New Scientist article New research from Australia shows that aluminium roofs are gaining momentum in cities worldwide, thanks to the emergence of cheaper materials and innovative manufacturing techniques.
The research has been published in the Journal of the American Society for Materials Science.
The authors believe aluminium roofs offer a new solution for making buildings more energy-efficient, as well as lowering the price of aluminium.
In the study, published in a recent issue of the journal, the researchers tested several different aluminium materials.
The most cost-effective material was aluminium powder.
Using this cheaper material, the team found aluminium roofs were 20 per cent cheaper than conventional steel roofs and 15 per cent less expensive than conventional aluminum foil.
The team also found aluminium roofing made up more than half of the costs of aluminium fabrication.
The cost of aluminium roof materials is now below 5 per cent of the cost of conventional steel roofing.
The researchers believe that aluminium roof designs could be a “game changer” for cities worldwide.
“The key is to take advantage of low cost materials and innovation,” said lead author Dr Jeroen De Bock, an associate professor at the University of Melbourne.
“In addition to a lower cost per square metre, it also reduces overall costs because the materials used are cheaper than existing materials and can be fabricated in a cheaper manner.”
The research was carried out by researchers from the University for Sustainable Cities, Australia’s largest city-based sustainable urban research agency.
In a statement, the Australian Sustainable Urban Research Agency said the study highlighted the need for “green building” and sustainable urban design.
“This research shows how the latest advances in materials science and engineering can make the biggest impact for cities,” it said.
The researchers said the most cost effective aluminium material was aluminum powder. “
These findings will also have significant economic implications for the city and for its residents.”
The researchers said the most cost effective aluminium material was aluminum powder.
The use of this cheaper aluminium material, which can be manufactured at low cost, has allowed the researchers to test several different types of aluminium, including aluminum powder, aluminium foil and aluminium powder composite.
“There are many advantages to using a cheaper material like aluminium powder and the results show this to be the most effective,” Dr De Bocks said.
The paper also said the research showed aluminium roofs could be “the next big technology” in cities.
“We found that aluminium was the most efficient material used for roofing, with aluminium roofs costing only 5 per per cent more than conventional metal roofs,” the researchers wrote.
“It also reduced the cost per sq m and the cost to manufacture and assemble aluminium roofs by 20 per per, 15 per and 10 per per per sq meters respectively.”
The cost savings from aluminium roofs also showed up in other areas of the research.
The study found that the cost savings for aluminium roof construction was greater than for other roofing materials, like glass and copper.
The aluminium powder, which is more expensive than glass, was also less expensive to produce than aluminium foil.
“Aluminium roof building is a significant technology that could make a huge difference for our city, especially for low-income neighbourhoods,” the study concluded.
The new study is the latest in a series of research studies on the benefits of aluminium roofs to cities.
A number of studies have found that in the US, the cost and emissions associated with using aluminium roofs in cities have been falling.
In China, aluminium roofs have been found to reduce CO2 emissions by up to 10 per cent compared with conventional roofs.
The US has the world’s highest proportion of people living in cities, and it is expected that the global number of people will continue to increase as urbanisation continues to accelerate worldwide.
However, as urban planning continues to change, new ways of building and using buildings are being introduced.
In Australia, aluminium roof manufacturing has been one of the main ways that the government has sought to help meet the country’s energy needs.
A $15 billion investment in aluminium roof production has been announced by the federal government.
The project will create more than 150,000 jobs and is estimated to increase the Australian economy by an extra $4 billion.
