Lesosai is a software for the certification and thermal balance calculation of buildings containing one or more heated or cooled zones. Simple and effective, the monitors adapt the required information to the needs of the chosen standard or label. It is designed primarily for building engineers, HVAC engineers and architects.
The software can be used in the following languages: French, German, Italian and English. It can use many calculation methods, which can be selected one after another.
Lesosai allows the calculation of environmental impacts of the energy consumption, considering the energy used in the building, but also the building’s construction materials (Life Cycle Impacts Analysis / Environmental Assessment). This calculation is based on a building life cycle approach and uses the list of impacts maintained by KBOB (extracted from the Eco Invent database), and the methodology conforming to Swiss Standard SIA2032 (Life Cycle Impacts Analysis complete with ECO+® module).
Compatible BEM (Building Energy Modelling) via the gbxml format.
gModeller by GSL enables the export and import of gbxml models.
gModeller v2.2.4 now has greatly improved performance particularly on MacOS.
