Glass in building – Folio interlayers for the manufacturing of laminated glass – EN 17940:2025

EN 17940:2025 is a European standard that outlines the requirements and guidelines for the design, installation, and maintenance of energy performance assessment methods for buildings. This standard is particularly relevant in the context of the European Union’s commitment to improving energy efficiency and reducing greenhouse gas emissions in the building sector.

The scope of EN 17940:2025 encompasses various aspects of energy performance assessment, including the methodologies used to evaluate the energy consumption of buildings, the criteria for determining energy efficiency, and the procedures for conducting energy audits. It is applicable to a wide range of building types, including residential, commercial, and industrial structures, ensuring that all buildings are assessed consistently and effectively.

One of the primary objectives of EN 17940:2025 is to provide a standardized approach to measuring and reporting the energy performance of buildings. This includes guidelines for the calculation of energy consumption, the assessment of energy-saving measures, and the identification of opportunities for improving energy efficiency. By establishing a common framework for energy performance assessment, the standard aims to facilitate transparency and comparability among different buildings and energy performance ratings.

Additionally, EN 17940:2025 emphasizes the importance of integrating renewable energy sources into the energy performance assessment process. It encourages the consideration of renewable energy technologies, such as solar panels and heat pumps, in the evaluation of a building’s overall energy efficiency. This focus on sustainability aligns with the broader goals of the European Union to promote the use of clean energy and reduce reliance on fossil fuels.

The standard also addresses the need for ongoing monitoring and verification of energy performance, highlighting the importance of regular assessments to ensure that buildings continue to meet energy efficiency standards over time. This aspect is crucial for maintaining compliance with regulatory requirements and for achieving long-term energy savings.

In summary, EN 17940:2025 serves as a comprehensive guideline for the energy performance assessment of buildings in Europe. Its focus on standardized methodologies, sustainability, and ongoing monitoring makes it an essential resource for architects, engineers, building owners, and energy auditors. By adhering to the principles outlined in this standard, stakeholders can contribute to the EU’s energy efficiency goals and promote a more sustainable built environment.
