In an architectural era, modernism and minimal architectural designs ruled the world. Linear forms, seamless fenestrations, sleek glass, and minimalistic concrete forms formed the architecture palette across the globe. Every nation wanted to sport tall, sleek glass, steel, and concrete structures. Thus, establishing their identities as “modern.” After all, architecture has always been a visual medium for communication. Therefore, with time and technology, contemporary styles have taken the stage. The advancements in design ideologies, technology, and innovation have led to an influx of free-flowing geometric forms into the AEC industry. There is a tremendous increase in the trend for convoluted geometries in building technology. Thus paving the way for parametric forms, abstract shapes, and humungous scales for buildings. This article aims to showcase a list of the top 10 Grasshopper plugins mostly used in the AEC industry.

The influx of Parametric Architecture

There is an upward trend in the design realm to play around with forms showcasing material strength, flexibility, and innovation in construction technology. But are the traditional design tools feasible to turn the vision of a parametric wonder into reality? Can conventional computer-aided software handle innumerable data? Can it cater to the new-age techniques implemented in the design?

No! the new-age designs require new-age tools. The need of the hour is to induce parametric design techniques and tools that aid in designing abstract forms and geometries. Grasshopper is one tool that aids in designing parametric forms with complex curves and surfaces. Moreover, Grasshopper not only automates the design process but also is handy to use and minimizes the time required to formulate designs.

Generally, it is used for advanced design processes. This includes creating, analyzing, modifying, and presenting the design. The accuracy, quality, and ability to administer makes Grasshopper among the most sought-after tools for architects in today’s world.

Thus, along with the grasshopper as a tool, designers also need to know the associated high-performing plugins that make tasks efficient and better in the software.

Here’s a list of the top 10 Grasshopper plugins that are trending in the AEC industry:

1. Ladybug 

“Ladybug” is an open-source parametric plugin that aids environmental analysis within the Rhinoceros/Grasshopper Interface. It functions by importing standard “Energy Plus Weather” files (.EPW) into Grasshopper 3D. This tool consists of a wide variety of 2D and 3D interactive graphics, which helps the users to conduct environmental studies accurately for the form generation of the structure. While Ladybug simplifies the analysis, it also automates the calculations. Thus, providing accessible and legible graphical visualizations in the interface of Grasshopper.

Furthermore, It also facilitates working with validated energy and daylighting engines such as “EnergyPlus”, “Radiance” and “Days”, effectively. The Ladybug Plugin thus helps architects to gauge the system and make efficient design choices.

3. Geco

Among the vast number of Grasshopper plugins, Geco is an environmental analysis used widely by designers. It facilitates users to export and collaborate efficiently with Ecotect’s associated software. Therefore, this system helps evaluate one’s design by comparing it with various performance data. Again this data can be imported to Geco as feedback into Grasshopper.

Moreover, Ecotect is visual software that enables designers to test environmental performance issues and simulate the various environmental and climatic conditions. Thus, combining Geco and Ecotect leads to designing parametric structures, making them sustainable and efficient.

4. Heliotrope-Solar

Heliotrope-Solar is a Grasshopper plugin that helps manipulate geometric forms based on the dynamic sun path. The tool uses vector physics to calculate the sun’s apparent position on specified days at specific times. The plugin then uses this data to compute and provide a variety of components for shaping the design parametrically based on analyzed data.

Thus, Heliotrope-Solar helps create solar-aware designs. As a result, it helps deduce the position of rendering lights & design shading devices in the design. One noteworthy fact is that the usage of this plugin can be extended to generate climate-responsive designs where the building envelope adapts to the natural systems and performs in response to the dynamic movement of the sun.
