HVAC Controls QA
Zero-integration QA for AHU controls. Upload SOO, points, and historical trend exports, then produce an evidence-backed report without a gateway, BAS connection, or control writes.

REALITY CHECK · FAIL
Why this is different
AI reads the spec. The evaluator decides the result.
CrewMultiplier can use an LLM to extract candidate requirements and suggest point mappings, but PASS/FAIL is produced by deterministic rules over approved mappings and timestamped trend evidence.
What variables actually exist, separated by equipment and point semantics.
What happened over historical observations, with missing data preserved.
Every status links back to source, mapping, rule, and evidence window.

AHU-9 deviated outside approved tolerance after the grace period.
AHU-10 cooling and heating commands were both active for a sustained window.
The public sample lacks enough independent feedback to prove the claim.
Commercial MVP workflow
Files → review → deterministic analysis → evidence → PDF.
- Text-based SOO PDFs become reviewable AHU requirements.
- CSV trend imports support wide and long BAS export formats.
- Ambiguous phrases such as “outdoor conditions are favorable” are flagged for review instead of guessed.
- Private guided demo uses public benchmark trends and clearly labeled demo-authored supplements.

Public-data posture
Demo without exposing customer buildings.
We separate real public benchmark data, simulated public benchmarks, method references, and demo-authored supplements so the report does not overstate the source.
Benchmark precision, recall, and false-positive claims should only be published after measured runs against the public validation suite.
CSIRO AHU Fault Detection Dataset
Real public BMS data from AHU9 and AHU10 in an operational office building, with public fault experiment metadata.
Open sourceLBNL Fault Detection and Diagnostics datasets
Published HVAC fault datasets include labeled time-series data, point documentation, and system/control context for benchmark testing.
Open sourceErie County AHU sequence drawings
Public bid drawings include AHU sequence language for economizer, fan control, chilled-water cooling, reheating, humidity, and reset logic.
Open sourceDepartment of Veterans Affairs controls drawings
Public procurement documents include mixed-air AHU sequence sheets and points-list/sequence references that can exercise extraction review.
