ABOUT SOFT ÉTUDES
Practical engineering tools, clear assumptions
Soft Études is an independent collection of practical calculators and technical guides for engineers, technicians, installers, craftspeople and students.
What the platform provides
The calculators turn common engineering inputs into readable preliminary results. Each tool shows its assumptions, key outputs and limitations so that the result can be checked before use.
How results should be used
Soft Études supports preliminary sizing and technical discussion. It does not replace a complete design, an approved construction calculation, applicable standards or manufacturer selection software.
Independent development
The platform grows from practical technical needs and user feedback. Corrections and useful additions are introduced progressively, while the calculation engines remain shared between the French and English interfaces.
The English pages are translated and reviewed in planned groups. A calculator is added to the English catalogue only when its inputs, outputs and technical warnings can be presented clearly. French tools that depend on local tariffs, regulations or specific national practices remain outside the English catalogue until an appropriate adaptation is available.
Transparency and feedback
Default values are examples, not project recommendations. Sources and calculation limits are kept visible wherever they help explain the method. Users can report an unclear label, a suspected result or a missing case so that the relevant module can be reviewed.
The platform is intended for repeated practical checks as well as learning. A result should remain understandable after it has been exported or revisited later, which is why input assumptions, units and limitations are treated as part of the calculation rather than secondary information. English terminology follows common international HVAC and building-services usage where possible.
