- It offers room and per-level totals, CSV export, and an A4 report; the page says scanned sheets may need its optional OCR box.
Field notes
The workflow accepts text-layer PDFs and room schedules in CSV, TSV, or Excel formats, then lets users correct extracted values and adjust inputs such as orientation, height, occupancy, glazing, and walls. Results include component breakdowns and per-level subtotals, with CSV and printable A4 exports. The page lists prefilled design conditions for cities including Kochi and Dubai and links to worldwide ASHRAE 2021 conditions.
