For Lesosai 6.0 and 7.0 users who would like to perform a more detailed environmental analysis of their projects, it is recommanded to buy the ECO+ module. This module displays more detailed results. In addition to the features of the ECO module, the ECO+ module provides graphical and numerical results for each elment and each material inside the building.

These comprehensive display features allow the user to quickly identify the predominant components that you have to work on to reduce the global impacts of a Lesosai project  

The ECO+ module uses environmental impacts data from the KBOB LCIA recommandations list, which is based on Ecoinvent.

ECO+ is distributed by the Laboratory of solar energetics and building physics (LESBAT) of the HES-SO of Yverdon-Les-Bains (HEIG-VD).
