What’s inside
- Regulatory framework as of October 2026: DBN V.2.3-15 (amendments Nos. 1–3), DBN V.2.5-56 (amendments Nos. 1–2), DSTU EN 12101-3:2017, DSTU CEN/TS 12101-11:2026 — with the clause numbers that the design expert review checks most often.
- Everyday ventilation: calculation for CO dilution, separate systems for each underground level, CO monitors with automatic ventilation start.
- Smoke extraction: the start-up sequence of the systems, automatic, remote and manual start, category I power supply, a limit of 900 m² per smoke intake device.
- Fans: EN 12101-3 classes (F300 — 60 min, F400 — 120 min), high-temperature safety switches, bypass of protections in fire mode.
- Justification of the jet fan system: when CFD modelling is required, which scenarios and criteria to set, what the report must contain.
- Input data for the calculation: the list of drawings and parameters to prepare before contacting an engineer.
Who will find it useful
- designers of HVAC and fire protection systems;
- technical clients and developers who check a contractor’s solution;
- installation companies preparing for commissioning.
The checklist is reference material and does not replace the design calculation. Check the clauses of the norms against the current editions on the e-construction.gov.ua portal.
