Green Roof Components and Functions

The video tutorial explains the various layers of a green roof, including vegetation, substrate, futuring, draining, root barrier, waterproof membrane, and thermal insulation. It discusses the types of plants suitable for green roofs, such as succulents, grasses, wildflowers, and aromatic herbs. The video also covers the importance of each layer in maintaining the health and functionality of a green roof, and provides guidance on selecting appropriate plants based on regional climate.

What is the primary function of the vegetation layer in a green roof?

• To drain excess water

• To supply oxygen and keep the roof fresh

• To act as a waterproof barrier

• To provide structural support

Which type of plant is known for its ability to conserve water, making it ideal for green roofs?

• Succulent plants

• Wildflowers

• Grasses

• Aromatic herbs

What should be considered when selecting plants for a green roof?

• The height of the plants

• The climate and region

• The flowering season

• The color of the plants

What is the role of the culture medium layer in a green roof?

• To feed the plants and keep the roof healthy

• To provide thermal insulation

• To act as a root barrier

• To provide structural support

What is the purpose of the futuring layer in a green roof?

• To keep the vegetation and substrate above the roof

• To act as a waterproof barrier

• To provide thermal insulation

• To drain excess water

Which layer is responsible for managing water retention and drainage in a green roof?

• Draining layer

• Root barrier

• Thermal insulation

• Vegetation layer

What is the function of the root barrier in a green roof?

• To provide thermal insulation

• To prevent roots from penetrating the roof

• To act as a waterproof membrane

• To support plant growth

Why is the waterproof membrane important in a green roof?

• It acts as a thermal insulator

• It enhances plant growth

• It prevents water from seeping below the roof layers

• It provides structural support

What is the role of thermal insulation in a green roof?

• To act as a transition between the green roof and the building

• To provide a waterproof barrier

• To drain excess water

• To support plant growth

Which layer acts as the transition between the green roof and the building structure?

• Root barrier

• Thermal insulation

• Draining layer

• Vegetation layer
