Envilop is a lightweight wood-based suspended façade system developed by the CTU UCEEB as an alternative to traditional metal façades to increase energy efficiency in both new buildings and renovations. This innovative system has been licensed to several companies, which has facilitated its wider use in the field of sustainable architecture. A significant implementation of Envilop took place during the comprehensive renovation of the Českobrodská Secondary School in Prague, which transformed a 1970s building into a modern, energy-positive educational facility. The project used the Envilop façade system, licensed to SUBTERRA and manufactured by NEMA in cooperation with WOODRISE. This refurbishment not only elevated the building to an energy plus standard, but also won several national and international awards. For UCEEB, the Envilop project means economic benefits through royalties and, most importantly, a long-term reduction in the building's energy consumption and carbon footprint. The project is an example of a successful research-industry collaboration that promotes sustainable building practices.
