The Passive House Institute (Darmstadt, Germany) certifies components suited to passive construction. The building system presented here has been certified in the “building system, solid construction” category, for the cool temperate climate.
Criteria assessed
| Criterion | Requirement |
|---|---|
| Hygiene: minimum temperature factor of interior surfaces | ≥ 0.70 |
| Comfort: U-value of installed windows | ≤ 0.85 W/m².K |
| Efficiency: heat transfer coefficient of the envelope | ≤ 0.15 W/m².K |
| Efficiency: temperature factor of opaque junctions | ≥ 0.86 |
| Efficiency: thermal bridges of the main connections | Ψ ≤ 0.01 W/m.K |
U-values determined for the system
| Element | Thickness | U (W/m².K) |
|---|---|---|
| External wall | 0.48 m | 0.136 |
| Roof (variant 1) | 0.44 m | 0.096 |
| Roof (variant 2) | 0.37 m | 0.111 |
| Flat roof | 0.43 m | 0.136 |
| Basement ceiling | 0.46 m | 0.144 |
| Slab on ground | 0.41 m | 0.210 |
| Basement wall | 0.49 m | 0.136 |
A component certification does not, on its own, guarantee that a building reaches passive level: this depends on the overall design, the workmanship and the study of your project.
