In the pharmaceutical sector, HVAC systems are critical process assets that safeguard product quality, regulatory compliance, and operational reliability. Designing HVAC systems with strong commissionability and maintainability ensures that facilities can be tested & validated efficiently, operated consistently, and sustained throughout their lifecycle. This philosophy is always at the forefront of BES’s design teams mind and is something we strive for throughout the design process.

Commissionability refers to how effectively an HVAC system can be tested, verified, and qualified to meet stringent regulatory expectations. In pharmaceutical environments, systems must demonstrate stable control of temperature, humidity, airflow, and pressure differentials. parameters crucial for cleanroom integrity and contamination control.

Maintainability focuses on how easily the HVAC system can be inspected, serviced, and maintained without disrupting pharmaceutical operations. In practice, maintainable design means locating critical components in accessible positions and designing systems to allow easy inspection and cleaning. Successful preventative maintenance is essential and is something BES takes extremely seriously.

As BES designs are carried out in a 3D environment, BES carry out detailed commissioning & maintainability reviews during the design process to ensure systems can be successfully commissioned, validated and maintained. This includes ensuring equipment essential for commissioning activities are easily accessible, including valves, dampers, sensors and other control devices. For complex cleanrooms, CFD is also utilised during design to simulate airflow conditions in cleanrooms, allowing BES designers to validate performance virtually before construction. This approach increases the likelihood that real-world commissioning results align with design intent, reducing costly redesigns and validation delays.

Ultimately, designing for both commissionability and maintainability go hand in glove and if done well reduce construction & lifecycle risk. Systems that are easy to commission are inherently easier to regulate, validate, and maintain.

By carrying out these reviews in the 3D environment during the design process, BES can deliver the stable, compliant environments essential to safe and efficient pharmaceutical manufacturing.
