Smoke Management Calculations
Four independent smoke-control calculators. The worked problems printed in the standard's own annex are carried as permanent test fixtures and still reproduce exactly — the tool is checked against the code book, every release. The engineer picks the design basis; bases are offered side by side rather than assumed.

- Stairwell pressurization — leakage inventory, orifice flow, stack effect and the door-opening force check, against five selectable design bases.
- Lift / hoistway pressurization — the same physics for the shaft.
- Corridor smoke extract — extract rate with the make-up air balance.
- Atrium smoke management — design fire, plume, smoke-layer temperature, plugholing, make-up air and opposed airflow.
