PHI Version 10c contextPartial evidence only

Passive House
Evidence Worksheet

Compare selected PHPP and test values with verified project criteria without assigning Classic, Plus, Premium, EnerPHit, or PHI Low Energy Building certification.

Who it's for: energy consultants and architects checking PHPP and test values at design development against a verified project criterion.

Selected entered criteria
partial comparison; never certification

How to use this calculator

1
Select the exact assessment path
Record the PHI standard/class, version, project type, and alternative path actually being evaluated.
2
Use PHPP and test outputs
Enter only results with the definitions, units, boundaries, and evidence required by that path.
3
Enter verified criteria
The worksheet intentionally does not hard-code a universally applicable set.
4
Keep certification fail-closed
Unless the accredited certifier confirms the complete assessment, the result remains partial and unresolved.

The formula

Each pair uses entered result ≤ entered maximum criterion. Three selected numerical comparisons are reported separately. No class-selection or certification algorithm is executed.

Worked example

Example
Heating demand 14 against 15, airtightness 0.5 against 0.6, and PER 55 against 60 are each numerically not above their entered maxima. The output still says partial evidence only unless complete certification evidence is confirmed.

When this estimate will be off

  • Does not calculate PHPP results, choose a demand/load path, climate criterion, treated floor area, PER boundary, renewable-generation requirement, or certification class.
  • Does not evaluate cooling/dehumidification, comfort, moisture, components, renewables, commissioning, documentation, quality assurance, or scheme-specific exceptions.
  • Airtightness must use the required test method and stage; the worksheet does not validate the test.
  • Only an accredited certification process can establish the final class or award.

Frequently asked questions

A common mistake: Does not calculate PHPP results, choose a demand/load path, climate criterion, treated floor area, PER boundary, renewable-generation requirement, or certification class.

Those outcomes depend on the complete applicable criteria, renewable-generation and energy paths, calculation conditions, evidence, and certification review—not three numbers alone.

The applicable value can depend on the selected standard, version, building category, climate, and alternative path. The responsible team must verify that context.

It records a statement from the certification workflow; it does not turn this worksheet into a certificate or independently verify that statement.
