1.Functional requirements, as a basis for inspection

- Expected/required function

- Observations (ocular and by measurement)

- Criteria for acceptance

2. Practical methods to document of proper function

- Measurement methods, instruments and devices

(pressure differential, air velocity and air flow rate)

- Accessibility

- System in the correct state of operation

3. Modern challenges

- Demand Controlled Ventilation: Handover tests and functional testing

- Understanding the principle of control of VAV systems
