What is EN ISO 20107:2011?

EN ISO 20107:2011 is a technical standard that provides guidelines and requirements for the evaluation of thermal bridging in buildings. In simple terms, it focuses on the measurement and analysis of heat transfer through structural elements such as walls, roofs, and floors. This standard plays a crucial role in ensuring energy efficiency and thermal comfort in buildings.

The Importance of EN ISO 20107:2011

Thermal bridging refers to areas in a building's envelope where the insulation is compromised, leading to increased heat loss or gain. These bridging points can significantly impact energy consumption and indoor climate. The purpose of EN ISO 20107:2011 is to identify and quantify these thermal bridges, enabling architects, engineers, and construction professionals to make informed decisions regarding insulation placement and design.

Key Requirements of EN ISO 20107:2011

EN ISO 20107:2011 establishes a comprehensive set of guidelines for conducting thermal bridge coefficient measurements and calculations. Its main requirements include:

Defining the scope of the evaluation: The standard outlines what needs to be considered when assessing thermal bridges, including factors such as climatic conditions, interior air temperatures, and materials used.

Measurement methods: EN ISO 20107:2011 sets out approved experimental procedures for measuring thermal bridge coefficients. It specifies the use of high-precision equipment and data analysis techniques to ensure accurate results.

Data interpretation and reporting: The standard provides guidelines on how to interpret test data and calculate overall thermal performance based on the measured coefficients. It also specifies the information that needs to be included in the final reports.

Benefits of EN ISO 20107:2011 Compliance

Complying with EN ISO 20107:2011 brings several benefits, both for building occupants and stakeholders involved in construction:

Improved energy efficiency: By identifying and addressing thermal bridges, buildings can reduce energy consumption for heating and cooling, leading to lower utility bills and reduced environmental impact.

Enhanced thermal comfort: Proper insulation and elimination of thermal bridges result in more consistent indoor temperatures, reducing cold spots or heat infiltration, and ensuring a comfortable living or working environment.

Compliance with regulations: Many countries have adopted EN ISO 20107:2011 as a mandatory standard for building certifications. Compliance is necessary to meet legal requirements and obtain permits or certifications.

In conclusion, EN ISO 20107:2011 provides essential guidelines and requirements for evaluating and addressing thermal bridging in buildings. Adhering to this standard is crucial for promoting energy efficiency, improving thermal comfort, and meeting regulatory compliance. By following the measurement methods and reporting procedures outlined in EN ISO 20107:2011, professionals in the construction industry can ensure better insulation design and create sustainable buildings for the future.
