The answer is expensive, technically demanding, and visually stunning. For the standard residential home, it is overkill. For the heritage passive-house project, it is currently the best tool on the market.
: Using advanced nodal analysis methods (such as ISO 13790 ), ClimaWin simulates hour-by-hour building behavior. This allows designers to predict real-world indoor temperatures, energy usage peaks, and natural shading interactions across varying yearly weather cycles.
: The software is used to perform mandatory calculations for the current French environmental regulation (RE2020) and the previous thermal regulation (RT2012), including the generation of mandatory PC deposit certificates.
: Through the ClimaBIM plugin for Revit , users can perform thermal and regulatory calculations in real-time directly within their BIM environment, eliminating the need for tedious data re-entry.
ClimaWin integrates the latest 3CL-DPE method, allowing users to generate mandatory energy labels for existing buildings. bbs climawin

is a French-developed software suite specialized in the thermal and environmental performance of buildings. Primarily used by thermal design offices and architects, it serves as a critical tool for ensuring regulatory compliance and optimizing energy efficiency in both new constructions and renovations. Core Functionalities
Based on European standards (like EN 12831), preventing the oversizing or undersizing of heat pumps, boilers, and chillers. The answer is expensive, technically demanding, and visually
In modern architecture and civil engineering, software tools determine project viability, regulatory compliance, and environmental footprint. Among the specialized tools available in the European market, BBS ClimaWin stands out as a premier software suite for thermal, acoustic, and environmental simulation. Developed by BBS Slama, this comprehensive software package is designed to help engineers, architects, and thermal design offices meet stringent building regulations while optimizing structural energy efficiency.
Handles the latest French and European standards, including the RE2020 and RT2012 regulations. 3D Scene Visualization: Recent updates include a 3D scene viewer
In the world of building design and energy efficiency, precision is essential. Whether you are an architect designing a new housing project, a consulting firm conducting an energy audit, or a contractor aiming for regulatory compliance, having the right software can make all the difference. "BBS Climawin," often referred to as ClimaWin, is a leading solution in this field. Developed by the French company BBS Slama, this software has established itself as a benchmark for thermal, energy, and environmental calculations in the construction industry.
: Manages compliance calculations for building extensions or comprehensive energy overhauls of existing structures. Thermal Load & Sizing Calculations : Using advanced nodal analysis methods (such as
The software is continually updated to align with active European and French energy codes.
The software is structured into modular packs designed for specific engineering tasks:
