What is BREEAM in Construction?
In the realm of construction, sustainability and environmental responsibility have become paramount considerations. One of the most widely recognized standards for assessing the environmental performance of buildings is BREEAM (Building Research Establishment Environmental Assessment Method). BREEAM provides a framework for evaluating the sustainability of buildings, helping developers, architects, and engineers design and construct structures that minimize their environmental impact. This article offers a detailed exploration of BREEAM in construction, covering its origins, assessment criteria, benefits, and its impact on the construction industry.

Understanding BREEAM
BREEAM is a leading sustainability assessment method for master planning projects, infrastructure, and buildings. It recognizes and reflects the value in higher-performing assets across the built environment lifecycle, from new construction to in-use and refurbishment. Developed by the Building Research Establishment (BRE) in the United Kingdom, BREEAM is used worldwide to promote sustainable building practices and improve environmental performance.
Origins and Development
BREEAM was first launched in 1990, making it the world’s longest-established method of assessing, rating, and certifying the sustainability of buildings. Over the years, BREEAM has evolved to address the increasing demand for sustainable construction practices and to incorporate new technologies and methodologies. Today, it is widely regarded as a benchmark for sustainability in the built environment.
BREEAM Assessment Criteria
BREEAM assessments are carried out by independent licensed assessors who evaluate a building’s performance against a range of criteria. These criteria cover a variety of environmental issues, divided into several categories, each contributing to a building’s overall BREEAM score. The primary categories include:
- Energy: Evaluating energy efficiency and the use of renewable energy sources. This category assesses a building’s energy consumption and its carbon emissions.
- Water: Assessing water efficiency and management, including the use of water-saving fixtures and systems for reducing water consumption.
- Materials: Evaluating the environmental impact of materials used in construction, including their sourcing, durability, and recyclability.
- Waste: Assessing waste management practices, including the reduction, reuse, and recycling of construction waste.
- Health and Wellbeing: Evaluating indoor environmental quality, including air quality, lighting, acoustics, and thermal comfort, to ensure occupant wellbeing.
- Pollution: Assessing measures to reduce pollution, including the management of noise, air, water, and light pollution.
- Transport: Evaluating access to sustainable transport options and facilities that encourage the use of public transport, cycling, and walking.
- Ecology: Assessing the building’s impact on local ecosystems and biodiversity, including measures to enhance and protect natural habitats.
- Management: Evaluating the management processes and strategies in place to ensure the building operates sustainably throughout its lifecycle.
BREEAM Rating Levels
Based on the assessment, buildings are awarded a BREEAM rating that reflects their environmental performance. The rating levels are:
- Pass: Acknowledges that basic sustainability measures are in place.
- Good: Demonstrates a good standard of sustainability performance.
- Very Good: Indicates advanced sustainability practices and performance.
- Excellent: Reflects best practice and exemplary performance in sustainability.
- Outstanding: Represents an exceptional level of sustainability achievement, going beyond industry standards.
Benefits of BREEAM in Construction
The implementation of BREEAM in construction offers numerous benefits for developers, occupants, and the environment:
Enhanced Sustainability
BREEAM encourages the adoption of sustainable building practices, resulting in reduced environmental impact. By promoting energy efficiency, water conservation, and waste reduction, BREEAM helps minimize the ecological footprint of buildings.
Improved Building Performance
BREEAM-certified buildings are designed to perform better in terms of energy efficiency, resource management, and occupant comfort. This can lead to lower operational costs, improved indoor air quality, and enhanced occupant satisfaction.
Increased Marketability
Buildings with a BREEAM certification are often more attractive to investors, tenants, and buyers due to their demonstrated commitment to sustainability. This can lead to higher property values and increased demand in the real estate market.
Regulatory Compliance
BREEAM provides a framework for meeting and exceeding regulatory requirements related to environmental performance. By aligning with BREEAM standards, developers can ensure compliance with local and national regulations.
Future-Proofing Investments
BREEAM helps future-proof investments by encouraging the use of sustainable practices and technologies that are likely to remain relevant as environmental regulations and market expectations evolve.
Challenges in Implementing BREEAM
While BREEAM offers significant advantages, its implementation can present challenges:
Cost Considerations
Achieving a high BREEAM rating may require additional investment in sustainable technologies and materials. However, these costs can be offset by long-term savings in operational expenses and increased property value.
Complexity of Assessment
The BREEAM assessment process can be complex, requiring detailed documentation and coordination among project stakeholders. Engaging experienced BREEAM assessors and consultants can help navigate this complexity.
Balancing Competing Priorities
Developers must balance sustainability goals with other project priorities, such as budget constraints and design requirements. Effective planning and collaboration are essential to achieving a successful balance.
BREEAM’s Impact on the Construction Industry
BREEAM has had a profound impact on the construction industry, driving innovation and encouraging the adoption of sustainable practices. Some key impacts include:
Promoting Green Building Practices
BREEAM has been instrumental in promoting green building practices, encouraging developers to prioritize sustainability in their projects. This has led to the widespread adoption of energy-efficient technologies, sustainable materials, and eco-friendly design strategies.
Influencing Policy and Regulation
BREEAM has influenced policy and regulation by providing a benchmark for sustainability performance. Governments and regulatory bodies often reference BREEAM standards when developing environmental policies and building codes.
Raising Awareness and Education
BREEAM has raised awareness about the importance of sustainability in construction, educating industry professionals and the public about the benefits of green building practices. This has contributed to a cultural shift towards sustainability in the built environment.
Conclusion
BREEAM is a cornerstone of sustainable construction, providing a comprehensive framework for assessing and improving the environmental performance of buildings. By addressing key sustainability issues such as energy efficiency, water conservation, and waste management, BREEAM helps developers create buildings that minimize their ecological impact and enhance occupant wellbeing. Despite the challenges associated with implementation, the benefits of BREEAM in terms of sustainability, marketability, and compliance make it an invaluable tool for the construction industry. As we continue to prioritize environmental responsibility, BREEAM will play a crucial role in shaping the future of sustainable construction.
