OUR USERS LOVE US
Trusted by architects, engineers, and building product manufacturers.
“We had been looking for the right workflow tool to do reporting on our projects that allows for engagement within our design teams. C.Scale gives us the ability to make informed decisions earlier in the design process.”
Keith Hempel, FAIA
President, Chief Design Officer @ LPA Design Studios
“C.Scale has become an essential part of our design workflow. It enables our teams to evaluate options earlier in the process and helps clients clearly understand how different choices will influence the project’s long-term impacts.”
Jennifer Wehling, AIA, LEED AP BD+C & ID+C, WELL AP
Director of Sustainability @ HMC Architects
“I used graphics from C.Scale to convince a client to do adaptive reuse on an existing building with a Passive House addition versus knocking a whole building down. I'm on board!”
Timothy Lock, AIA
Management Partner @ OPAL
“C.Scale connects us directly with architects specifying on active projects, who appreciate that we have EPDs with verified impact data—and also see our wood light fixtures as part of a larger story, not just a line item.”
Sean Darras
Chief Executive Officer @ Lightly

GET STARTED FREESTART EARLY, FINISH Ahead
Measure your impact early and often.
Without C.Scale
Wait until you have a design to get results
Once you have the data necessary to use other tools, the most important decisions are already made... including architect selection.
Climate impact lives with the specialists
Expertise is needed to master complex tools, conduct bottom-up analysis, and interpret results.
Useful data is fragmented and siloed
LCAs and reports are scattered in PDFs and spreadsheets and siloed across organizations, so data is impossible to access.
Submittals are slow and costly
Keeping up with reporting requirements and formats is best done by dedicated consultants who can keep up with the latest standards.
Low-carbon products are hard to source
Specifiers struggle to identify and verify products with EPDs in a time-efficient manner, while manufacturers search with difficulty for the right projects
With C.Scale
Get results early to win work
C.Scale’s lightweight analysis allows teams to assess carbon emissions up front, helping win work from sophisticated clients.

JOIN THE CROWD
Becoming a core workflow platform for firms across North America.
“We used C.Scale in the proposal stage... I think it set us apart, as we were up against the best firms in the country. What's really amazing is that when we did a detailed LCA, the embodied carbon results were within 5% of the C.Scale estimates!”

FAQ
Frequently asked questions.
A preliminary assessment takes less than 30 minutes, and a more detailed assessment should only take a few hours.
Yes! C.Scale is a free whole life carbon tool for both individuals and firms. You can model unlimited projects in C.Scale to understand the embodied and operational emissions and only pay when you’re ready to do detailed assessments or report for compliance.
Concept-level results represent concept-level designs and are highly uncertain. As more data is entered in the platform, more precise assessments become possible.
We publish our methodology online and are transparent about how we use data from multiple sources to make whole life carbon assessments accessible to everyone. If something’s missing from the methodology or you have other questions, be in touch!
C.Scale is used in coursework at Stanford, Yale, Howard University, UW, and over two dozen other schools across North America. Supporting the next generation of practitioners is an essential part of our mission, and we’re here to help! EDU accounts are always free. Reach out to get set up.
C.Scale loves desk crits! As architects ourselves, walking through specific projects lets us live vicariously through your work. Reach out to schedule 30 minutes with our team for a free consultation on how you can lower the embodied carbon of your project with a minimum of effort.
