Building Biology Standards

In an era where sustainable construction and healthy living environments are increasingly prioritized, understanding international building biology standards is more important than ever. These standards not only offer a framework for designing safe and comfortable buildings, but they also support the urgent need for sustainability in today’s built environment.

Moreover, they help address the growing challenges of climate change, rapid urbanization, and health issues linked to poor indoor air quality. As a result, architects, developers, and investors can use these standards as trusted benchmarks for best practices.

In the following sections, we explore several key international building biology standards. Specifically, we highlight their origins, main focus areas, and their role in promoting healthier, more sustainable living and working spaces.

SBM (Standard of Building Biology Measurement)

Originating in Germany in 1999, the SBM is a well-established standard in building biology. It sets strict limits for electromagnetic fields (electrosmog), mold, toxins, and radiation in living spaces. Although it is not legally binding, it forms the foundation for many international projects, especially those focused on creating healthy buildings. Notably, the latest revision — SBM 2024 — incorporates cutting-edge scientific findings to support the healthiest possible environments.

LEED (Leadership in Energy and Environmental Design)

Developed by the US Green Building Council in 1998, LEED is a widely recognized certification system promoting sustainability in over 165 countries. In many cases, LEED certification is a prerequisite for public building projects and eligibility for green loans. Moreover, it covers energy efficiency, air quality, water conservation, and more, following standards like ASHRAE 62.1 for indoor air quality.

WELL Building Standard (Building Biology Standards)

Introduced in 2014, the WELL Building Standard focuses primarily on the well-being of building occupants. As a result, it has become essential in health-centered building design. In fact, WELL is mandatory in some US states and plays a pivotal role in securing green financing. It evaluates factors such as indoor air quality, lighting, and materials — all aimed at enhancing health and comfort.

BREEAM (Building Research Establishment Environmental Assessment Method)

As one of the earliest sustainability standards, BREEAM was launched in the UK in 1990 and has gained global recognition. Particularly in Europe, BREEAM is often required for public building projects and used to secure financial incentives or loans. It places emphasis on energy efficiency and the reduction of volatile organic compounds (VOCs), among other criteria.

MINERGIE (Building Biology Standards)

Originating from Switzerland in 1998, MINERGIE is a national standard that is legally required for many construction projects. Although it is most prominent in Switzerland, the standard is gaining traction in other countries, including Portugal. It focuses on energy efficiency and indoor air quality, with clear limits on consumption and emissions.

Cradle to Cradle Certified™ (Building Biology Standard)

In contrast to other standards, Cradle to Cradle centers on material recyclability and the reduction of toxicity. Since its launch in 2005, it has become increasingly relevant in the context of the circular economy. While not mandatory, Cradle to Cradle certification is becoming a preferred choice in innovative and sustainable architecture.

EN 13779 (European Standard for Indoor Air Quality)

Established in 2007, this standard applies to public buildings throughout the European Union, including Portugal. Specifically, EN 13779 defines permissible levels of CO₂ and particulate matter. Its main goal is to ensure healthy and safe indoor air, particularly in buildings with high occupancy rates.

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 promoted for over 30 years by a variety of standards and organizations. Over time, the push for sustainable construction has gained momentum, highlighting the importance of creating environments that prioritize occupant health and well-being. At Mezzalyn, we fully recognize the significance of adhering to established limits for indoor air quality. Therefore, our assessments and certifications are designed to provide residents with peace of mind regarding their living conditions.

Building Biology Standards

By following rigorous building biology standards, such as the SBM and EN 13779, we can confidently assure that the buildings we evaluate meet the highest benchmarks for healthy living environments. Moreover, our commitment to ecological building practices is not merely about compliance with regulations. Rather, it reflects a deeper responsibility to promote sustainability and public health across the construction industry. As a result, we strive to foster a culture of awareness and accountability in every project we support. Consequently, the spaces we help create are not only environmentally conscious, but also enhance the quality of life for those who inhabit them. Together, we can lead the way toward a healthier and more sustainable built environment.
