What is EN ISO 11855-1:2019

EN ISO 11855-1:2019 is a technical standard that specifies the requirements for thermal isolation in buildings. It provides guidelines and criteria for designing, installing, and evaluating the thermal performance of building elements such as walls, roofs, floors, windows, and doors. The standard aims to ensure energy efficiency, reduce heat loss, and enhance thermal comfort within buildings.

Key Requirements of EN ISO 11855-1:2019

The standard outlines several key requirements that need to be met in order to comply with EN ISO 11855-1:2019. These include:

The use of suitable insulation materials with appropriate thermal conductivity values

The prevention of thermal bridging, which can lead to heat loss and reduced energy efficiency

The proper installation of insulation components to avoid gaps or voids that could compromise thermal performance

The consideration of climatic factors such as temperature, humidity, and wind when determining thermal design parameters

The inclusion of insulation thickness calculations based on target U-values

Benefits of Complying with EN ISO 11855-1:2019

Complying with EN ISO 11855-1:2019 offers several benefits for both building owners and occupants. Firstly, it helps to improve energy efficiency by minimizing heat loss through well-insulated building elements. This leads to reduced heating and cooling costs, contributing to cost savings over the long term. Additionally, enhanced thermal comfort is achieved, as properly insulated buildings maintain stable indoor temperatures, reducing the need for additional heating or cooling.

In terms of environmental impact, complying with this standard promotes sustainability by reducing the carbon footprint of buildings. By improving energy efficiency, it helps to lower greenhouse gas emissions associated with heating and cooling systems. Furthermore, compliance often results in better indoor air quality, as effective insulation can help prevent moisture buildup and mold growth.

Another advantage is that compliance with EN ISO 11855-1:2019 can contribute towards meeting building regulations and certification requirements. Many countries have adopted energy efficiency standards, and complying with this international standard can facilitate compliance with local regulations. It can also enhance the market value of a building, as energy-efficient and well-insulated properties are increasingly sought after by investors and tenants.

Conclusion

EN ISO 11855-1:2019 plays a crucial role in ensuring thermal comfort, energy efficiency, and environmental sustainability in buildings. Its guidelines and criteria for thermal isolation help minimize heat loss, promote energy savings, and improve the overall quality of indoor environments. By complying with these standards, building owners and occupants can enjoy benefits such as reduced energy costs, enhanced thermal comfort, and improved market value. Ultimately, adherence to EN ISO 11855-1:2019 contributes to a more sustainable and resilient built environment.
