Building physics and life cycle assessment calculations
The USai and Eco-bat software tools have been merged to facilitate the work of professionals in the building sector. The result is the first software that makes it possible to analyse the U value, thermal inertia and life cycle assessment of a construction (homogeneous and inhomogeneous). Its intuitive interface and our outstanding customer support will enable you to quickly generate reliable results and realize projects on time along with cost savings.

A tool for facilitating information exchange between building material providers and building physics software, the platform exist since 2007 ( >35 providers and more than 5000 users). E4tech Software SA and the building material providers Flumroc, Isover, Morandi, Pavatex, Swisspor, Tuileries de Fribourg et Lausanne, with the assistance of the Fraunhofer Institute, have developed a new open source format in XML (Extensible Markup Language).
This new tool allows customers to independently manage their own database of construction materials without the need for a central database.
