3.9. Energy Efficiency in Construction and Operation

Try these first

1. 1.

   What is thermal mass?

   Hint

   Think about how a material can help maintain temperature in a building.

2. 2.

   Name a benefit of using recycled materials in concrete.

   Hint

   Consider environmental impacts.

3. 3.

   What is the main benefit of concrete's thermal mass?

   • Increases weight
   • Regulates indoor temperatures
   • Reduces strength

   Hint

   Think about how temperature management impacts energy use.

4. 4.

   True or False: The use of recycled materials in concrete can reduce its carbon footprint.

   • True
   • False

   Hint

   Consider the benefits of reusing materials.

5. 5.

   If you were to design a school building, how would you integrate concrete's thermal mass with passive solar design to achieve optimal energy efficiency?

   Hint

   Consider angles and positioning of walls and windows.

6. 6.

   Discuss the potential trade-offs when incorporating high amounts of recycled materials into concrete mixes.

   Hint

   Think about both short-term and long-term structural effects.
