This document discusses the user requirement specifications (URS), design qualification (DQ), installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) of heating, ventilation, and air conditioning (HVAC) systems used in pharmaceutical plants. The HVAC system must be qualified to ensure it is designed and installed properly and works as expected. The URS define the room temperature, humidity, and air cleanliness requirements. The DQ confirms the design meets the URS. The IQ verifies correct installation. The OQ tests the system operation. Finally, the PQ assesses the HVAC performance under normal operating conditions.

- 2. Introduction Heating, Ventilation and air – conditioning (HVAC) systems are used in pharmaceutical plat to prevent contamination and to provide comfortable working conditions. HVAC are called Air Handling Units (AHU). AHU comprises of air supply, coarse filtration, heating or cooling and HEPA filtration. Flow of air into the room may be horizontal or vertical. AHU producing class A (class 100 L), class B (class 100 T) & class C (class 10,000) HEPA filters may be located in AHU.
