Lesosai is a powerful and comprehensive computer program designed to calculate and optimize the energy balance and life cycle assessment of buildings with heated or cooled zones. It is widely used for building certifications and integrates seamlessly with BIM (Building Information Modelling) and BEM (Building Energy Modelling) processes, making it a trusted tool for architects, engineers, and energy consultants.
The software supports multiple calculation methods tailored to Swiss and European standards and offers a user-friendly interface that adapts dynamically to the requirements of the selected certification label, norm, or standard. Available in German, French, Italian, and English, Lesosai ensures accessibility across diverse user groups.
Key features of Lesosai include tools for optimizing heating, cooling, hot water demands, and electrical requirements. Users can easily enter building data through three methods: traditional plans, guided assistance (ideal for preliminary projects or renovations), or direct BIM/BEM integration via IFC or gbXML formats from tools like Revit, SketchUp, and ArchiCAD.
Lesosai offers seamless compatibility with other programs, including GEAK, flixo, EN101b, epiqr+, and BCF, and supports customized reporting for enhanced usability. Developed by experts involved in drafting Swiss and European energy standards, it has been refined since 1984 and benefits from direct collaboration with decision-makers.
