BLArch Bachelor of Landscape Architecture Sustainable Design and Green Infrastructure 3

Question 1

The concept of 'carbon sequestration' in landscape design refers to:

Accepted Answer

The capture and long-term storage of atmospheric carbon dioxide by plants and soil

Answer

Burying carbon-based construction products underground

Answer

Burning carbon-based landscape waste materials

Answer

Removing all organic matter from site soils before planting

Question 2

Which hydrological parameter is commonly used to estimate stormwater runoff from a landscape site?

Accepted Answer

Runoff Curve Number (CN)

Answer

Floor Area Ratio (FAR)

Answer

Floor-to-Ceiling Height ratio

Answer

Lot Coverage Percentage

Question 3

Native plant species are preferred in sustainable landscape design primarily because they:

Accepted Answer

Are adapted to local climate and soils, requiring less water and supporting native wildlife

Answer

Are always less expensive to purchase than non-native nursery stock

Answer

Grow faster than non-native ornamental species

Answer

Always produce more colorful flowers than exotic cultivars

Question 4

What does 'life cycle assessment' (LCA) evaluate in sustainable materials selection?

Accepted Answer

The environmental impacts of a material from raw material extraction through end-of-life disposal

Answer

The expected service life of a landscape plant species in the local climate

Answer

The time required to complete a landscape construction project

Answer

The duration of a contractor's materials warranty

Question 5

Which of the following best describes 'adaptive management' in sustainable landscape practice?

Accepted Answer

A management approach that incorporates monitoring, evaluation, and strategy adjustment based on observed outcomes

Answer

Designing landscapes that never require any maintenance inputs

Answer

Using only plant species classified as adaptive to multiple climate zones

Answer

Adapting traditional historical garden styles to contemporary sites

Question 6

The 'triple bottom line' framework evaluates sustainable design projects based on:

Accepted Answer

Environmental performance, social equity, and economic viability

Answer

Cost, schedule, and construction quality

Answer

Form, function, and aesthetic quality

Answer

Safety, accessibility, and long-term maintenance requirements

Question 7

In sustainable landscape practice, what is the primary environmental advantage of using recycled or reclaimed materials?

Accepted Answer

They reduce demand for virgin resources and decrease embodied energy and carbon emissions

Answer

Recycled materials are always structurally superior to newly manufactured materials

Answer

Reclaimed materials always cost less than new materials on the market

Answer

They require significantly less maintenance over the life of the project
