Global Building Biology Standards
In-Depth Examination of International Building Biology Standards: Understanding Their Foundations, Legal Frameworks, and Impact on Sustainable Construction Practices Across Different Regions
In an era where sustainable construction and healthy living environments are increasingly prioritized, understanding international building biology standards becomes crucial for architects, developers, and investors alike. These standards not only provide a framework for creating buildings that are safe and comfortable for occupants, but they also address the pressing need for sustainability in our built environment. As we face challenges such as climate change, urbanization, and health concerns related to indoor air quality, these established standards serve as benchmarks for best practices in building design and construction. Below, we explore several key international building biology standards, highlighting their origins, focus areas, and significance in promoting healthier spaces.
- SBM (Standard of Building Biology Measurement) Originating in Germany in 1999, the SBM is a well-established standard in building biology that sets strict limits for electromagnetic fields (electrosmog), mold, toxins, and radiation in living spaces. While not legally binding, it forms the foundation for many projects worldwide, including those aimed at creating healthy buildings. The latest revision, SBM 2024, incorporates cutting-edge scientific findings to ensure the healthiest possible environments.
- LEED (Leadership in Energy and Environmental Design) Introduced by the US Green Building Council in 1998, LEED is a widely recognized certification system that promotes sustainability across more than 165 countries. LEED is often a prerequisite for public building projects and green loans. The certification covers energy efficiency, air quality, water conservation, and more, following standards like ASHRAE 62.1 for indoor air quality.
- WELL Building Standard Focusing on the well-being of building occupants, WELL was launched in 2014 and quickly became a critical standard in health-focused building design. It’s mandatory in some US states and plays a pivotal role in securing green loans. WELL evaluates indoor air quality, lighting, and materials to enhance occupant health and comfort.
- BREEAM (Building Research Establishment Environmental Assessment Method) As one of the earliest sustainability standards, BREEAM, established in the UK in 1990, assesses a building’s environmental impact globally. In many European countries, including the UK, BREEAM is required for public projects, especially to secure financial incentives or loans. It emphasizes factors such as energy efficiency and the reduction of volatile organic compounds (VOCs).
- MINERGIE This Swiss-based standard, established in 1998, is legally mandated for many construction projects in Switzerland. Though most prominent in Switzerland, MINERGIE has spread to other countries, including Portugal. Its focus is on energy-efficient buildings, with strict limitations on energy consumption and indoor air quality.
- Cradle to Cradle Certified™ Unlike other standards, Cradle to Cradle promotes the concept of complete material recyclability and toxicity reduction. Launched in 2005, it’s gaining relevance as more projects adopt a circular economy approach. While not legally required, Cradle to Cradle certification is increasingly sought after in sustainable architecture.
- EN 13779 (European Standard for Indoor Air Quality) Introduced in 2007, this standard applies to public buildings across the European Union, including Portugal. EN 13779 specifies maximum permissible levels of CO₂ and particulate matter to ensure safe and healthy indoor environments.

Summary
A Conclusion on the Long-standing Commitment to Ecological and Healthy Building Practices
Ecological and healthy building practices are not a recent phenomenon; in fact, they have been advocated for over 30 years by various standards and organizations. The push for sustainable construction has deep roots, highlighting the importance of creating environments that prioritize occupant health and well-being. At Mezzalyn, we recognize the significance of adhering to established limits for indoor air quality, ensuring that our assessments and certifications provide residents with peace of mind about their living conditions.
By following rigorous standards, such as the SBM and EN 13779, we can confidently assure that the buildings we evaluate meet the highest criteria for a healthy living environment. Our commitment to ecological building practices is not just about compliance; it’s about fostering a culture of sustainability and responsibility in the construction industry. Together, we can create spaces that are not only environmentally friendly but also promote the health and well-being of all who inhabit them.
