Calculation result and PDF report
The result is an early heat-demand estimate for option review. It is not a certified PHPP model or Passivhaus assessment. 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 Passivhaus Heat Demand Estimate.
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
Provide treated floor area, fabric heat-loss data, ventilation and heat-recovery assumptions, internal and solar gains, and the applicable climate information.
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 is an early heat-demand estimate for option review. It is not a certified PHPP model or Passivhaus assessment. Check the result against the coordinated design, current project requirements and competent-person review.
