Free calculation. No sign-in. No selector journey.
This public calculator does not recommend a manufacturer, catalogue item or equipment model. It sends declared inputs to the protected Adelphos calculation service and never falls back to browser arithmetic.
No account or Adelphos project is required. No HTML report is offered. The downloadable report is the Adelphos-branded PDF returned by the protected report service.
How does the Ventilation Calculator work?
Enter the room use, floor area or volume, occupancy and the applicable design criterion, such as airflow per person, airflow per area or air changes per hour.
What the Ventilation Calculator calculates
The Ventilation Calculator uses declared design information to calculate the required ventilation airflow. Enter the real project inputs, review the result and download an Adelphos-branded PDF report.
Design information you need
Enter the room use, floor area or volume, occupancy and the applicable design criterion, such as airflow per person, airflow per area or air changes per hour.
Calculation result and PDF report
The result returns the required supply or extract airflow and the controlling criterion for review within the complete ventilation strategy. A successful calculation can also produce an Adelphos-branded PDF report.
Checks, limits and responsibility
This calculation is an aid, not a design approval. The user must verify every input, applicable standard, result and its suitability for the project.
How to use the Ventilation Calculator.
The calculation follows four clear stages: gather verified information, enter the design inputs, calculate, then review the returned checks and report.
1. Gather the source information
Enter the room use, floor area or volume, occupancy and the applicable design criterion, such as airflow per person, airflow per area or air changes per hour.
2. Enter the design inputs
Use consistent units and declare every required assumption. This calculator does not silently replace missing required values with convenient engineering defaults.
3. Run the protected calculation
Submit the form to the Adelphos calculation service. The calculation performs no fallback arithmetic in the browser and returns only the public result needed for review.
4. Check the result before use
The result returns the required supply or extract airflow and the controlling criterion for review within the complete ventilation strategy. Check the result against the coordinated design, current project requirements and competent-person review.
Ventilation Calculator searches covered by this page
This page answers the practical search intent behind the Ventilation Calculator: which inputs are needed, what the calculation returns and what must still be checked by the user.
The user is responsible for verifying all inputs, assumptions, standards, selections, outputs and suitability, and for obtaining competent-person review. Adelphos accepts no responsibility for decisions made using this calculation.
