Industry experts praised it for breaking the trade-off between design flexibility and energy efficiency, while real estate representatives noted its role in boosting green certification and living quality. Rolf Demmler, DGNB China Ambassador, confirmed the system meets DGNB standards in supply chain transparency and EPD compliance.Founded in 1835, Sto is listed on the Frankfurt Stock Exchange (since 1992) with 32 global factories and 50+ subsidiaries.
