Comprehensive Guide to EN 308 Heat Recovery Ventilator Thermal Efficiency Evaluation Laboratory Testing Service

Provided by Eurolab

Standard-Related Information

EN 308 is a European Standard that specifies the requirements for heat recovery ventilators (HRV) in buildings, focusing on their thermal efficiency evaluation. This standard is part of the CEN/TC 156 series, which deals with ventilation and air conditioning systems in buildings.

International and National Standards

The international standards relevant to EN 308 include:

  • ISO 13789:2010(E) - Thermal performance of building components - Dynamic thermal characteristics

  • ASTM E1743-07 - Standard Practice for Estimating the Energy Savings from Improving Building Insulation

    • National standards, such as those in Germany (DIN V 18599), Italy (UNI EN 308), and France (NF EN 308), also govern HRV thermal efficiency evaluation.

    Standard Development Organizations

    The development of international standards is coordinated by organizations like the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM). National standard development organizations, such as DIN in Germany and AFNOR in France, contribute to the creation and adoption of national standards.

    Evolution of Standards

    Standards evolve through a continuous process of review and revision. This ensures that they remain relevant to changing industry needs and technological advancements.

    Standard Numbers and Scope

    Some key standard numbers related to EN 308 are:

  • ISO 13789:2010(E) - Thermal performance of building components - Dynamic thermal characteristics

  • ASTM E1743-07 - Standard Practice for Estimating the Energy Savings from Improving Building Insulation

  • EN 308:2008 - Ventilation for buildings - Performance requirements for ventilation systems with a mechanical heat recovery

    • Industry-Specific Compliance Requirements

    Different industries have varying compliance requirements for EN 308 testing:

  • Residential buildings must meet minimum thermal efficiency requirements to ensure occupant comfort and energy savings.

  • Commercial buildings may require more stringent standards due to higher occupancy levels and energy usage.

    • Standard-Related Risks and Consequences

    Failure to comply with EN 308 can lead to reduced building performance, increased energy consumption, and decreased occupant comfort. This may result in:

  • Reduced property value

  • Increased maintenance costs

    Testing Timeframes and Duration

    The testing process typically takes several days, depending on the complexity of the test setup and the number of samples being tested.

    Sample Size Requirements and Statistical Considerations

    A minimum sample size of 3-5 units per manufacturer is recommended to ensure statistically significant results.

    Test Reporting and Documentation

    Eurolab provides comprehensive test reports detailing:

  • Test methodology

  • Results

  • Conclusion

    • The report format follows the standard specified by EN 308, ensuring clarity and ease of interpretation for stakeholders.

    Why This Test Should Be Performed

    EN 308 testing is essential for several reasons:

  • Risk Assessment and Mitigation: Testing ensures compliance with regulatory requirements, reducing the risk of fines or penalties.

  • Quality Assurance and Compliance Benefits: Meeting standard requirements demonstrates a commitment to quality and safety, improving customer confidence.

  • Competitive Advantages: Companies that meet EN 308 standards can differentiate themselves in the market, increasing their competitiveness.

  • Energy Savings: Testing ensures that HRVs operate efficiently, reducing energy consumption and costs.

    • Conclusion

    EN 308 testing is critical for ensuring the thermal efficiency of heat recovery ventilators. Eurolabs comprehensive guide provides an overview of the standard, its requirements, and the benefits of testing. By understanding the importance of EN 308, manufacturers can ensure compliance with regulatory standards and provide high-quality products that meet customer expectations.
