Why Parametric Landscape Design is the Next Big Thing in Landscape Architecture?

The idea of “creative thinking” has gotten a new dimension with the advent of parametric modelling and design. Parametricism has established itself as the modern-day methodology of design conceptualisation, helping redefine what’s possible with technology in the built environment. 

What is Parametric Modeling and Design?

Parametric modelling is a computational design approach that involves creating 3D models by defining parameters and establishing relationships between them.

Further simplifying the concept, parameters are adjustable variables such as dimensions and angles that can be linked through algorithms, forming a set of rules that dictate the model’s behaviour. This process is completed through parametric modelling software such as Dynamo, Revit, Grasshopper, and Rhino. These software provide a comprehensive platform for defining, manipulating, and visualising building components to be composed as functional parametric designs.

What are the Benefits of Parametric Modelling and Design?

Parametric design architecture is shaping the buildings and infrastructure of tomorrow. But is there a way to derive real-world benefits from this new style of architecture? Below is a list of some features that show the importance of parametric design in modern architecture.

1. Design Exploration

Parametric modelling fosters a non-linear design process, encouraging architects to explore innovative and complex forms that might be challenging with traditional methods. Using algorithms and parameters often allows them to create intricate structures and patterns that respond to specific stimuli, advancing the design process into a new era of possibilities.

2. Optimised Performance

Architects and designers use parametric design to analyse and adjust parameters, allowing for the optimisation of structures based on performance criteria. These parameters include criteria like energy efficiency and structural integrity. This gives professionals a sense of control over the project.

3. Enhanced Collaboration

Parametric modelling and design also facilitate collaboration among architects, civil engineers, and other stakeholders. Parametric tools offer a shared platform for real-time design modifications. This enhances stakeholder communication while contributing to the ease of coordination in complex building systems.

4. Sustainable Solutions

Parametric modelling aids in the creation of environmentally conscious designs by enabling architects to simulate and optimise for factors such as sunlight exposure, wind flow, and thermal performance. This predictive capability enables them to make informed decisions that contribute to energy efficiency and environmental sustainability.

5. Time and Cost Savings

The efficiency of parametric design can aid significant time and cost savings throughout the design and development phases. Rapid iterations, coupled with the ability to analyse performance and optimise designs, contribute to more streamlined and economical project timelines.

What is Landscape Architecture and Design?

Landscape architecture is a multidisciplinary design field that combines elements of art, design, environmental science, and urban planning to create visually appealing, highly functional, and sustainable outdoor spaces. Some key examples of outdoor spaces include arenas, squares, parks, playgrounds, urban plazas, and waterfronts.

The professionals who design these places are called landscape architects. Their work goes beyond aesthetics and encompasses considerations like ecological sustainability, environmental conservation, and the enhancement of the quality of life for individuals and communities. They collaborate with other professionals, stakeholders, and clients to ideate and implement designs that harmonise with the natural surroundings while meeting the diverse needs of users.

What are the Applications of Parametric Design in Landscape Architecture?

Through the lens of parametricism, outdoor spaces are canvases for dynamic transformation, allowing architects to sculpt landscapes with precision and purpose. Let us look at the five key applications of parametric design in landscape architecture.

1. Site Analysis and Planning

Parametric landscape design allows professionals to conduct a comprehensive site analysis by integrating geographical, climatic, and topographic data. The dynamic adjustment of parameters facilitates the optimisation of land use, ensuring that the landscape design is not only visually appealing but also responsive to the unique characteristics of each site. This includes factors such as sun exposure, wind patterns, and soil conditions, optimising the placement of elements like seating areas, pathways, and vegetation.

2. Creating Dynamic Structures

Landscape architecture involves planning and designing structures like pergolas, gazebos, and shaded walkways. By using parametric landscape design, architects can explore new structural forms, materials, and construction techniques to develop engaging designs. This helps in the realisation of complex geometries which are otherwise difficult to achieve. More so, parametric modelling helps devise pedestrian movement patterns to curate circulation pathways.

3. Generative Planting Design

Parametric tools enable generative design approaches for planting schemes. Algorithms can be employed to explore and generate diverse combinations of plant species based on ecological compatibility, aesthetics, and functional requirements. This promotes biodiversity within the landscape, creating resilient ecosystems that are not only visually appealing but also contribute to environmental sustainability.

4. Microclimate Optimisation

The precision afforded by parametric landscape design tools extends to the optimisation of microclimates within outdoor spaces. By meticulous analysis of wind patterns, sunlight exposure, and thermal conditions, landscape architects can design areas that not only provide comfort but also diversify microclimates. This approach enhances the overall user experience, ensuring that outdoor spaces are attuned to the nuances of their immediate environment.

5. Water Management

Parametric landscape design is instrumental in the efficient water distribution and drainage in landscaped areas. Architects can model and analyse water flow by incorporating features like permeable surfaces, rain gardens, and dynamic water elements. Additionally, smart irrigation systems can be deployed to respond to real-time data. This facilitates the optimisation of water management strategies, ensuring sustainable water conservation practices.

Parametric Landscape Design in Action

Situated at the Serpentine Gallery in Hyde Park, London, the Serpentine Pavilion serves as an annual architectural showcase, featuring the distinctive work of various architects. In 2016, Bjarke Ingels Group (BIG) took the helm, presenting a striking example of parametric landscape design. The pavilion’s design was a complex sculptural form that adhered to simple geometric rules, leveraging web technologies for its modelling.

Characterised by the pattern of an "unzipped wall," the structure’s design ingeniously splits a straight line of tubular fibreglass bricks into two undulating sides. This recurring brick geometry echoed the playful aesthetics found in Lego and Minecraft, while the overall structure exhibited the meticulous precision of an algorithm.

In Conclusion

As technology continues to advance and design boundaries are pushed, the integration of parametric principles will undoubtedly play a crucial role in shaping the future of landscape architecture. The symbiosis between cutting-edge technology and parametric design not only enhances the efficiency of the architectural process but also paves the way for innovative solutions to complex challenges.
