What is EN ISO 11855:2019?

EN ISO 11855:2019 is a technical standard developed by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO). It provides guidelines and requirements for designing and calculating the energy performance of buildings. The standard focuses on the design of heating and cooling systems and aims to optimize energy usage, reduce carbon emissions, and enhance the overall efficiency of buildings.

Scope of EN ISO 11855:2019

The scope of EN ISO 11855:2019 covers various aspects related to the energy performance of buildings. It includes requirements for the heat generation and distribution systems, such as central heating systems, radiators, underfloor heating, and heat pump installations. The standard also addresses calculations for the design of cooling systems, including air conditioning and ventilation systems.

In addition, EN ISO 11855:2019 provides guidelines for measuring and evaluating the energy performance of buildings. It outlines the methods for determining thermal characteristics, heat losses, and gains in buildings. These measurements are essential for assessing a building's energy efficiency and identifying areas where improvements can be made.

Benefits of EN ISO 11855:2019

Implementing the guidelines outlined in EN ISO 11855:2019 offers several benefits for both building owners and occupants. Firstly, it helps to improve energy efficiency, leading to reduced energy consumption and lower utility costs. By optimizing the design and operation of heating and cooling systems, unnecessary energy waste can be minimized.

Moreover, the standard promotes sustainable practices and reduces environmental impact. By reducing energy consumption, buildings contribute to the global effort to combat climate change and decrease greenhouse gas emissions. This becomes increasingly important in the face of growing concerns about environmental sustainability.

Compliance with EN ISO 11855:2019

Building professionals, including architects, engineers, and contractors, should ensure that their designs and installations comply with EN ISO 11855:2019. By following the guidelines outlined in the standard, they can create buildings that are energy-efficient, sustainable, and comfortable for occupants.

It is also crucial for building owners and facility managers to prioritize compliance with this standard. Regular inspections and maintenance of heating and cooling systems can help identify issues and prevent energy waste. Adhering to EN ISO 11855:2019 can ultimately lead to long-term cost savings and a positive environmental impact.
