The term “sustainability” gets thrown around a lot in the building design industry, but what does it actually mean? And what are the ramifications for the home owner?

What is a “Sustainable Home”?

Sustainable home design is mostly about common sense and whether you’re building or renovating, you may as well get it right from the beginning. A sustainable home should be energy efficient and cheaper to run. It should be durable and made from materials that aren’t going to harm you or the environment. It should take into consideration how your family might change in the coming years, and adapt accordingly. And waste during construction should be considered, for both cost and environmental impact.

Here are some things we consider when designing:

Passive Design

Another “buzz” term, a passively designed home makes the most of natural heating and cooling methods to ensure the home is comfortable and running costs are reduced. The main components of passive design are: orientation, spatial zoning, thermal mass, ventilation, insulation, shading and glazing. Taking these into consideration can make a huge difference in how your home performs year-round. Good orientation is most important, taking advantage of the sun’s heat in winter and shutting it out in summer. This alone can drastically reduce the need for heating and cooling.

More on … Heating and Cooling

Did you know that Australian homes are traditionally ‘leaky’ and that draughts can be responsible for up to 25 per cent of your heating and cooling costs? We take this into consideration with our design and building methods to ensure there are no expensive gaps sucking away your hard-earned dollars. Insulation is another important consideration – insulation acts as a barrier that prevents heat passing in and out of a house, keeping a home cooler in summer and maintaining heat in winter. Insulation isn’t just for the roof – you can also insulate your
walls and floor for maximum energy efficiency. Spatial zoning ensures that a home’s temperature stays consistent throughout and avoids
hot or cold pockets as a result of warm or cool air escaping.

Designing for your climate and site

Different sites present different challenges, but the aim should always be to minimise summer sun and maximise winter sun. Air movement and ventilation are two more important considerations with the aim of designing for effective cross-flow of air throughout the building.

Sustainable materials

All materials have an embodied energy – the energy used over their lifecycle, from processing and manufacturing through to product delivery. A poor choice of materials can diminish or cancel out the benefit of all your other sustainable living choices. Also, as previously mentioned, materials should be durable to avoid the cost (to your pocket and to the environment) of replacing them. We try to use sustainably sourced timbers, recycled or locally sourced materials, and low volatile organic compounds (VOC) finishes. Thermal mass is another consideration for materials – this is the material’s ability to absorb and release heat. Bricks and concrete most often give the best results.

Glazing

Windows and glazed doors can be a major leak of heat, in and out. How much glass your home has, and where those windows and doors are situated, can have a huge impact on this and is an important consideration at the planning stage. For a design featuring lots of glass, a popular choice with many, we would recommend double glazing to maintain the advantages passive design.

Designing for the long haul

Make sure your home is designed to last, with materials that are durable and reusable or recyclable. Also think ahead – will your family grow, shrink or stay stable? The aim is to design a home that not only meets your current needs, but can adapt to your changing needs without incurring too much cost.

Remain engaged

Once you have moved into your sustainable home, our advice is to think about how your home is working day to day – pull down blinds to block hot sun, open doors and windows to capture cool breezes. Remaining engaged with the design advantages of your home can help lessen the environmental impact and ensure your home performs as well as it should.

Would you like to walk through your new home months before the builders arrive? It might sound fanciful but it’s become the new reality for home builders. One that can save money and mistakes down the line.

Communicating ideas accurately can be an incredibly hard thing to do. And when those ideas involve an investment as significant as your new home, you want to know that both you and your designer are understanding each other.

We live in a visual age and we also have amazing technology at hand. These two factors have seen massive changes in the building design industry. At Etchells we’ve embraced this new way of working and believe that it’s of great benefit to our clients.

The days of a large, two dimensional, paper house plan (and your designer trying to talk you through what the various black lines represent) are all but gone. Mind you, we love our architectural drawings, and they’re still our starting point, but they can be tough for a client to understand, let alone to get a feel for what life in their new home will be like.

Just as we try to accurately create the home that’s in your heart and mind, we want you to thoroughly understand what we’re delivering. We do this by giving you accurate yet easily digestible information. Here are some of our strategies.

An early step we like to take with you is to have you set up a Pinterest board for your new home and start pinning! It’s amazing just how much this can get the ideas flowing and also accurately identify your preferences. Once you’re happy with your pin board we’ll ask you to share it with us. It’s that easy. It’s a great first step in the visual communication of your project – creating a mood board for your dream home. Don’t worry if you’re not familiar with Pinterest, we can introduce you to it. We promise you’ll be hooked before long …

We’ve found that these are one of the best visual tools available to convey the overall look of your new home. We create anywhere from six to 12 of these high quality, photo realistic, rendered illustrations of your build, from different angles, showing interiors and exterior. You basically get what looks like an expensive photoshoot of your home … before the foundations have been laid.

Integrated landscaping

We like to deliver a full service so we always include integrated landscaping in our renders. These are details that you needn’t go ahead with, but many of our clients do once they’ve seen it. It’s a great way of visualising your build as a finished home, settled into its surroundings, and a way to take advantage of Etchells’ design expertise in all aspects of your home.

Colour palette

We also create a palette of colours and wall finishes when producing your renders. These can include a range of cladding options as well as paint colours, taken from a library of paint manufacturers’ swatches. Again, it gives you an accurate indication of what your home can look like upon completion.

BIMx is a simple and intuitive interface with viewer applications for both Apple and Windows. You can even use it on your smart device. It basically delivers sophisticated 3D models in a form that’s easy for the layman to use and explore.

Our clients love this feature – an easy to use tool that means you can virtually ‘walk’ around your new home. You can even take measurements (maybe you’ve seen a sofa you love!) and if you’re technically inclined, the real-time cutaway function means you can view the construction details within the model.

Most clients find the 3D modelling is simply the best way to get a feel for their new home – the functionality and ‘liveability’ of the spaces within. It’s a really exciting step in the design process. It’s also the best way of insuring you’re absolutely happy with the layout. Changes can be very costly once construction commences, so it’s essential to have a thorough understanding of your design before building starts.
