LEED and BREEAM: Focus on building certification

LEED, which stands for "Leadership in Energy and Environmental Design", is an internationally recognised certification system developed by the U.S. Green Building Council (USGBC). It aims to promote environmentally friendly and resource-conserving buildings.

LEED evaluates the Sustainability of buildings in various categories, including site selection, water efficiency, energy and atmosphere, materials and resources, and interior quality. The Certification is awarded at different levels: Certified, Silver, Gold and Platinum, depending on the number of points achieved. BREEAMor "Building Research Establishment Environmental Assessment Method", is a similar certification system that originated in the United Kingdom.

It was introduced in 1990 and is one of the oldest and best-known systems for assessing the environmental performance of buildings. BREEAM evaluates buildings in categories such as management, health and well-being, energy, transport, water, materials, waste, land use and ecological diversity as well as environmental pollution. Also BREEAM offers various certification levels, including Pass, Good, Very Good, Excellent and Outstanding.

Key Takeaways

• LEED and BREEAM are certification systems for sustainable buildings.
• Building certification is important for the Sustainability and environmental friendliness of buildings.
• LEED and BREEAM differ in their assessment criteria and focal points.
• A LEEDCertification offers Advantages such as energy savings and improved interior quality.
• BREEAM certification offers Advantages such as lower operating costs and improved environmental performance.

The importance of building certification

Environmental friendliness and energy efficiency

The certification enables developers and owners to prove that their buildings are environmentally friendly and meet the latest standards for Energy efficiency and resource conservation.

Advantages for companies and users

This can not only improve the image of the company, but also increase the value of the property. In addition, building certification also has a positive impact on the health and well-being of users. Studies have shown that certified buildings often offer better air quality, more daylight and more pleasant room acoustics.

Sustainability and the future

These factors help to increase user productivity and promote general well-being. At a time when the effects of climate change are becoming ever more apparent, the importance of sustainable construction and the associated certification should not be underestimated.

The differences between LEED and BREEAM

Although both LEED and BREEAM pursue similar objectives, there are significant differences in their approaches and assessment methods. A key difference lies in their geographical focus: LEED is most prevalent in North America, while BREEAM originated in the UK and is popular in Europe and other parts of the world. These different origins lead to varying emphases in the assessment criteria.

Another difference lies in the structure of the rating systems. LEED uses a points system in which projects can collect points for various sustainable practices. The total number of points determines the certification level.

BREEAM, on the other hand, rates projects on a scale from "Pass" to "Outstanding", with the rating based on a combination of points and qualitative criteria. Criteria based. These differences in methodology can be crucial for clients and architects when deciding which system is best suited to their project.

The advantages of LEED certification

LEED certification offers numerous advantages for developers and owners. One of the most outstanding benefits is the ability to reduce operating costs. Through the Implementation energy-efficient systems and sustainable practices, energy costs can be significantly reduced.

Studies have shown that LEED-certified buildings consume on average 30 % less energy than conventional buildings. This not only leads to cost savings, but also to a lower environmental impact. Another advantage is the increased market appeal of LEED-certified buildings.

In many markets, tenants and buyers are increasingly interested in sustainable properties. LEED certification can therefore serve as a selling point and help to achieve higher rents or sales prices. Certification can also facilitate access to government subsidies or tax incentives, which brings additional financial benefits.

The advantages of BREEAM certification

BREEAM also offers a wide range of benefits for building owners and developers. A key benefit is the comprehensive assessment of a building's environmental performance across different categories. This enables a holistic view of the project and promotes the integration of sustainable practices in all phases of the construction process.

This comprehensive approach enables building owners to ensure that all aspects of sustainability are taken into account. In addition, BREEAM certification can also Risk of legal problems. In many countries, there are increasingly strict regulations regarding environmental protection in the Construction.

BREEAM certification can serve as proof that a building fulfils or even exceeds the applicable regulations. This can avoid potential legal disputes and boost the confidence of investors and tenants.

The requirements for LEED certification

In order to obtain LEED certification, projects must fulfil a number of requirements that are divided into different categories. The basic requirements include compliance with certain standards for energy efficiency and water management. For example, buildings must be designed to minimise energy consumption while optimising water consumption.

This can be achieved by using energy-efficient appliances, intelligent building technology and water-saving fittings. In addition, projects must also fulfil material selection requirements. LEED promotes the use of recycled materials and materials with a low environmental impact.

Consideration of the life cycle costs of materials also plays a role. In addition, builders must demonstrate that they apply environmentally friendly practices throughout the construction process, including waste management and construction site organisation.

The requirements for BREEAM certification

The requirements for BREEAM certification are also diverse and cover various aspects of the construction process. A central point is the management of the project during the planning and construction phase. BREEAM attaches great importance to clear documentation of all steps and the involvement of all relevant stakeholders in the process.

This not only promotes the Transparencybut also the cooperation between architects, engineers and clients. Another important aspect is the requirements for the health and well-being of users. For example, BREEAM assesses the quality of indoor air as well as access to natural light and views to the outside.

These factors are crucial for the well-being of users and can have a positive impact on their productivity. In addition Criteria such as sound insulation and thermal comfort are taken into account.

Which certification system is right for your building?

The decision between LEED and BREEAM depends on a number of factors, including location, project type and the client's specific objectives. For example, if a project is located in North America or if the client already has experience with LEED, this system may be the better choice. LEED provides a clear structure with a point system that makes it easier to measure progress and set goals.

On the other hand, BREEAM may be more suitable for projects in the UK or Europe, especially if a more comprehensive assessment of environmental performance is desired. BREEAM takes into account not only technical aspects, but also social factors such as occupant well-being. Ultimately, the choice of certification scheme should be based on a thorough analysis of the specific requirements of the project and the client's long-term objectives in terms of sustainability and environmental responsibility.
