C.Scale User's Guide

C.Scale is a whole life carbon tool delivering carbon clarity from concept to construction. It starts with simple inputs at the earliest project stages, then increases modeling resolution as your design progresses—from early massing studies to detailed assembly modeling and product selection—while keeping the context for your carbon decisions throughout the project lifecycle. Its model combines regionally-specific background data, forward-looking projections, peer-reviewed findings, and industry-leading ML models to assess the relative impact of carbon reduction measures on a project’s embodied, operational, and landscape carbon footprints.

The most impactful carbon decisions happen at the beginning of a project, before granular data is available. C.Scale connects those early decisions through to construction, maintaining context as modeling resolution increases.

Time-based climate targets cannot wait for late-stage data, so C.Scale is the first step in an iterative low-carbon design process: it sets strategies and project-level targets that you refine throughout the project lifecycle.

How project teams use C.Scale

• Set a whole life carbon budget for a project.
• Identify carbon hot spots early and evaluate the most impactful reduction strategies, when the potential for change is highest.
• Increase modeling resolution as design progresses, from massing-level estimates through detailed structural, enclosure, and interior modeling.
• Select specific products from the EPD library to support committed design decisions.
• Compare whole life carbon emissions across projects in your portfolio.

C.Scale works like a shoebox model at the start of a project—simple inputs, fast iteration, and a clear picture of where emissions come from—and fills in as the design progresses, all in one continuous workflow.
