of designs utilizing a seed provided by the human operator and the specified parameters.

Analyze

The results are analyzed by the computer, which also determines whether they comply with the initial requirements.

To develop

Based on which option among those under consideration is the most compatible, the algorithm chooses the direction of a new cycle of design, utilizing that choice as a new seed to start the process all over again.

Post-Generative Design

At this point, the process has produced a final set of proposed designs that the designer and other interested parties can review and select from. Afterward, the architects and other experts can manually develop and refine the option that was selected further while making sure that all.

Benefits of Computational Design

Creating Effective Solutions 

Designers can consider far more design alternatives than the limited number they could with manual drafting. They can also benefit from the original design ideas produced that deviate from accepted wisdom. Algorithms for design can be improved to produce better results over time.

Automate Repetitive Tasks

Changing a dimension or a surface is easy when it only affects one element, but when it affects hundreds of elements, it becomes laborious and less profitable. A designer can construct an algorithm that changes the entire model in real-time using computational design tools linked to modeling software.

Enhance Productivity

Once company-specific design processes have been incorporated into computational tools, designers can essentially delegate design tasks to these programs. Architects may produce designs more rapidly and with fewer iterations by using computational design, which boosts productivity and makes better use of resources.

Reduce Design Risks 

A designer can enhance design quality beyond what is possible with human ability by using iterative design methods and simple visual programming tools. One can use artificial intelligence to test a design in various situations. All parties’ risk and liability are reduced by error-free designs.

Lower Project Costs

The amount of employees required for a project can be decreased by using computational design tools to handle time-consuming design chores and design thinking. Additionally, designs generated by algorithms will contain fewer faults, decreasing the possibility of design revisions in the field.

Importance of Computational Design in Construction

Optimized Equipment Positioning 

The availability and transfer of necessary construction equipment determines the entire timetable for some construction projects. Generative design enables contractors to acquire project-specific ideal data to decide the best quantity and location of tower cranes and other significant pieces of equipment.

Reduced Material Waste 

The goal of any project is to produce zero waste, or at the very least, to produce as little waste as possible. However, this is easier said than done. Utilizing generated waste evaluations and raw material data, computational techniques could be used to optimize a project design to decrease waste.

Better Order of Operations 

The ability to stack and arrange trades is a difficult task that can make or break a project's schedule. Computational design tools enable a project team to create logic that coordinates the installation of construction components.
