We provide different products to perform the life cycle impacts analysis of a building:

Eco-Sai is the result of the aggregation of two existing tools: Usai 3.0 (building physics) and Eco-Bat 4.0 (LCA). It includes functionalities from both tools. Regarding building physics, it allows the calculation of U-Values (static and dynamic), thermal capacity and humidity (Glaser method) inside construction elements. You can also perform a detailed LCA of various construction elements or even a whole building, including technical systems and energy consumption, acording to swiss standards (Minergie ECO, SIA2032, SIA2040, SNBS, DGNB-SGNI).

Eco-Bat 4.0 is an independant tool with which you can very quicky modelize a building and perform a thorough life cycle impacts assessment. Compared to the ECO and ECO+ modules, Eco-Bat offers numerous additional features and targets users who want a performant user-friently tool that provides them with the most detailed results available. Eco-Bat has been replaced by Eco-Sai in 2015 and is therefore not available anymore.

The ECO module
allows the user to evaluate the environmental impacts of a building modelized in Lesosai. This free module is included in the latest version of Lesosai. It provides a basic display of the gloabl results of the ecobalance and is generally used during the sizing phase.

The ECO+ module, also coupled with Lesosai, provides more detailed results at elements and materials level. The user can easily identify which elements or materials are predominant and act accordingly to reduce the global impacts of the building.

These tools allow the user to perform an ecobalance conform to the Minergie-ECO® standard and to SIA2032 technical book.
