As designers work to create affordable, high-quality buildings that perform efficiently, they face a growing set of sometimes competing constraints. Sustainability criteria like energy performance, embodied carbon and design for deconstruction often compete with quality criteria like daylight, acoustic performance, solar gain and wind conditions. We use parametric design to guide clients through these dilemmas, helping them to make decisions that work for everyone.
Parametric design is a computer based design approach that treats geometric properties of the design as variables. The dimensions, angles and geometric properties remain malleable as the design progresses. ” Patrick Shumacher Zaha Hadid Architects
A framework for better decisions
Using parametric design, we are able to explore a complete range of design options, building a unified solution that reconciles competing demands. We start by jointly agreeing the boundary conditions and key performance indicators of a project. Using these, we develop a parametric algorithm to generate options that explore the full range of possibilities. We then analyse these options, sharing insights that help our clients make better informed decisions.
For clients like municipal authorities or local government planners, this is a powerful way to balance competing demands such as environmental criteria and plot densities. For investors and developers, these tools and techniques help reveal the business potential of land acquisitions. For architects, they are a valuable means to test and develop innovative designs.
Fuelling more productive conversations
The effort that goes into creating successful schemes is 20% design-based and 80% focused on securing the agreement of all involved. In reality, no single design will meet all the demands of every stakeholder.
Parametric tools not only provide insight in the full range of possible solutions. They also make negotiations more productive, giving everyone involved a better understanding of the key design issues.
We use parametric tools to create a more informed framework for decisions, brokering more productive conversations between stakeholders. The thousands of options parametric models allow us to create and review frees debate from the defence of two or three alternatives. Scoring options clearly against agreed KPIs and highlighting trade-offs gives proposals a transparent logic. One that can be shared and negotiated. In that process, parametric design not helps us navigate to the option with the fewest compromises. Importantly, it also allows us to demonstrate what will not work, and why.
Smakkelaarspark: striking a balance between development and wellbeing
Municipalities redeveloping areas of their towns and cities need to strike a difficult balance. Their ambition for green spaces needs to leave room for opportunities investors and developers will also find attractive. Using parametric design for the regeneration of Utrecht’s Smakkelaarsveld district, we made the quality of a new city park the key design parameter. From this start, we were also able to integrate a residential complex as appealing to investors as the renamed ‘S(makkelaars)park’ will be to Utrecht’s residents.Learn more about or work
Making complexity accessible
Digital technologies are helping us visualise more than the geometries our parametric tools create. By replacing technical documentation with technically robust animations, we build intuitive, accessible visual narratives for a scheme. Narratives that clearly show the interrelationships between different KPIs and the losses and gains inherent in each option. Narratives that can be meaningfully shared with investors, lawyers, and communities, engaging those not from engineering or architectural backgrounds. They help demonstrate the logic for a scheme and provide a shared language to negotiate its final form.
By combining multiple KPIs in a single animation, we can demonstrate their interrelationships and highlight where, why and how trade-offs occur.
Artificial intelligence, human creativity
Our use of artificial intelligence does not replace the designer’s creativity. As sustainability targets place new demands on designers, it is helping them respond imaginatively to these constraints. We use artificial intelligence to drive generative design and use algorithms to optimise that design. It helps us, and our creative partners, explore the full range of design possibilities available within a scheme’s defined parameters.
For the three towers of the Valley in Amsterdam, for example, we used artificial intelligence to automate design verification. Our algorithm for its complex geometries scored each apartment in each design against Dutch daylight and view codes. Using parametric tools to review the building’s highly creative shape also allowed to reduce the different angles, formworks – and overall cost – of the project.
Located close to Schiphol airport and Amsterdam’s city centre, Zuidasdok aims to create a connected urban district for residents, workers and commuters. Improved infrastructure solutions for cyclists, pedestrians and public transport offer a viable alternative to the car.
Our digital tools allowed the team to explore more than 800 options in record time, resulting in the perfect geometrical consistency between perimeter structure and façades with a robust structural design.
To achieve the complex façade of the building, Arup utilised parametric modeling tools that allowed the extensive panels to be rationalised and modulated for accuracy of fabrication.
Theater Zuidplein Acoustic Wall
Bu using parametric 'sound shaping' out engineers ran a series of scenarios to evaluate the impact of the auditorium’s wall design on the acoustics, optimising the final shape of the theatre's striking 'folded triangle' wall - 6,000 unique planels made of aluminium composite.
The new multifunctional complex 'Valley' is a unique and bold architectural design by MVRDV which includes offices, residences, retail and a museum at the ‘Zuidas’ business district. We supported the architectural design with parametrical design services.
Chinese National Stadium (Bird's Nest)
The 'Birds Nest' formed the striking centre piece of Beijing's Olympic Games. Its location in one of the world's most active seismic zones allied to the 'crazed pottery' style required the use of advanced design and analysis tools to deliver this iconic stadium.
Arnhem Central Station
Arnhem's Central Station required us to use 3D modelling to achieve the complex shape of the terminal and successfully integrate the striking glass facade.
The previously unloved downtown area of Smakkelaarsveld, next to Utrecht’s central railway station, will soon be redeveloped into a green area and residential complex, representing an example of digital tools can help deliver unique, sustainable solutions to challenging problems.
