Intry Verified receipt
Is the Intry BTU / HVAC Load Calculator accurate?
The provenance receipt for the Intry BTU / HVAC Load Calculator: the exact authority its numbers derive from, the edition they are keyed to, who has final say, and how a deploy gate holds every figure to its cited source.
Short answer: Every calculated figure is re-derived from its locked source before any deploy, backed by 4889 automated checks that also guard where each number comes from. A number that drifts from the ACCA Manual J basis it came from blocks the ship. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- the ACCA Manual J basis it came from. Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any deploy, a deterministic test suite re-derives every calculated figure from its locked source and checks it against the actual published source it cites, so the number is right, not just consistent with itself. As of the current build that suite holds 4889 checks, and it gates this page too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine that powers the published numbers. It is not exposed as a runnable MCP tool.
- Final say
- A full Manual J on the actual house has final say.
