Great Australian Dream Planned Estates May Not Be Built

Great Australian Dream Planned Estates May Not Be Built

Our Australian research shows that the design and construction of new homes in Australia can leave residents at risk from heatwaves. Local councils are unable to address this problem.

Our research focused on Jordan Springs, Penrith in Western Sydney. The estate might not be able to withstand future heatwaves. This could put residents at risk and make them more dependent on expensive air conditioning.

Already, Australia is experiencing heatwaves. The Intergovernmental Panel on Climate Change warned this month that heatwaves would become more intense, frequent, and prolonged.

Rising house prices in Australia’s largest cities are leading many to seek out more affordable housing options on the fringes of major cities. However, these estates could be unsustainable as heatwaves intensify without the intervention of local governments and councils.

Hot Temperatures Are Made Worse Australian

Jordan Springs, a planned housing estate that dates back to ten years, is located 7km from Penrith. The estate had 5,156 residents as of the 2016 Census. It is home to 1,819 residents, and the estate will grow to approximately 13,000 residents in 4,800 additional homes.

The Following Was The Result Of Our Research

Collecting secondary information about the region, such as climate forecasts and regional growth forecasts. Conducting interviews and surveys with residents, officials of government and councils, and scientists. Analyzing the physical heat exposure of the estate using aerial imagery and groundcover analyses.

Because there are no cooling breezes from the coast, the inland suburbs are much hotter than the ones on the coast. Penrith is 60km west Sydney’s central business area. Penrith has three times the number of days that Penrith sees above 30 than the CBD.

Jordan Springs complies with all building regulations. Individual homes also comply with the Building Sustainability Index (BASIX) of NSW. We found that the estate’s built environment is too hot and that it exposes residents to higher indoor temperatures. This highlights the need for better building design and planning regulations.

Our findings could be applicable to other planned estate developments in Australia and New South Wales. However, more research is required to confirm.

What We Found Australian

The estate has a minimum of 6m between homes and the nearest neighboring property. This prevents air flow and allows heat to build up during the day. This reduces the space available for vegetation.

The streets of the estate are wide, and the buildings are low. This allows for less shade and maximizes sunlight on roads, roofs and other hard surfaces.

Nearly 59% of Jordan Springs are heat-trapping hard surfaces such as asphalt and concrete. This is compared to 10% combined tree- and shrub cover. Lack of greenery can lead to heat accumulation.

Dark-coloured houses, roofs and the surrounding surfaces (such roads, walls, fences and fences), increase heat absorption. As an example, it has been shown that dark roofs are 20-30 degrees hotter than those with lighter colors (see the images below).

Last week, the NSW government recognized the dangers that dark roofs can pose in hot weather and announced that light-coloured roofs would be required in new homes in southwest Sydney.

We found that some Jordan Springs houses were poorly insulated, and even draughty. Many of these homes achieved a high BASIX star rating in terms of energy efficiency.

The Conversation asked Lend Lease for a response. A spokesperson for the company said that due to the technical nature the findings, the company could not provide an adequate response by the deadline.

A Persistent Australian Problem

The built environment can make it more dangerous for people to live in heatwaves. To beat the heat, many people turn on their air conditioners. This increases energy consumption and leads to higher electricity bills.

Hence, Why Is This Situation Still So Prevalent?

One councillor believes that developers are motivate by profit. He tells us:

The developers think only about themselves and their directors. I don’t believe the developer is eco friendly.

A Scientific Expert Australian Stated

People don’t want to build double bricks because it is too expensive. Instead, they want to move fast and make a profit.

Media reports have reported that private certifiers have signed off buildings that do not comply with planning guidelines in recent years. According to one local councillor, this could lead to homes that aren’t suitable for hot weather.

Even if they could enforce more stringent rules, councils risk losing developers’ interest and the associated financial benefits. Unsatisfied council officials stated that if one council had strict rules about heat and housing development, the other would not.

Developers are more likely than others to move there to build housing. It’s a delicate balance. We want growth and want to work with developers. But we also want to improve our current practices.

Many planned housing estates aren’t ready for the changing climate. Residents can take steps to ensure their estates and homes stay cool in hot weather.

Install heat-resistant features like blinds, shades, and awnings wherever possible to increase passive cooling. This will also reduce the dependence on air conditioners. Encourage communities to take part in estate-wide greening efforts by planting trees and shrubs in their gardens.

Developers and councils should make sure prospective residents are aware of the advantages of passive design, light-coloured materials and urban green spaces. This will help them make better decisions throughout the construction process https://107.152.46.170/togel-online/bandar/pelangi4d/.

However, it is ultimately up to state governments and developers to ensure that future and current housing are heat-resilient. While it important to build new homes and return profits, citizens living in warmer countries must be taken seriously.
