How to stop heat and money from going out of the window using standards?

During winter many households face high energy bills, especially when the energy used to keep their house warm comes from fossil fuels. Although it is irrefutable that we need to move towards clean and renewable energy sources, it is also true that we could use non-renewable sources more efficiently. 

One of the biggest challenges that many buildings face in Europe is that they are badly isolated, either because they are old or because they are not well constructed, and therefore, the heat in winter and the AC in summer easily go to waste. Addressing the inefficiency in energy consumption and promoting sustainable practices in building infrastructure is a critical step toward mitigating the environmental impact of excessive energy use. 

The European Union has several initiatives to address these challenges. The Energy Performance of Buildings Directive (EPBD) sets out the minimum energy performance requirements for new and existing buildings through renovations. The EU Directive 2018/844 mandates member states to establish energy performance certificates for buildings, providing transparent information to owners and tenants about the energy efficiency of their properties. 

Moreover, the EU's Renovation Wave Strategy aims to accelerate the pace of renovations. The strategy focuses on making buildings not only energy-efficient but also climate-resilient. Financial incentives and support mechanisms are provided to encourage property owners to invest in energy-efficient renovations, fostering a transition towards more sustainable and environmentally friendly buildings. 

The initiatives are supported through the implementation of standards. One notable CEN standard in this context is EN 14351-1, which focuses on windows and external pedestrian door sets. This standard establishes performance characteristics and requirements, including thermal insulation, ensuring that these elements contribute positively to the energy efficiency of a building. 

On his side, ISO has also contributed to the cause with standards like ISO 12567-1, which addresses the thermal performance of windows, doors, and shutters. Compliance with such standards ensures that these building elements meet international benchmarks for energy efficiency, providing a harmonized approach to sustainable construction practices. 

IEC standards, such as IEC 60335-2-40, focus on the safety and performance of electric heat pumps, including those used for heating and cooling in buildings. These standards are crucial in ensuring the reliability and safety of energy-related products, contributing to overall energy efficiency.  

The role of these standards in promoting better isolation of doors and windows is paramount. By providing clear guidelines and performance requirements, they empower builders, manufacturers, and consumers to make informed decisions that align with the EU's vision for a more sustainable future. 

The integration of better-isolated windows and doors into building design is not just a matter of comfort; it is a fundamental step towards achieving energy efficiency goals. The regulations and standards put forth by the EU, CEN, ISO, and IEC provide the necessary framework to ensure that construction practices align with sustainability objectives. As households grapple with high energy bills, the implementation of these standards becomes increasingly important, creating a pathway to a more energy-efficient and environmentally conscious future.
