What is BS EN 15663-2011?

BS EN 15663-2011 is a technical standard that specifies the requirements for energy performance in buildings. This standard was developed by the European Committee for Standardization (CEN) and provides guidelines for measuring and reporting the energy efficiency of buildings.

Understanding the purpose

The main purpose of BS EN 15663-2011 is to establish a common framework for assessing the energy performance of buildings. It sets out the procedures and methodologies for evaluating energy consumption, thermal performance, and indoor environmental quality. By adhering to these standards, building owners, operators, and occupants can gain a better understanding of their energy usage and make informed decisions regarding energy efficiency improvements.

Main requirements and criteria

This standard outlines specific requirements and criteria for assessing different aspects of a building's energy performance. Some of the key areas it covers include:

Energy consumption measurement: BS EN 15663-2011 provides guidelines on how to accurately measure and record energy use in buildings. This includes both primary energy consumed by the building itself and secondary energy used during its operation.

Thermal performance: The standard also addresses the thermal properties of buildings, such as insulation, air tightness, and solar gain. It specifies the methods for calculating heat transfer coefficients and determining the thermal comfort conditions inside the building.

Indoor environmental quality: BS EN 15663-2011 considers the factors that affect the indoor environment, including ventilation, air quality, lighting, and acoustics. It establishes parameters for assessing these qualities and ensuring occupant comfort and well-being.

Benefits and importance

Complying with BS EN 15663-2011 offers several benefits for building owners, occupants, and the environment. Firstly, it provides a standardized approach to assessing energy performance, allowing for reliable comparisons between different buildings. This promotes transparency and helps identify areas for improvement.

Secondly, by implementing the recommendations of this standard, building owners can reduce their energy consumption and, consequently, their carbon footprint. The guidelines suggest measures for increasing energy efficiency, such as optimizing insulation, integrating renewable energy sources, and improving systems for heating, cooling, and lighting.

Additionally, BS EN 15663-2011 plays a crucial role in achieving sustainability goals and meeting legislative requirements. Many countries have adopted similar standards, making it essential for businesses and organizations to comply with them in order to stay competitive and ensure a sustainable future.

In conclusion, BS EN 15663-2011 is a vital technical standard that sets the requirements for measuring and reporting energy performance in buildings. Its guidelines help assess energy consumption, thermal properties, and indoor environmental quality. By adhering to these standards, building stakeholders can make informed decisions to improve energy efficiency, reduce environmental impact, and achieve sustainable development.
