4. What does the term 'passive heating' refer to?

Heating a building without using any additional energy inputs

Using renewable energy sources for heating

Using active heating systems

Generating heat through human activities

Passive heating refers to heating a building without using any energy. It involves utilizing natural factors such as sunlight, insulation, and building orientation to capture and utilize heat efficiently, reducing the need for active heating systems.

Explanation

Passive heating refers to heating a building without using any energy. It involves utilizing natural factors such as sunlight, insulation, and building orientation to capture and utilize heat efficiently, reducing the need for active heating systems.

5. Which of the following is the primary purpose of insulating a building?

To keep the building warm in the winter

To keep the building cool in the summer

To enhance the aesthetic appeal of the building

To make the building soundproof

The primary purpose of insulating a building is to keep it warm in the winter. Insulation helps to prevent heat loss, ensuring that the indoor temperature remains comfortable even when it is cold outside.

Explanation

The primary purpose of insulating a building is to keep it warm in the winter. Insulation helps to prevent heat loss, ensuring that the indoor temperature remains comfortable even when it is cold outside.

Explanation

The purpose of weatherstripping is to prevent air leaks in buildings. It involves sealing openings such as doors and windows to prevent drafts, thereby enhancing insulation and energy efficiency.

9. Which type of insulation material is highly resistant to fire?

Cellulose

Polyurethane foam

Rockwool

Expanded polystyrene

Rockwool is an insulation material that is highly resistant to fire. It is made from volcanic rock or basalt and has excellent fire-resistant properties, making it a preferred choice in areas where fire safety is a concern.

Explanation

Rockwool is an insulation material that is highly resistant to fire. It is made from volcanic rock or basalt and has excellent fire-resistant properties, making it a preferred choice in areas where fire safety is a concern.

10. What is the purpose of thermal bridging in a building?

To increase overall heat transfer

To enhance structural integrity

To minimize energy loss

To improve ventilation

The purpose of thermal bridging in a building is to increase overall heat transfer. Thermal bridges occur when materials with high thermal conductivity (e.g., metal) create a pathway for heat to bypass insulation, leading to increased energy loss and reduced insulation effectiveness.

Explanation

The purpose of thermal bridging in a building is to increase overall heat transfer. Thermal bridges occur when materials with high thermal conductivity (e.g., metal) create a pathway for heat to bypass insulation, leading to increased energy loss and reduced insulation effectiveness.
