BBS Climawin is not just a “U-value calculator” – it is a decision tool for durable, healthy, and energy-efficient building envelopes. It bridges the gap between simplified normative checks and full research-grade simulation. For any architect or building physicist working on high-performance assemblies in Central European climates, mastering Climawin is a practical necessity to avoid condensation, mold, and premature building failure. Its German engineering DNA ensures rigor, but its usability makes it accessible – a rare balance in building physics software.

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

BBS ClimaWin is a clinical classification and scoring system used to describe patterns of infant and pediatric bronchiolitis severity and progression. It combines clinical signs (breathing effort, oxygenation, feeding tolerance, and general appearance) into a structured score to aid clinicians in assessing disease severity, standardizing documentation, guiding treatment decisions, and tracking response to therapy. The system emphasizes reproducible bedside measurements and is often used in emergency departments, pediatric wards, and research settings evaluating bronchiolitis interventions.
To the uninitiated, the Climawin looks like a standard three-piece wheel with a lot of spokes. But look closer, and you’ll see the genius of the design.
Most wheels "pump" air. As the wheel rotates, the spokes act like a crude fan, moving air around the wheel well. The BBS Climawin turned this concept inside out. The name itself is a portmanteau of "Climate" and "Win," and it was essentially a turbine for your brakes.
The wheel featured specially shaped fan spokes (often 15 or 18 of them) that were aerodynamically optimized to function as a centrifugal fan. Unlike a standard mesh wheel that just lets air pass through, the Climawin actively sucked cool air from the center of the wheel and forced it outward, over the brake rotor and caliper.
Simultaneously, it created a vacuum effect that pulled hot air away from the brake assembly. It was active cooling without the need for external ducts or electric fans.
While exact item names and scoring ranges can vary by version, BBS ClimaWin generally includes the following domains:
Scoring: each domain is assigned numeric points; total score correlates to mild, moderate, or severe bronchiolitis. Cutoffs and weighting differ among published adaptations.
