Ciaran Garrick

Associate Director, Head of Design Technology

At Allies and Morrison, we approach every project with a deep appreciation for the intrinsic connection between architecture, urbanism, and sustainability. From the outset, Orbital Stack's advanced climate analysis tools have complemented our rigorous design process, allowing us to explore concepts that are responsive to the local context, and grounded in sustainable principles. One of the hallmarks of our collaboration with Orbital Stack is the emphasis on flexibility and adaptability. The analysis integrates well with our existing technology ecosystem and allows us to explore design options efficiently within the surrounding environment. As we continue our journey with Orbital Stack, we are excited at the prospect of driving new and innovative forms of sustainability analysis in our design process.

Arq. Armando Montes de Oca

PM, The Façade Studio

The experience of using the Orbital Stack platform for wind simulation completely redefines how we approach architectural design and urban planning. Orbital Stack not only simplifies the wind flow simulation process but also offers an intuitive interface that facilitates the interpretation of results. The platform allows us to dynamically visualize how the wind interacts with facades and structures, providing detailed insights crucial for informed decision-making.

Architect, Partner

Efficient, seamless. this tool has an opportunity to be a dominant yet unassuming tool for all architects and urban designers out there. it would be preferable to have a per project pricing offer.

Afaq S.

Senior Associate

Using advanced AI models trained on extensive wind data collected by RWDI, this software helps our us enhance the pedestrian comfort design of our urban environments. The software accounts for factors such as wind speed, direction, and surrounding structures. it has an intuitive user interface which is visually appealing, easy to navigate and makes it accessible to all our staff. Users can quickly upload project-specific data and get analyze results in ~30 minutes. This helps run multiple iterations due to the quick feedback.

Hiram R.

Design Technologist

Really great team and expertise for a hard problem to solve. the fact that you can also reach out to other experts on wind analysis within RWDI that makes it even better.

An Orbital Stack User

Architectural Designer

The user interface and visualizations of the results are pretty neat. The technical support team is quite responsive, and I find that my queries have always been resolved at the earliest. The overall experience using the tool so far has been wonderful, and I highly recommend Orbital Stack to the firms in AEC industry.
