  1. Sustainability What we need to take into consideration for future cities

  2. Ecological Sustainability • Means: a way of ensuring that the needs of today’s population can be met without affecting the needs of future generations.

  3. Local Agenda 21 (LA21) • Three conditions: • Renewable resources – e.g. Timber should not be used faster than it is grown • Non-renewable resources – e.g. Coal used only together with substitutes (renewable resources) • Wastes – e.g. Garbage on produced in amounts that can be processed or reused

  4. Ecological footprint (EF) • A measure of the quantity of resources used by each person and/or household to produce the energy, food and infrastructure consumed as part of daily life. • It also looks at the amount of waste produced in the air, water and soil. • 6.6 billion people on earth entitled to an EF of 1.7 hectares of productive land. • Australia has the 5th highest EF with and average EF of 7.81 hectares per person

  5. Carbon Footprint • Component of EF • Looks at the amount of greenhouse gases produced by humans. • Average Australian households produced 32 tonnes of carbon per year in 2008 – one of the largest footprints in the world • Resulted in: • Australia signing the Kyoto Protocol • Carbon tax

  6. Water Footprint • Measure the volume of water used by the community to produce goods and services needed. • World average = 1.24 million litres of water per person (1/2 an Olympic pool) • Australian average = 1.39 million litres of water per person • Resulted in water restrictions during droughts

  7. Sustainable City

  8. Australia’s Ecological footprint

  9. Amount of Land and water Required by Sydney

  10. Questions Raised • How can a city such as Sydney be made more sustainable? • How can we make our footprint smaller (resources closer)

  11. Questions • Wikispaces: stage5geo.wikispaces.com • Ecological Sustainability • Questions: 4 and 6 • Towards the ecocity • Question: 1 • Textbook p.320-321 • Questions: 1-5 • Go to “Ecological Sustainability” and calculate your ecological footprint using the link at the bottom of the page

  12. Location and Materials • Australia is a vast land and has a variety of different climates • The majority of Australians live on the east coast of Australia and in cities. • When planning future sustainable buildings we need to consider: • what materials are we using and where we are getting them from. • reusing materials and structures already present. • Where are the buildings going to be (easy access to transport, amenities etc)

  13. continued

  14. Task • As part of the Sydney 2030 project you have been asked to design a sustainable building in Pyrmont. In your assigned groups organise your roles and begin to design your sustainable building for the future. • Consider: • Issues that have been raised • Location of your building • What materials you will use • What sustainable features will your building have • Will it have more than one use • Use the case studies as points of reference

  15. Due • TBA (to be advised) • 5 min presentation • Remember to make it interesting • Marked on engagement and innovation • Peer assessed • Reporter presents (read through info beforehand), gofer runs presentation, writer writes up presentation, manager responsible for keeping everyone on track. All responsible for research

  16. Consider: • Materials: • Renewable resources: timber, bamboo, straw • If using concrete, sourced locally / recycled • Reclaimed materials such as: bricks, metal • Local materials (quarry) • Insulation – natural (wool, newspaper)/ thicker walls • Energy saving: • Aspect (north facing)/ daylighting (placement of windows) • Blinds/ shades/ awnings/ trees for summer • Solar panels • Wind turbines • Double glazing + natural ventilation

  17. Consider: • Employee satisfaction: • Roof-top garden/ double as a filtration system • Pleasant working spaces • Air quality • High quality products • Vista • Reducing environmental impact: • Reducing and recycling waste • Reusing water • Location: • Near water = breeze • Near roads = noise
