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

  1. Pick a tool from a category (ventilation, hydronics, etc.).
  2. Enter the data you have (flows, diameters, temperatures…).
  3. 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.
