Main Story

Building a new home is more than just bricks and mortar, it’s a chance to really nail sustainability and energy efficiency right from the start. Think about it, you’re not just building a house; you’re crafting a living space that reflects your values and, let’s be honest, impacts your wallet. Choosing the right materials, that’s where the magic truly happens. They play a huge part in minimizing your environmental footprint, and in making your space comfy without costing a fortune to run.

So, what are some top-notch materials to consider? Well, here are ten energy-efficient options to get you thinking:

• 1. Precast Concrete: Okay, so concrete gets a bad rap for its carbon footprint, and fair enough. But precast is different. It’s made in a controlled factory, which means less waste and they can actually incorporate recycled bits too. Plus, its thermal mass, that just means it absorbs and releases heat slowly, which helps keep your home at a nice temperature, without blasting the heating or air conditioning constantly.

• 2. Recycled Steel: Steel is amazing stuff. It’s ridiculously strong, very durable and the best bit, it’s recyclable. Using recycled steel means you’re not needing as much new steel to be made, which requires a lot of energy.

• 3. Hempcrete: Now, this is a cool one. It’s essentially hemp fibers mixed with a lime-based binder. It’s super lightweight, an excellent insulator, and even fire-resistant. And the real win? Hemp is a fast-growing, renewable resource. It actually sucks up CO2 as it grows, making hempcrete a carbon-negative building choice. I mean, how cool is that?

• 4. Mycelium: Right, stick with me. Mycelium, the root structure of fungi, is another one that’s gaining ground. You combine it with agricultural waste, and you can mould it into pretty much anything – insulation, wall panels, even furniture. It’s biodegradable too, and has great thermal and acoustic properties. Who knew mushrooms could do that?

• 5. Bamboo: We all know bamboo, right? But it’s not just for pandas and garden fencing, it’s also seriously strong and flexible. This means you can use it for flooring, beams, even structural parts of the building. Plus, it grows ridiculously fast, which makes it a really sustainable option. You’re never going to run out of it.

• 6. Insulating Concrete Forms (ICFs): Think of ICFs as interlocking foam blocks that you fill with concrete, this gives you super insulation, which cuts down on heat loss through the walls. They also give really good soundproofing, and they’re resistant to fire and pests. All in all, they’re a win.

• 7. Structural Insulated Panels (SIPs): These panels are made with an insulating foam core, sandwiched between two structural layers. They give amazing insulation and airtightness, which is great for saving energy. Plus, they’re prefabricated, which really speeds up the whole building process. I was speaking to a contractor recently who built a small home with SIPs in record time.

• 8. Low-E Windows: You probably have seen these. Low-E, or low-emissivity, windows have a special coating that reflects infrared radiation. They help keep the heat out in the summer and keep it in during the winter, which again, saves energy. My own windows are low-E, and I can certainly feel the difference on those hot summer days.

• 9. Cool Roofing Materials: Ever felt how hot your roof gets in the summer? Cool roofs are designed to reflect more sunlight and absorb less heat. This means your home stays cooler, so you can dial back the air-con. You can get reflective coatings, shingles, and tiles for this. There is a real noticeable difference.

• 10. Recycled or Reclaimed Wood: Instead of chopping down new trees, why not use wood from old buildings or structures? It adds character and a unique look, while minimizing your environmental impact. Plus, reclaimed wood tends to have this beautiful, weathered feel to it, giving any space a touch of warmth and history, and the best thing its all been used already.

Using these materials in your new home isn’t just about going green; it’s about creating a comfortable and cost-effective space to live in. That being said, don’t forget about your local climate, budget and personal taste. Don’t be afraid to consult a green building pro. They can really help you make the right choices for your dream home. Ultimately, it is your home, so make sure you feel happy and at peace living in it, a home that is both sustainable and beautiful?
