HVAC sizing tools for Switzerland
hvac-tools.ch provides practical HVAC calculators (heating, ventilation, air-conditioning) aligned with Swiss engineering habits and design-office workflows.
Goal: quick calculations, readable assumptions, and outputs you can reuse from early design to execution.
Why this platform?
Save time without sacrificing reliability: fewer scattered Excel files, more consistency across projects, and fast checks when decisions must be made quickly.
Covered domains
Ventilation
Pressure-loss checks, duct sizing, and quick validations for efficient air distribution.
Hydronics
Pressure drop, pipe sizing, and quick checks for heating/cooling water loops.
Psychrometrics
Moist-air analysis for air-treatment processes and thermal comfort studies.
Sanitary
Support for cold water/DHW sizing and baseline network checks.
How to use
- Pick a tool from a category (ventilation, hydronics, etc.).
- Enter the data you have (flows, diameters, temperatures…).
- Use the results for quick checks, a short calc note, or a sizing baseline.
Who is it for?
- HVAC engineers and designers.
- MEP design offices standardizing preliminary checks.
- BIM coordinators / technical project managers.
- Commissioning: on-site checks and verifications.
Quality & limitations
These tools support quick sizing and validation. They do not replace detailed engineering: always verify assumptions, units, and applicable project requirements/standards.
Quick access
FAQ
Are the tools adapted to Swiss regulations?
They follow common Swiss practices and units. Final validation is always required for your specific project and applicable standards (SIA/EN, etc.).
Can I export results?
Depending on the tool, you can print or export a summary. Export features are improved progressively.
Is it free to use?
The platform is currently free for professional use, with continuous module improvements.
