Building a sustainable home doesn’t have to have expensive bells and whistles. With a few key design principals, a sustainable home can be built at little to no additional costs!
Chef and restaurateur Dan Zeidan and his partner Vicky Kordatou embarked on a colossal and experimental project to build their dream sustainable home. The home is located on a 10 acre property at Kinglake, an hour away from Melbourne. This is an area familiar to extreme climate conditions; it was one of the worst hit by the Black Saturday bushfires in 2009.
With the help of eco designer Joost Bakker, Dan and Vicky achieved a zero waste and flame zone rated home made from recycled and recyclable nontoxic materials including straw bale walls for insulation, fire proof magnesium oxide board as cladding and an exterior made up of a metal cage filled with crushed brick for a unique finish. For Dan and Vicky, aesthetics were not the top priority; rather they wanted a home that was functional and coexisted with its environment. The outcome is a home that will withstand and endure the harsh elements of this site and most importantly a home that was designed and built with sustainability in mind.
A sustainable home must respond to the local climate and surrounding environment, remaining comfortable with minimal heating/cooling demands. Here are some simple ways to incorporate sustainability design principles in your home.
PASSIVE SOLAR DESIGN
Passive solar design uses the energy from the sun to heat, cool, and illuminate the home, resulting in low heating and cooling bills. There are three key elements:
1. Building Orientation
Choose a site or home with a good orientation for your climatic and regional conditions, this will maximise the site’s potential for passive heating and passive cooling. Good building orientation and appropriate room layout will bring warmth to living areas in winter and roof shade protection and cooling breezes in summer. In Australia, the ideal aspect is for main living areas to face north or north-east
2. Carefully designing the building envelope (roof, walls, windows and floors)
Careful consideration of window placement and size, glazing type (double or treated glazing), efficient heating and cooling systems, solar hot water, solar panels, green roofs, walls and facades, rainwater capture and greywater reuse can enhance the performance of your home. One aspect of the incorporation of ‘green’ is consideration of control of pests that are part and parcel of incorporating nature in a build.
3. Existing buildings can also be adapted or retrofitted to be more sustainable.
During a renovation, reorient rooms (where possible) for optimum solar design. Adding insulation to ceilings, walls and floors, and adding energy efficient lighting and water efficient fittings are also simple, effective ways to improve a home.
SUSTAINABLE BUILDING FEATURES
1. Green roofs, walls and facades
These features can reduce stormwater drainage and improve the thermal performance of a building by reducing heating and cooling. On a larger scale, it can help cool a city, create and preserve various habitats and promote ecological biodiversity which enhances our urban landscape and cleans the air.

2. High Performance windows – when building, window systems are one of the high cost ticket items and selecting the right solution for your home is key. There are many window configurations on the market, from using low-e coatings, selective transmission films, inert gas fills and thermal breaks to a combination of these for the right application. Energy efficient windows will make your home more comfortable while dramatically reducing your energy costs and helping to create a brighter, cleaner, healthier environment.
Finally to help you with your next sustainable project and research don’t forget to attend the Sustainable House Day and keep the Sustainable checklist handy for your reference.
3. Sustainability checklist for designing a new home or renovating a home
Locate rooms most used (kitchen, lounge and bedrooms) on the side of the house orientated to the North.
Locate rooms to take advantage of winter sun and cooling summer breezes.
Consider window size and placement to promote and enhance cross- ventilation to the south, east and west.
Thermal mass can be achieved by relocating utility areas through bathroom renovations and moving laundry areas to garages) on the south or west where possible, avoid locating sleeping rooms on the west.
Structures such as carports or sheds that will block northern sun should be minimised if located on the northern facade.
Overall landscape design with plant and the strategic placement of refuge collection areas should funnel cool breezes and block or filter harsh winds.
Vegetation should be pruned to avoid blocking out winter sun. Planting deciduous vegetation that allows winter sun to penetrate and provides shade during summer is a great option.
4. Sustainable House Day
Since 2001, Sustainable House Day (in collaboration with the Australian Solar Council) has given visitors a chance to inspect houses that have been designed, built or renovated with sustainability in mind. This year’s event will be held on Sunday 13 September from 10am to 4 pm. For more information and a list of participating homes near you, visit sustainablehouseday.com.

The technology available for residential homes in 2016 is simply extraordinary. Wise Group Home Security in a recent release predicts continuing strong growth in home automation solutions and predicts this global trend will continue globally for some years to come.
Consumers have only had the old type of alarm panel as their past home technology interface. Shortly, according to industry insiders, consumers are going to have solutions that will allow communication and interaction with their home on an extraordinary number of levels in real time.
A recent report by United States research house, Transparency Market Research, valued the global home automation market at US$4.4 billion in 2014 and predicted it would increase at a compound annual growth rate of 26.3 per cent until 2020, taking the market to over $US12 billion.
Transparency Market Research found trends boosting the market were automated solutions used for lighting, safety and security, HVAC (Heating, Ventilation, and Air-Conditioning), entertainment, energy management, as well as many others.
Mr Kyle Gray, Wise Group Solutions Business Manager said, “architects and engineers were now looking more closely at home automation options and although Home Alarm Monitoring has played a high priority in the past, more emphasis is being placed on such things as managing energy usage through heating and cooling applications. He went on to say, “with the advancements in technology, confidence in wireless digital solutions has grown significantly and we are also seeing a greater call for this type of home automation solution.”
The prolific number of new products coming to the market in the ‘affordable’ automation space clearly indicates that the home automation market is growing at a rapid pace and there’s no sign of it abating.
From what designers have hinted at having on the drawing board, the possibilities in home automation solutions are endless. These new applications will put the automation panel as being a key component to not only greater home security but also play a major roll in home energy savings from the time it is installed.
