BREEAM: Enhancing Sustainability in the Built Environment
BREEAM (Building Research Establishment Environmental Assessment Method) is the world’s leading environmental assessment method and rating system for buildings. With over 200,000 certified buildings worldwide, BREEAM aims to promote sustainability and reduce the environmental impact associated with the built environment. This article delves into the BREEAM assessment process, its components, and its significance for modern construction.
Understanding the BREEAM Rating System
The BREEAM rating system evaluates the sustainability of a building across several criteria, including:
- Energy Efficiency: Measures energy consumption and encourages the use of renewable energy sources.
- Water Usage: Assesses the management of water resources and promotes water-efficient technologies.
- Materials: Examines the source and sustainability of building materials used.
- Indoor Environmental Quality: Evaluates the indoor comfort conditions, including air quality and lighting.
- Site Management: Encourages sustainable practices in the construction process and site management.
The BREEAM Assessment Process
A full BREEAM New Construction 2011 assessment is undertaken in four to five stages, which may vary based on the timing of the assessor’s appointment. The stages include:

- Registration: Essential for establishing a project’s commitment to sustainable practices.
- Pre-assessment: Provides initial guidance to identify potential sustainability issues and solutions.
- Initial Guidance/Design Stage Assessment: Evaluates preliminary designs and ensures compliance with BREEAM standards.
- Construction: Involves monitoring the building process to ensure adherence to BREEAM criteria.
- Post-Construction Review/Final Certification: A final evaluation that awards certification based on performance and compliance.
The Importance of BREEAM Certification
Achieving BREEAM certification is beneficial for various stakeholders, including:
- Developers: Enhances marketability and increases property value.
- Occupants: Provides a healthier living or working environment through improved indoor air quality and comfort.
- The Community: Contributes to broader sustainability goals by reducing carbon footprints and promoting responsible resource use.
- Investors: Increases the attractiveness of projects through the demonstration of sustainable practices and compliance with regulations.
Global Recognition and Impact
Since its inception over two decades ago, BREEAM has made a substantial impact on the global construction industry. It has shaped best practices and encouraged innovation in sustainable building design. The certification is recognized internationally, making it a benchmark for green building in many countries.
Challenges and Future of BREEAM
While BREEAM has significantly advanced sustainability within construction, several challenges remain:
- Adaptation to Changing Regulations: The construction industry must continually adapt to evolving environmental regulations and standards.
- Awareness and Education: Increasing knowledge among stakeholders about the benefits and processes associated with BREEAM is essential.
- Integration with New Technologies: Incorporating emerging technologies in assessments can enhance the effectiveness of the certification.
As the built environment aims for greater sustainability, BREEAM will likely evolve, continuing to set the standard for environmental performance in buildings. Its ongoing development will respond to emerging challenges and opportunities, ensuring that it remains relevant in a changing world.
