Lochiel Park: Background

• 103 dwelling, world best practice sustainable housing development,

(75 houses + 23 apartments)

• Coincides with SA State Government vision for Sustainable Living,

• Total development area of 14.7Ha (4.2 dwellings, 10.5 open space).

• Sustainability (reduction) targets:

– 66% in energy use,

• Reduce Heating / Cooling,

• Reduce water heating,

• Use roof-top solar panels.

– 74% of GHG emissions.

• Evaluate performance with real-

time monitoring systems: water,

gas, electricity, rooftop solar etc.

Energy lessons from Lochiel Park

Demand aggregation reduces peak demand per household

Demand management can further reduce peak demand

Energy-efficient homes require less distribution infrastructure

PV and energy efficiency reduce demand

New demand tariffs are not good for everyone

Lessons for Bowden, Tonsley and beyond

Enable greater use of local and grid-based renewables:

• smart meters

• embedded networks

• shared PV

• shared hot water

• shared electrical energy storage

• demand aggregation

• demand management

• We are using the evidence base from Lochiel Park in Bowden, Tonsley

and beyond

• Disruptive Change can be achieved through strong Government

leadership and a new engagement process

• Long term Government/industry/research partnership can provide

substantial outcomes

• Substantial additional funding can be secured through action research

• We are ready to engage to make Adelaide the first carbon neutral

city
