💡 In 2026, cleanrooms in Vietnam must be engineered for efficiency, compliance, and cost-effectiveness — not just construction.

2. Why Clean Room Design Matters More Than Ever in 2026

2.1 Regulatory Pressure Is Increasing

Vietnam’s MoH and WHO-GMP audits focus on:

• Contamination control
• Airflow direction
• Pressure cascade
• HVAC validation
• Differentiated zoning
• Documentation traceability

2.2 Risk of Cross-Contamination

Poor clean room design can lead to:

• Batch failures
• Product recalls
• Line shutdowns
• Regulatory penalties

2.3 Growth in High-Risk Products

Vietnam is expanding in:

• Sterile injectables
• Vaccines
• Hormonal products
• Biologics
• Oncology formulations

These require robust cleanrooms with air cleanliness up to ISO Class 5.

2.4 Sustainability Goals

Modern clean room design saves:

• Energy
• Maintenance cost
• Operational time

3. Best Practices in Clean Room Design Consultancy Vietnam (2026 Edition)

Let’s explore the most important 2026 design principles.

3.1 Start with a Clear URS (User Requirement Specification)

Every cleanroom project must begin with a strong URS.

Should include:

• Cleanroom classification
• HVAC requirements
• Temperature & RH setpoints
• Type of product (sterile, non-sterile, biological)
• Material flow
• Personnel flow
• Equipment requirements
• Zoning map
• Regulatory standards
• Validation expectations

💡 A detailed URS reduces 80% of future design errors.

3.2 Follow ISO 14644 Standards (Updated)

Cleanroom classification in 2026 must comply with:

• ISO 14644-1 (Classification)
• ISO 14644-2 (Monitoring)
• ISO 14644-3 (Testing & Validation)

Typical pharma classifications:

Vietnamese plants must follow these strictly to avoid WHO observations.

3.3 Implement a Strong HVAC Design

HVAC is the heart of clean room design consultancy Vietnam.

Key HVAC parameters:

• Air Change Per Hour (ACPH)
• Pressure differentials
• Airflow patterns
• HEPA filter efficiency
• Fresh air ratio
• Temperature & RH
• Recovery time

HVAC Best Practices 2026

• Maintain pressure cascade to prevent cross-contamination
• Use terminal HEPA filters (H14)
• Ensure airflow visualization (smoke studies) is validated
• Use VFDs (Variable Frequency Drives) to optimize energy
• Design proper return air ducts

💡 WHO inspectors in Vietnam heavily check pressure differentials.

3.4 Design for Material & Personnel Flow

Cross-contamination is a major risk in GMP facilities.

Material Flow Best Practices:

• Separate entry & exit
• Pass boxes with interlocking
• Dedicated washing area

Personnel Flow Best Practices:

• Gowning rooms with 3-stage entry
• Defined hand washing zones
• Color-coded gowning

3.5 Use GMP-Compliant Materials

All surfaces should be:

• Non-porous
• Non-shedding
• Chemical resistant
• Easy to clean

Common choices:

• PUF panels
• Epoxy flooring
• Stainless-steel accessories
• GMP-compliant doors

3.6 Build for Validation From Day One

Clean room design must support:

• IQ/OQ/PQ qualification
• HVAC system validation
• Airflow visualization studies
• HEPA integrity testing

Consultants must ensure:

• Sampling ports
• Calibration points
• Accessible filter locations
• Proper duct design

3.7 Integrate Environmental Monitoring Systems (EMS/BMS)

Modern cleanrooms use:

• 24×7 monitoring
• Real-time data logging
• Alarm systems
• Trend analysis

EMS should monitor:

• Airborne particles
• Differential pressure
• Temperature & RH
• Air velocity
• Filter conditions

3.8 Adopt Energy-Efficient Clean Room Design

Energy can consume 60–75% of operational cost.

Energy-saving methods:

• Heat recovery systems
• VFD-driven AHUs
• LED panels
• Intelligent air recirculation design
• Smart HVAC zoning

4. Common Clean Room Design Mistakes in Vietnam (and How to Avoid Them)

❌ Wrong pressure cascade

❌ Poor zoning planning

❌ Oversized HVAC units

❌ Inadequate return air ducts

❌ Non-GMP flooring choices
