Building program and area reconciliation
Reconcile gross, assignable and residual support areas before using a program total in other decisions.
How to use this idea
The checker uses a deliberately simple convention: each row is one floor, assignable area equals gross area multiplied by an authored ratio, and residual support equals the difference. It does not add circulation a second time. All rows share one unit. Zoning and rentable area remain undefined because their measurement rules are not supplied.
Worked illustration
Two synthetic floors of 1,000 m² at 70% assignable yield 2,000 m² gross, 1,400 m² assignable and 600 m² residual support. Raising one ratio to 80% changes assignable area by 100 m² but leaves gross area unchanged.
All numerical examples here are synthetic, not measured building results.
Checks before relying on a result
- Use unique floor IDs and one area unit.
- Keep voids and external terraces outside this enclosed-area example.
- Do not label the residual as a verified room-by-room support schedule.

What this does not establish
Ratios are assumptions; arithmetic consistency is not evidence of sufficient space, occupancy compliance or a professional measurement standard.
