š Methodology
How we compute, what we assume, and where the data comes from. Everything is auditable.
Core Formulas
| Formula | Description | Unit |
|---|---|---|
| UA = Ī£(Uā Ć Aā) | Building heat loss coefficient | W/K |
| Q = UA Ć HDD Ć 24 / 1000 | Annual heating demand | kWh/yr |
| E = Q / COP | Electrical energy for heating | kWh/yr |
| Cost = E Ć Price Ć (1+VAT) | Annual heating cost | EUR/yr |

Trinity Rules
| Rule | Description |
|---|---|
| TR1 | No source, no number |
| TR2 | All ingests produce manifest + SHA256 + root_hash |
| TR3 | Every chart links to evidence record IDs |
| TR4 | Model changes bump methodology version |
| TR5 | Only human approves merge to main |
| TR6 | Claude generates code ā NEVER data values |
| TR7 | Witness mode = NO interpretation |
| TR8 | Every claim must be a clickable evidence link |
| TR9 | Proof Pack = raw + canonical + manifest + hashes |
