1 Thriving Neighbourhoods Transformational Sustainability David

2 Green Building Evolution Green building design has gained rapid acceptance globally. It has evolved from being part of small boutique facilities to being a key component of global corporate HQ’s and highly cost effective commercial office developments. Truly green development mixes high performance buildings (works above ground) with innovative infrastructure (works below ground). Green Precincts and Cities are the next step.

5 Performance Summary – Design ASHRAE 90.1 Modelling

6 Today The Realm of Uncertainty Changes in “the natural means of the site” Changes in cost Changes in technology Changes in regulation Changes in market perception Changes in scientific consensus Certainty of outcome Reduced certainty of outcome Almost no certainty of outcome

7 What opportunities exist on the Precinct Scale

8 Simple Adjustable Fun Healthy Well made Stable & Dependable No Batteries Safe Bright Colours Affordable

9 Understanding the Spatial Layers of a City  built environment – buildings, public spaces, amenities and services  urban infrastructure – transport, water, waste, energy and food  natural attributes – land, water and air

10 Cycles Energy Water NutrientLife Future

11 Carlton United Brewery – Fraser’s Broadway Central Park

12 Carlton United Brewery (Fraser’s Broadway) Location: Sydney Stage: Design / Construction Stage Commissioned by: Frasers Property Use: Commercial, Residential, Retail Details: Commercial ~120,000 m2, 1689 Apartments ~235,000 GFA of built 6 hectares ESD Considerations:  5 Star Precinct PILOT rating  Water neutral  Sewer mining  Possible carbon neutral  Precinct heating/cooling  Cogeneration  No upgrade to infrastructure

13 Amended Concept Plan Targets Key Sustainability Initiatives: Elton Consulting “To aim for a zero net carbon and zero net potable water development” “Frasers Broadway has expressed the intention to move beyond base line compliance and towards the stretch goal of zero net greenhouse emissions (CO 2 –eq) development for operational energy use of the base building.”

14 What is Carbon Neutrality? Your carbon status is the net balance of carbon dioxide produced and carbon dioxide absorbed / avoided / offset. Carbon neutral therefore means that any CO 2 produced by on-site operation is accounted for either internal or external to the site. There are 5 levels of carbon neutrality that could be targeted: Base Building Operational Tenant Operational Construction Energy Embodied Energy Option 1 Option 2 Option 3 Option 4 Option 5

23 Comparison of Technology

24 Incomparable carbon savings, high risk, high capital cost, long term payback Heat competes with the trigen plant, expensive, looks good Expensive, minimal output for multi storey buildings, looks good, helped building approval Minimal output in the city and on small scale Cost premium required but useful Carbon effective, risky, expensive Good carbon reduction, minimal risk, cost effective
