About

OctoMass is a Grasshopper plugin developed at Iran University of Science and Technology to assist in the early stages of sustainable architectural design. It integrates computational geometry, environmental data analysis, and parametric modeling to support designers in shaping energy-efficient building forms.

The plugin offers a range of components that allow users to generate building masses based on contextual parameters, evaluate envelope properties, analyze climatic data, and detect overheating risks. These tools are tailored to help architects make informed design decisions with minimal effort during conceptual phases.

Developed collaboratively by faculty, graduate students, and sustainability experts, OctoMass embodies a research-driven, educational approach to design technology—empowering users to bridge the gap between form-making and performance simulation.

Goals

OctoMass was initially developed as a research and educational tool to introduce generative models into sustainable architectural design workflows. Rooted in academic exploration, its early focus was on helping students and researchers grasp the fundamentals of computational design thinking—particularly form-finding strategies shaped by environmental factors. The plugin aimed to bridge the gap between theory and practice by offering tangible tools for generating, analyzing, and evaluating building forms in early design stages.

Through studio-based experimentation, students learned how design parameters such as area, height, solar exposure, and thermal zoning could influence the evolution of architectural massing. This hands-on approach fostered a deeper understanding of sustainability principles and empowered a new generation of architects to think algorithmically about form and performance.

Now, the project is evolving beyond academia. In collaboration with the School of Architecture at Iran University of Science and Technology and NexoNest, OctoMass is transitioning into a fully deployable design tool for real-world application. With its components being fine-tuned and expanded—such as aperture control, shading systems, and overheating detection—it is positioned to support professionals in computational sustainability, early-stage design decision-making, and climate-responsive architecture.

OctoMass continues to grow through interdisciplinary collaboration, empowering both emerging and practicing designers to integrate environmental logic into the creative process—whether in the classroom, the studio, or the market.
