Degree of SprawlTransportation as Percent of Expenditures

Sprawling Places Are More Expensive

How Much Time Have We Got?

Some future scenarios have petrol prices at up to $8/litre in Australia. Even modest scenarios foresee $2 a litre within a few years

Surveys by Budget Direct suggest 30% of motorists in Australian cities will stop using their car to commute if petrol reaches $1.75 a litre

Costs to government$86 million (or approximately $80,000 per block) – or the cost to provide power, water, sewerage, schools, hospitals and local government services for fringe developments. Road infrastructure is the most significant cost.

Cost to people$250 million in transport costs over 50 years – people in fringe developments drive more frequently and own more cars $ 4.23 million in health costs – people in fringe developments have higher risk of obesity related to lower levels of physical activity for people.

Cost to the planet4,400 tons of greenhouse gas is saved for 1,000 urban dwellings, which is roughly equal to the amount emitted from 200 homes – an estimated dollar value of approximately $19.32 million.

Climate Change Adaptation

The Biggest Problem?

Adaptation Strategies in response to Changing Climatic and Environmental Conditions

a) Risk minimisation which takes into account impacts associated with rising temperatures, changing rainfall patterns, rising sea levels and changing storm frequency, type and intensity.

b) Response to changes in land use/value and planning. c) Prepare communities to adapt to climate change

including: impacts of population increases (or changes) on infrastructure needs such as transportation, energy and waterbushfire intensity and frequency

Energy Efficiency a Key Differentiator in the Short Term (for holders of property assets)?

As a result of required investment in green and renewable electricity generation and new carbon pricing mechanisms, it is certain that electricity prices will rise.

It is certain that under any carbon pricing mechanism super energy efficient green buildings will not only have lower operating costs (by a much greater margin than available to-day due to the future rise in energy costs) but may also be able to economically benefit from either avoiding carbon tax or by trading available credits.

A key initiative raised at the Prime Minister’s 2020 summit was “ carbon neutrality for all new buildings constructed beyond 2020”.

But the problem is even bigger…

Availability?

What if we replaced all of the cars in Australia with EV’s?

We would have 3 times (300%) the current power generation capacity for the nation........

Not only more energy more resources too…

Consumption of Non-Renewable ResourcesWhat does this mean?

No More New Buildings?......Probably the “right” answer but this is just not practical

We must encourage the market to Refurbish and Reuse and if new buildings are required (and they will be required due to increasing population and growth demands in the short to medium term) we need them to be developed using a high proportion of renewable resources and to operate on zero waste principals including carbon neutrality.

Conclusions New Ways Needed – A Change in Direction

Sustainable Built Form and Land Use

• Fewer cars (less roads), more public transport…..pedestrian and cycling priorities

Sustainable Built Form and Land Use

• Fewer cars (less roads), more public transport…..pedestrian and cycling priorities

• Urban growth containment• Higher density residential development with 1st

class public transport access nearby (TOD’s)• Resource Efficient Housing (not just Energy)• Urban farming, local food supply• Biophilic cities
