Climawin used hardware dongles (parallel port keys) for DRM. Without the dongle, the software was useless. When hard drives failed or dongles were lost, official replacements were impossible to find. BBS Climawin threads from the late 90s contain the original discussions on how to bypass these locks or emulate them using modern virtual serial ports.
Today, the BBS Climawin sits in a strange spot in the automotive hierarchy. It is overshadowed by its more famous sibling, the BBS RS, which became the darling of the stance and VIP communities.
However, the Climawin is currently enjoying a renaissance. As 90s "Youngtimer" cars surge in popularity, enthusiasts are rediscovering these wheels not just for their looks, but for their mechanical intrigue. They represent a time when manufacturers would engineer a complex, three-piece turbine wheel just to solve a cooling problem, rather than simply printing a plastic cover to simulate the look.
If you see a set of Climawins on a car today, you aren't just looking at a set of rims. You are looking at a wind tunnel experiment that escaped the lab and hit the road.
The blueprint for the high-rise sat on Julian’s screen like a digital maze, a complex web of heat loss and energy gains
. Outside his window, a Paris summer was already beginning to bake the pavement, but inside his workspace, everything was governed by the cold, precise logic of BBS ClimaWin
Julian was a thermal engineer, a man who spoke in U-values and thermal bridges. For weeks, he had been wrestling with the "Green Spire," a project that promised to be the first net-zero residential tower in the city. The deadline for the RE2020 regulatory submission was looming, and the numbers weren't clicking. He opened the software, the familiar interface of ClimaWin 2020
greeting him with its restructured menus. He clicked through the graphic editor, tracing the edges of the building's envelope.
"Come on," he muttered, adjusting the thickness of the insulation on the northern facade. "Give me the gain I need."
He ran the calculation. The engine whirred—a sophisticated piece of code provided by the
—simulating thousands of hours of sunlight and wind. The progress bar crawled across the screen. When it finished, the results were highlighted in a stubborn, glaring red. The building was still bleeding heat through the balconies. Julian sighed and rubbed his eyes. He thought about the
training sessions he’d attended, the instructors emphasizing the importance of thermal bridges in the new regulations. He went back into the catalog, searching for a specific type of thermal break he’d seen in a recent BBS newsletter
He swapped the components, linked the new environmental data to the envelope, and hit 'Calculate' one more time. ClimaWin 2005 - le logiciel intégré RT 2012

One of the most powerful features of the suite is ClimaBIM. This plugin allows users to perform thermal and regulatory calculations directly within the Autodesk Revit interface. It bridges the gap between architectural design and energy analysis by: Bbs Climawin
In the world of French architecture and engineering, BBS ClimaWin
isn't just software—it’s the "silent partner" behind thousands of energy-efficient buildings. Developed by , a company founded in
in Clermont-Ferrand, the story of ClimaWin is one of staying ahead of a rapidly changing climate and even faster-moving government regulations. The Evolution: From Blueprints to BIM
For over 40 years, BBS Slama has evolved from a small engineering firm into a software giant used by over 3,000 design offices
. The "ClimaWin" story followed the path of French energy laws: The Early Days:
Engineers used it to calculate simple heat loss and size radiators. The RT2012 Shift:
As France moved toward tighter thermal regulations (RT2012), ClimaWin became the essential tool for certifying that new homes wouldn't leak energy like a sieve. The 2020 Rebirth: In 2021, the company launched ClimaWin 2020
, a complete "ground-up" rebuild designed to meet the strict new
environmental standards. It wasn't just about heat anymore; it was about the carbon footprint of the materials themselves. The Software "Hero"
In this story, ClimaWin acts as a bridge. It allows a designer to build a "thermal twin" of a building. Through modules like , it plugs directly into Autodesk Revit
, allowing architects to see the energy impact of a window or a wall in real-time as they draw. Current Chapter: The Race for 2026
The latest updates in early 2026 show the software tackling the "Tertiary Decree,"
expanding its reach to museums, courts, and theaters to ensure even large public spaces meet carbon-neutral goals. Despite its technical nature, the humans behind it—like founder Bruno Slama
—often use their platform to advocate for more scientific rigor in energy audits, famously warning against "disasters" in diagnostic methods that aren't properly validated. Bbs Climawin
