Hi Ross, Anthony, Cattaca, and Monty,
Thanks for your interest in Nexii! We’re delighted to be a recent sponsor of CLF and work with / learn from this community. Our proprietary material Nexiite is a high-strength modified polymer concrete, which itself has ~ 30% reduced carbon emissions during production compared to Portland Cement concrete. We use Nexiite cast in beds to encapsulate an EPS core which serves as the panels’ insulation, and add structural reinforcement as needed depending on building typology and design.
We work with third-party LCA consultants to assess the embodied carbon of our product. Our initial estimates of 20% savings are based on our commercial retail unit (CRU) panels and look at the whole building including structure and foundation. When we assess Nexii envelope panels alone, embodied carbon savings range from 33% over baseline (industrial) to 63% over baseline (ornamental). The baselines we use for our studies are as-built drawings from equivalent conventionally designed buildings or building components, where available provided by the client.
As a company in scale-up phase, our fabrication plants are not yet running at 100% optimized capacity; as such the embodied carbon performance of panels can range significantly depending on the month produced. We are committed to pursuing an Environmental Product Declaration for our panels once our Squamish plant has been in full tilt operation for a minimum of 12 months, in accordance with standards, and look forward to sharing this with the CLF community when available. Feel free to reach out with any other questions!
