Bbs Climawin -

is a French engineering software developed by BBS Logiciels used for calculating the thermal, energy, and environmental performance of buildings. It is widely used by design offices and architects to comply with French regulations like RE2020 , RT2012 , and DPE 2021 . Official Guides and Documentation

One of the most significant advantages of the BBS ecosystem is the integration of Building Information Modeling (BIM) through the module. While ClimaWin is a standalone desktop application, ClimaBIM acts as a plugin that operates directly inside Revit or ARCHICAD interfaces.

, this suite has become a cornerstone for professionals navigating the complex requirements of thermal and energy performance. The Blueprint of Efficiency bbs climawin

Detailed heating and cooling load calculations (NF EN 12831 and ASHRAE) and thermal bridge analysis using finite element methods.

This article provides an in-depth look at BBS ClimaWin, its core functionalities, its role in regulatory compliance, and how it empowers construction professionals to design sustainable buildings. What is BBS ClimaWin? is a French engineering software developed by BBS

: Measures thermal energy lost through walls, windows, roofs, and integrated insulation layers according to the NF EN 12831 standard.

The software is structured into modular packs designed for specific engineering tasks: While ClimaWin is a standalone desktop application, ClimaBIM

At its heart, ClimaWin calculates (déperditions) according to the NF EN 12831 standard and heat gains (apports) using the ASHRAE method . These calculations are essential for sizing heating and cooling systems correctly.

: Calculate precise heating and cooling needs using advanced modules for thermal bridges and climate adaptation. Regulatory Compliance
