In the realm of building biology, the quest for a healthier home environment has never been more paramount. As we strive to create sanctuaries that nurture our wellbeing, the significance of selecting natural and non-toxic building materials becomes undeniable. These materials are the foundation of “breathable homes” – living spaces designed to promote superior indoor air quality and, by extension, our health. Let’s dive into the science that underpins this crucial aspect of architecture.

The Cornerstone of Building Biology

Building biology is an interdisciplinary field that examines the built environment’s impact on human health and the natural ecosystem. It posits that a home should not only be aesthetically pleasing and structurally sound but also conducive to its inhabitants’ health. This principle guides architects and building biologists in choosing materials that enhance indoor air quality – an essential component of a healthy home.

Why Indoor Air Quality Matters

Modern homes are often sealed tight for energy efficiency, trapping pollutants inside (YourHome 2014). The World Health Organisation (WHO 2024) has highlighted the risks of poor indoor air quality, linking it to respiratory conditions, allergies and even heart disease. Here, the philosophy of building biology offers a remedy: by incorporating breathable, natural materials, we can mitigate these health risks (Simonson et al. 2004).

The Science of Breathable Materials

Breathable materials work by allowing moisture to pass through them, reducing the risk of mould growth and maintaining a balance of humidity that is crucial for healthy indoor air (Simonson et al. 2004). Materials such as clay, lime plaster, and certain wood types possess hygroscopic properties, meaning they can absorb and release moisture naturally, which helps to purify the air and regulate indoor climates.

Moreover, these natural materials are typically low in volatile organic compounds (VOCs), chemicals often found in synthetic building materials (particularly adhesives, paints and fabrics) that can off-gas into your home environment (YourHome 2014). Reducing VOC levels is essential for maintaining clean air and protecting your family’s health (YourHome 2014).

Exploring Natural and Non-toxic Materials

1. Clay Plaster: An excellent material for maintaining air quality, clay plaster can absorb toxins and odours, releasing them back into the atmosphere harmlessly.
2. Natural Wood: Choosing untreated or naturally treated wood can significantly reduce exposure to harmful chemicals, enhancing your home’s breathability.
3. Cork and Bamboo: Renewable, sustainable, and with low VOC emissions, both cork and bamboo offer fantastic alternatives to traditional flooring options.
4. Wool Insulation: A natural fibre, wool, is not only an effective insulator but also capable of managing humidity and purifying indoor air by absorbing pollutants.

Incorporating Breathable Materials into Your Home

Planning a home that breathes requires a thoughtful approach to architecture and material selection. It’s not merely about aesthetics; it’s about crafting spaces that enhance wellbeing. A building biologist or well-informed architect can provide tailored advice on integrating these materials into your home’s design.

Summary

The journey towards a healthier home environment is a conscious choice that begins with understanding the materials that surround us. By embracing the principles of building biology and opting for natural, non-toxic building materials, we can significantly improve our indoor air quality and, consequently, our health and wellbeing.
