Top 5 Sustainable Building in Australia
As soon as you lose the sight of set rules, innovation is born.
Should buildings have a car parking area? Is an air conditioner a must? Do we have to demolish old, inefficient houses to build better ones?
These and many other components of a building design [link to Going Green: Major Components of a Sustainable Building] have been increasingly challenged to give birth to the highest standards of sustainability and livability.
If you are looking for a stroke of inspiration in your career, here are recognized green buildings in Australia to transform the way you think about architecture.
Unconventional at first sight, these design models mark a new path towards long-lasting, sustainable solutions — for the sake of people and the planet.
“Build what people need rather than what you think they might want”, states Jeremy McLeod, the founding director of Breathe Architecture. Hence the mantra of Nightingale 1 project: “build less, give more”.
The award-winning development of The Commons by Breathe Architecture led to the Nightingale Housing Project to give the successful and sustainable practice of The Commons a much wider implication.
Nightingale 1 uses no gas – it’s 100% fossil fuel free and carbon neutral in its operation.
The solar system (combined with metering system and electrical reticulation) provides each resident with 100% green power at wholesale rates.
These are acknowledged features. The building received a rating of whooping 8.2 stars by NatHERS – a Nationwide House Energy Rating Scheme that celebrates the thermal performance and energy efficiency of a building.
Water efficiency is another key aspect of this project. Rainwater harvesting tanks are used for irrigation and common-area toilets.
When you swim with the current, most probably you construct a building where people rarely socialize with their neighbours and your major concern is to make the highest possible profit.
With bike storage, no individual laundry, and a shared veggie rooftop garden Nightingale 1 is not only environmentally-friendly, but it’s also designed to foster community spirit and be affordable.
Interestingly, Jeremy’s father took him to his first protest when he was only eight. Protesters were demanding affordable housing. Four decades later, Jeremy is at the forefront of the cause for sustainable, socially inclusive dwellings at cost.
In fact, the concept behind this building incorporates the principles of the Baugruppen movement from Germany, where people share resources and build a community while, at the same time, maintaining their privacy.
Glenn Murcutt has no team. At the age of 83, he still goes alone in architecture to create houses that harmonize with nature and have minimal impact on the environment.
Any construction project Murcutt commits to highlights his core value: “touch the earth lightly”. In case of Donaldson House, it took nearly ten years to live up to this mantra and bring the house to fruition.
A tree trunk extends through a gap in the roof, and large windows of the house frame the beautiful views of the surrounding nature. But that’s only the tip of the “green” iceberg.
Water storage tanks serve the bathrooms and laundry and are also meant to be used in the event of fire (the house is located in a high fire-risk area). Hot water is solar generated.
Solar panels generate the needed electricity which is significantly reduced owing to carefully placed windows and smart use of the sunlight. In addition, window louvres help to shade the house during the summer heat thus eliminating the need for air conditioning.
Murcutt has no grand and showy buildings in his portfolio but he is the only Australian architect who won the prestigious Pritzker Architecture Prize which is often called the Nobel Prize in architecture.
Rammed earth walls combined with morphed roof make up a building that has come to meet the highest standards of passive design and demonstrate excellent thermal performance. The building received NatHERS 7.6 star rating to celebrate the energy efficiency of the design.
There is no gas in the house that ensures net positive CO2 emissions.
The designers and builders brought in energy efficient lighting (LEDs) and appliances. PV panels generate electricity from sun making the home net-positive in energy as well.
A greenery-covered wall welcomes you in the entrance lobby as you walk into the building. And that’s only the entrance. You can’t fail to notice (and admire) the vast amount of plants spreading joy and extra oxygen in the space.
What’s more, 25 King is recyclable at end of its life.
The type of wood is sourced from spruce trees from sustainably grown forests and are known as one of the fastest growing species.
Especially for commercial buildings, transport connectivity is a major point. The building is located nearby train hubs and bus lines allowing workers to reduce their carbon footprint by using public transport every day.
“To innovate is to imitate” is what comes to your mind as you dive deep into the concept of this building’s design.
Termites, more precisely the “buildings” that termites construct, inspired the green concept behind Council House 2.
Mick Pearce is a Zimbabwean architect, and he brought this concept from African savannas dotted by termite mounds. CH2 has an older “brother” – the Eastgate Centre – a shopping centre and office block in central Harare, Zimbabwe. It was probably the first building in the world to use ventilation and natural cooling to a high level of sophistication.
Let’s look inside a termite mound to find out how these creatures manage to ensure optimal temperature inside their nest.
As the air enters the mound from beneath, it cools down while the hot air escapes through the “chimneys” and the “roof” — thus controlling the temperature in the mound.
Called biomimicry, this technique breathes life into a building. The facade of the building “understands” the outdoor conditions by opening and closing at night and responding to the angle of the sun during the daytime.
Used by the City of Melbourne Council, CH2 became the first office building in Australia to be awarded a maximum Six Green Star rating by the Green Building Council of Australia.
The building satisfies the 60% of its hot water requirements with the help of 23 solar panels and has wind turbines on the roof to generate additional electricity. Gas-fired cogeneration plants supply 30% of the building’s electricity and help to reduce carbon emissions.
After three steps of filtration, the sewage water is used for toilet flushing and air conditioning. Add to this a rooftop garden and indoor plants (one plant per person) and you have a flagship building for sustainability.
Your building project does not have to be grandiose to be effective.
If you construct a space that
serves its occupants needs for long, long years to come,
is in harmony with nature and its surrounding,
pays tribute to the existing heritage,
boosts occupants’ health and well-being,
challenges rules to push the boundaries of existing practices, then you can stand side by side the architects and builders who are not merely sought-after professionals but also aspiring leaders in their field.
For such an ambitious career path you need solid knowledge background, skills, and hands-on experience.
