For engineering firms ยท ASHRAE Levels 1, 2, and 3
Audit drafts in hours, not weeks.
BuildingAudit turns utility bills and building data into a PE-ready ASHRAE audit draft, with every number traced to its source or flagged for review. Level 1 is open to early access now; Levels 2 and 3 run on the same engine next. Your engineer reviews, finishes, and signs.

How it works
A Level 1 audit is mostly disciplined assembly: bills, benchmarks, walk-through notes, measure screening, report. The engine does the assembly. The engineering stays with the engineer. Deeper levels add data and depth, not a different discipline, which is why Levels 2 and 3 ride the same engine.
1
Send the documents
Utility bills, building basics, and walk-through notes. Extraction runs against the original documents, so nothing is keyed in twice.
2
The engine drafts
Bill data is extracted with page-level evidence, benchmarked, and run through deterministic calculations built on public technical reference manuals. A gate blocks any number that lacks a source.
3
Your PE finishes and signs
The draft arrives with the evidence behind every figure, so review starts from the sources, not from reconstruction. Your professional finishes it, stamps it, and owns it.
Built for the compliance calendar
Benchmarking and building-performance ordinances put firms on deadline-driven audit and assessment calendars, with penalties behind the dates. BuildingAudit is the fast lane for the drafting half of that work, and NYC's LL87 deliverable is a Level 2 audit, which is exactly where the engine goes next.
Why it is different
Every number has a source
Each figure in the draft links back to the bill line, document page, or reference table it came from, or arrives explicitly flagged. Reviewers see the evidence, not just the answer.
Deterministic calculations
Savings math runs on public technical reference manuals, not a black box. The same inputs produce the same outputs, every time.
An anti-fabrication gate
A number without a source does not ship. The gate holds the draft until every claim is traced or explicitly flagged for the reviewer.
A tool for professionals, not a replacement
BuildingAudit produces drafts for review and certification by your licensed engineer. It is not an engineering service, and it never signs an audit.
