When we think about buildings, we often focus on how they look or how much space they have. But have you ever thought about how a building can affect your health? Or how much energy it takes to build it?
More and more, people are looking for ways to create homes and buildings that are better for both the people who live in them and the planet. This is where healthy and sustainable construction comes in. It’s all about using materials and methods that are safe, long-lasting, and kind to the environment.
In this series, we’ll explore different materials and techniques that help create healthier buildings.
But first, let’s look at what makes a building “healthy” and “sustainable.”
What is a Healthy Building?
A healthy building is one that supports the well-being of the people inside.
Some key things that make a building healthy include:
Good Air Quality – Some paints, glues, and building materials release harmful chemicals into the air. Choosing natural paints and materials with low toxins (VOC-free) helps keep indoor air clean.
Moisture Control – A damp home can lead to mould, which is bad for your health. Materials like limecrete and breathable insulation help control moisture, keeping spaces dry and fresh. This is especially important when considering upgrading existing homes through retrofit.
Comfortable Temperatures – Natural insulation materials, like wood fibre and sheep’s wool, help keep a home warm in winter and cool in summer. This means less need for heating and air conditioning.
Connection to Nature – Homes that allow lots of natural light and have easy access to outdoor spaces can improve mental well-being. Simple design choices, like larger windows or garden connections, can make a big difference.
What is Sustainable Construction?
Sustainable construction means building in a way that reduces harm to the environment but also considering the life cycle of a building. This includes:
Using Low-Carbon Materials – Some building materials, like concrete and steel, take a lot of energy to produce. There are alternatives, such as timber or low-carbon steel, that have a smaller environmental impact.
Reducing Waste – Construction creates a lot of waste, but using reclaimed wood, recycled materials, or modular designs can help cut down on what gets thrown away. Also, these can allow for future de-assembly, improving reuse and recycling of materials.
Energy Efficiency – Designing homes to use less energy, such as including better insulation, solar panels, or energy-efficient windows, makes them more sustainable in the long run.
What’s Next?
This is just an introduction.
I will be exploring some of these materials in more detail in follow up articles, starting with looking at these initial materials;
Hemp-based materials
Limecrete is a breathable, eco-friendly alternative to concrete.
Natural insulation such as wood fibre and wool
Low-VOC paints and caly plaster finishes
Steel-framed buildings
Lime mortar
By making better choices in construction, we can create homes that are healthier to live in and better for the planet.
Whether you’re thinking of building a new home or renovating an old one, small changes can make a big impact.
