Question 1

Landcare

Answer 1

A national movement that brought farmers and conservationists together to resolve environmental concerns. One of the largest volunteer movements where thousands of people and community groups work together to towards sustainable land use practices.

Question 2

What does landcare do

Answer 2

Landcare groups voluntarily coordinate their management efforts with surrounding land owners. The government contributes knowledge, expertise and some funding to assist in the combined efforts of Landcare members

Question 3

Landcare activities to sustain healthy outdoor environments include

Answer 3

• planting native trees, shrubs and grasses to create habitat for native animals to improve biodiversity
• working with landholders and farmers to care for soils to help prevent salinity and erosion
• making ‘bug hotels’ to encourage bees and insects to pollinate gardens.

Question 4

Ethical and Sustainable consumerism

Answer 4

Ethical consumerism is the practice of spending money in a way that aligns with your values, while sustainable consumerism is about doing more and better with less.

Question 5

Examples of ethical and sustainable consumerism

Answer 5

Buying local and seasonal produce, changing energy consumption patterns, buying second-hand products and switching to fair trade products

Question 6

Green home design

Answer 6

the practice of creating structures (such as homes, offices and factories) using processes and materials that are environmentally responsible and resource-efficient.

Question 7

Key principles of energy-efficient design

Answer 7

block orientation, building materials, efficient lights and appliances, insulation and ventilation

Question 8

Block orientation

Answer 8

When choosing a block for your home, make sure it will allow you to place the living areas where
you spend the most time on the north side of the house. This will take advantage of the winter sun,
keeping these rooms warm, light and bright. Avoid or minimise windows facing west or east and
make sure they are well shaded for summer.

Question 9

Landcare effectiveness at Phillip Island

Answer 9

Biodiversity conservation Replanting native trees and shrubs have contributed to the recovery of habitats for species like the little penguin and other native wildlife

Water management Fencing off waterways and establishing buffer zones have been effective in reducing runoff and improving the health of local water bodies.

Climate change Planting drought-resistant native species (banksia) and managing coastal environments to combat erosion

Question 10

Building materials

Answer 10

Does your builder:
Buy local materials to reduce carbon footprint.
Select materials that don’t have toxic elements and can be recycled and reused.
Source timber from sustainable plantations and buy local materials to reduce carbon footprint?
Examples of sustainable building materials include bamboo, stone, laminated timber, reclaimed wood and anything recycled.

Question 11

Solar panels

Answer 11

An energy-efficient design should have solar panels as it reduces the contribution to non renewable energy such as fossil fuel production, and produces sufficient amounts of energy at lower costs.

To support this, the Government is providing a 50% rebate to eligible househ

Question 12

Insulation

Answer 12

Insulating homes ceilings, walls and floors can save up to 45% of the cost of running your home. Adding as much insulation as possible while making sure it is installed correctly with no gaps and proper waterproofing is a sound investment for a home.

Question 13

Efficient lighting

Answer 13

Allows you to take advantage of natural light, helping to save money on the energy bills

Question 14

Water

Answer 14

Save water by considering water recycling systems and choosing water saving fittings and appliances. Grey water systems are mandatory in most new housing systems. Energy saving shower heads can also receive a rebate in some council areas.

Question 15

Window frames, glazing and shading

Answer 15

Window frames help to ensure that the insulation value provided by the windows and walls is not lost through the window frames. Window glazing helps to boost the insulating value of the windows by up to 30% compared to traditional windows to ensure that homes are able to stay cool in summer and warm in summer. Window shading helps to block IR heat emitted from the sun and reflect them away from the house.

Question 16

Zoning and efficient heating and cooling

Answer 16

Designing zones in your home will allow you to efficiently heat and efficiently cool rooms individually. Doors are a great way to zone areas of your home, for example, between corridors and bedrooms or living areas, it’s a good way to keep heat where you want it throughout the house whilst using minimal energy to do so.

Question 17

Ventilation

Answer 17

Both windows and exhaust fans can help control ventilation and maintain air quality and minimise air leakage.

Question 18

Energy efficient hot water

Answer 18

A solar hot water system might be more expensive to buy and install, but the running costs will be significantly lower. The Victorian Government is providing a rebate on solar hot water systems for eligible households.

Question 19

Energy efficient appliances

Answer 19

When choosing fridges, televisions, washing machines, dishwashers and so on, choose energy efficient appliances with the highest energy star ratings. This reduces excessive energy use and saves on energy costs.
