Sustainable building ist ein Konzept, das darauf abzielt, die Umweltauswirkungen von Bauprojekten zu minimieren und gleichzeitig die Lebensqualität der Nutzer zu verbessern. Es umfasst eine Vielzahl von Aspekten, darunter die Auswahl umweltfreundlicher Materialien, die effiziente Nutzung von Energie und Wasser sowie die Schaffung gesunder Innenräume. Die Grundprinzipien des nachhaltigen Bauens basieren auf der Idee, dass Gebäude nicht nur funktionale Räume sind, sondern auch einen positiven Einfluss auf die Umwelt und die Gesellschaft haben sollten.
This means that architects, engineers and clients must always consider the environmental, social and economic impact when planning and executing construction projects. The importance of sustainable construction is increasingly recognised as global challenges such as climate change, resource scarcity and urbanisation become more pressing. In many countries, there are already legal requirements and incentives for sustainable building practices.
Darüber hinaus zeigen zahlreiche Studien, dass nachhaltige Gebäude nicht nur umweltfreundlicher sind, sondern auch wirtschaftliche Advantages bieten, wie geringere Betriebskosten und eine höhere Wertsteigerung. Die Integration von nachhaltigen Praktiken in den Bauprozess ist somit nicht nur eine ethische Verantwortung, sondern auch eine wirtschaftlich sinnvolle Entscheidung.

LEED certification: advantages and requirements
What is LEED certification?
The LEED-Zertifizierung (Leadership in Energy and Environmental Design) ist ein international anerkanntes Bewertungssystem für nachhaltiges Bauen, das von der U.S. Green Building Council (USGBC) entwickelt wurde. LEED bietet eine strukturierte Methode zur Bewertung der Umweltleistung von Gebäuden und fördert die Implementation sustainable practices in the construction industry.
Advantages of LEED certification
A major advantage of LEED certification is the recognition it enjoys at both national and international level. Buildings with LEED certification are often seen as role models for sustainable construction and can therefore significantly improve the image of companies and institutions.
Requirements and categories
The requirements for LEED certification are diverse and include various categories such as site selection, water efficiency, energy and atmosphere, materials and resources, and interior quality. In order to receive LEED certification, building projects must achieve a certain number of points in these categories.
Awarding points and certification levels
Die Punktevergabe erfolgt auf einer Skala von „LEED Certified“ bis „LEED Platinum“, wobei jede Stufe höhere Anforderungen an die Sustainability stellt. Diese Struktur ermöglicht es Bauherren, gezielt Maßnahmen zu ergreifen, um ihre Gebäude umweltfreundlicher zu gestalten und gleichzeitig die Anforderungen der Zertifizierung zu erfüllen.
BREEAM certification: assessment criteria and standards
BREEAM (Building Research Establishment Environmental Assessment Method) ist ein weiteres führendes Bewertungssystem für nachhaltiges Bauen, das ursprünglich in Großbritannien entwickelt wurde. Ähnlich wie LEED zielt BREEAM darauf ab, die Umweltleistung von Gebäuden zu bewerten und zu verbessern. Die BREEAM-Zertifizierung berücksichtigt eine breite Palette von Criteriaincluding Energy efficiency, Wassermanagement, Materialauswahl, Abfallmanagement und ökologische Auswirkungen.
Ein herausragendes Merkmal von BREEAM ist die Berücksichtigung des gesamten Lebenszyklus eines Gebäudes, was bedeutet, dass sowohl die Bauphase als auch der Betrieb und die spätere Entsorgung in die Bewertung einfließen. Die Bewertung erfolgt in Form eines Punktesystems, das es ermöglicht, verschiedene Aspekte der Sustainability zu gewichten. Projekte können in verschiedenen Kategorien zertifiziert werden, darunter „BREEAM Very Good“, „BREEAM Excellent“ und „BREEAM Outstanding“.
The requirements for the individual categories vary depending on the type of building and its use. An important aspect of BREEAM is also the involvement of stakeholders throughout the planning and construction process, which can lead to greater acceptance and better results.
Sustainable building in practice: success stories and examples
| Category | Metric | Example |
|---|---|---|
| Energy efficiency | Reduction of energy consumption by 30% | Passive house in Munich |
| Sustainable materials | Use of recycled building materials around 50% | Office building in Berlin |
| Water efficiency | Reduction in water consumption by 40% | Residential complex in Hamburg |
| Environmentally friendly mobility | 70% of residents use public transport or bicycle | Urban development project in Freiburg |
In practice, there are numerous impressive examples of sustainable construction that demonstrate both innovative approaches and successful implementations. One outstanding example is the Bosco Verticale in Milan, Italy. This residential building consists of two towers, which are planted with over 9,000 trees and 20,000 plants.
This vertical greening not only improves air quality in the city, but also provides a habitat for birds and insects. The project has been honoured with various awards for its sustainable features and has raised awareness of urban greening worldwide. Another notable example is the Bullitt Centre in Seattle, USAwhich is considered one of the most sustainable office buildings in the world.
It was designed according to the principles of the "Living Building Challenge" and produces more energy than it consumes. The building uses solar energy, rainwater harvesting systems and natural ventilation to minimise its ecological footprint. In addition, strict criteria were applied when selecting materials to ensure that no harmful chemicals are used.
The Bullitt Centre serves as a Model für zukünftige Bürogebäude und zeigt eindrucksvoll, wie nachhaltiges Bauen in der Praxis umgesetzt werden kann.
Costs and benefits of LEED and BREEAM certifications
The decision in favour of LEED or BREEAM certification may initially be associated with higher costs, as additional planning and implementation measures are required. However, these investments can be offset by long-term savings in operating costs. Studies have shown that certified buildings often have lower energy costs and enjoy higher tenant satisfaction.
Companies can also strengthen their market position through certification and set themselves apart from the competition. Another financial benefit is the possibility of tax incentives or subsidies for sustainable construction projects in many countries. These incentives can help to reduce the initial costs and increase the profitability of the project.
In addition, LEED or BREEAM certification can increase the value of a building as more and more buyers and tenants attach importance to sustainability. At a time when environmental responsibility is becoming increasingly important, such certification can also serve as a marketing tool.
Sustainable building: Challenges and opportunities
The cost hurdle
One of the biggest hurdles is often the initial cost awareness of investors and building owners. Many see sustainable practices as an additional expense without considering the long-term savings.
Expertise and innovation
There can also be a lack of expertise; not all architects or construction companies are familiar with the latest technologies or materials required for sustainable construction. Nevertheless, these challenges also present opportunities for innovation in the industry. The demand for sustainable solutions is constantly growing, which encourages companies to develop new technologies and optimise existing processes.
Cooperation and knowledge exchange
There is also an increasing trend towards collaboration between different players in the Construction – von Architekten über Ingenieure bis hin zu Bauherren – um gemeinsam nachhaltige Lösungen zu finden. Diese interdisziplinäre Zusammenarbeit kann nicht nur zu besseren Ergebnissen führen, sondern auch den Wissensaustausch fördern.
Although both LEED and BREEAM pursue similar goals - namely the promotion of sustainable building practices - there are some key differences between the two certification systems. LEED originated in the US and has spread internationally, while BREEAM was originally developed in the UK and has a stronger influence there. The assessment methods also differ; while LEED uses a points system based on different categories, BREEAM also takes into account the life cycle of a building more comprehensively.
Ein weiterer Unterschied liegt in den spezifischen Anforderungen der beiden Systeme. LEED legt großen Wert auf Energieeffizienz und Wassermanagement, während BREEAM zusätzlich soziale Aspekte wie den Einfluss auf die Gemeinschaft stärker betont. Trotz dieser Unterschiede haben beide Systeme das gemeinsame Ziel, umweltfreundliche Praktiken im Construction zu fördern und einen positiven Einfluss auf die Umwelt zu erzielen.
Both certifications also offer a variety of resources and training to help builders implement sustainable practices.
The future of sustainable construction: trends and developments
The The future des nachhaltigen Bauens wird voraussichtlich von mehreren Trends geprägt sein, die sowohl technologische Innovationen als auch gesellschaftliche Veränderungen umfassen. Ein bedeutender Trend ist die zunehmende Digitisation in the construction industry. Technologies such as Building Information Modelling (BIM) ermöglichen eine präzisere Planung und Ausführung von Bauprojekten unter Berücksichtigung nachhaltiger Kriterien.
These digital tools can help to use resources more efficiently and minimise waste. Another important aspect is the growing awareness of social sustainability. More and more construction projects are not only taking ecological factors into account, but also social aspects such as community building and quality of life for residents.
This could lead to the increased integration of green spaces in urban areas or the creation of housing that is accessible to different income groups. In addition, regenerative approaches to construction are expected to gain in importance. These concepts aim to not only minimise the ecological footprint of a building, but to actively contribute to improving the environment - be it through CO2 reduction or by creating habitats for flora and fauna.
In combination with existing certification systems such as LEED and BREEAM, this could herald a paradigm shift in the construction industry and set new standards for future projects.
