EN 12354 Thermal Bridge Effect Measurement in HVAC Systems Laboratory Testing Service: A Comprehensive Guide

EN 12354 is a European standard that governs the measurement of thermal bridge effect in heating, ventilation, and air conditioning (HVAC) systems. This standard is part of the Eurocode series, which provides a framework for designing and constructing buildings that meet energy efficiency and environmental requirements.

Legal and Regulatory Framework

The EN 12354 standard is based on the European Unions (EU) Building Directives, specifically Directive 2010/31/EU, which aims to improve the energy performance of buildings. The standard is also aligned with the EUs Energy Performance of Buildings Directive (EPBD), which requires Member States to ensure that new and existing buildings meet minimum energy efficiency standards.

International and National Standards

EN 12354 is an extension of the ISO 10211:2008 standard, which provides a framework for calculating the thermal bridge effect in building components. The standard also takes into account national regulations and guidelines, such as the UKs Building Regulations (2013) and the German EnEV (German Energy Saving Ordinance).

Standard Development Organizations

The development of EN 12354 was led by the European Committee for Standardization (CEN), which is responsible for creating and maintaining European standards. CEN works closely with other standard development organizations, such as the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM).

Standard Evolution and Updates

Standards evolve over time to reflect changes in technology, regulations, and industry practices. EN 12354 has undergone several updates since its initial publication in 1999, with the latest revision published in 2016.

Specific Standard Numbers and Scope

EN 12354:2016 - Thermal bridges in building design - Heat transfer via the external walls of buildings

Scope:

This standard provides a method for calculating the thermal bridge effect in external walls of buildings. It covers both new and existing buildings, including residential and non-residential structures.

Standard Compliance Requirements

Compliance with EN 12354 is mandatory for new buildings in EU Member States, while existing buildings must comply with the standard by a specified deadline (typically 2023). Industry sectors that require compliance include:

  • Building design and construction

  • HVAC system installation and maintenance

  • Energy efficiency consulting

    • Standard-Related Information Conclusion

    EN 12354 is a critical standard for ensuring energy efficiency in building design, particularly in the context of thermal bridge effect. Its development and evolution reflect the ongoing efforts to improve building performance and environmental sustainability.

    Why EN 12354 Testing is Needed and Required

    Thermal bridges can significantly reduce a buildings energy efficiency, leading to increased heating and cooling costs, as well as potential damage to the building structure. EN 12354 testing helps identify areas where thermal bridges are most likely to occur, allowing designers and builders to take corrective action.

    Business and Technical Reasons for Conducting EN 12354 Testing

    Conducting EN 12354 testing is essential for several reasons:

  • Ensures compliance with EU regulations

  • Improves energy efficiency and reduces costs

  • Increases building durability and lifespan

  • Enhances marketability and competitiveness

    • Consequences of Not Performing EN 12354 Testing

    Failure to conduct EN 12354 testing can result in:

  • Non-compliance with regulatory requirements

  • Reduced energy efficiency and increased costs

  • Potential damage to the building structure

  • Loss of customer confidence and trust

    • Industries and Sectors that Require EN 12354 Testing

    EN 12354 testing is required for various industries, including:

  • Building design and construction

  • HVAC system installation and maintenance

  • Energy efficiency consulting

  • Architecture and engineering firms
