6.1.2.2. Techniques for Reduction of Green House Gas emissions

Try these first

1. 1.

   What percentage of CO2 emissions does the construction sector contribute?

   Hint

   Recall the main contributors as mentioned in the lecture.

2. 2.

   Name one carbon sequestering material.

   Hint

   Think of materials that can absorb carbon.

3. 3.

   What is the main focus of techniques aimed at reducing GHG emissions in construction?

   • Increasing waste
   • Choosing sustainable materials
   • Ignoring environmental impacts

   Hint

   Think about the purpose of these techniques.

4. 4.

   True or False: Renovating existing buildings can save between 50-75% of embodied carbon emissions.

   • True
   • False

   Hint

   Consider the benefits of reusing existing structures.

5. 5.

   Evaluate the impact of using a carbon-intensive material in a construction project versus its sustainable alternative.

   Hint

   Think about long-term implications for both environment and cost.

6. 6.

   Propose a construction project that maximizes both structural efficiency and waste minimization, detailing specific materials and techniques to utilize.

   Hint

   Consider real-world examples and successful techniques as part of your solution.
