10. Sustainable Development and Land Subdivision Flashcards
Why build sustainable buildings? (3)
- Legislation - voluntary but minimum insulation and green requirements and Govt buildings > $9m need to be 5 star green
- Tenant requirement for top end rent
- Need to reduce carbon emissions (may become legislated)
How can carbon emissions be reduced through structure?
Hybrid of timber and steel rather than traditional steel and concrete
How is carbon emission calculated?
EDP rates * quantities
What percentage of GDP, jobs and raw materials are contributed/used by global building?
10% GDP
7% jobs
50% raw materials
What percentage of energy and waste is used by global building?
36% energy
40% waste
What percentage of global carbon emissions is contributed by the manufacture and installation of building materials?
37%
What is a green building?
A building asset that is environmentally responsible and resource efficient
What environmental progress has been made? (5)
- Sustainable protocols common
- Energy efficiency for CBD high rise common
- Tenant driven for high end rent
- Sustainability not a regulatory requirement
- Govt requires own leases to adopt green leases
What 4 categories are available for Green Star certification?
