5.1.3.2. Embodied Energy and Embodied Carbon

Try these first

1. 1.

   What does embodied energy refer to?

   Hint

   Think about all the energy used to make and transport a building material.

2. 2.

   How is embodied carbon defined?

   Hint

   Consider the emissions associated with producing a material.

3. 3.

   What is embodied energy?

   • Total energy used in construction
   • Total energy used throughout a material's lifecycle
   • Only the energy for demolition

   Hint

   Consider energy used before construction too.

4. 4.

   True or False: Low embodied energy materials always have lower operational energy needs.

   • True
   • False

   Hint

   Think about the context in which the materials are used.

5. 5.

   Calculate the total embodied energy of a hypothetical building made mainly of wooden beams and concrete columns. Assume the energy values are 200 GJ for wooden elements and 300 GJ for concrete per construction.

   Hint

   Don't forget to include both materials!

6. 6.

   Propose a design for a small building that minimizes both embodied energy and operational energy. Include material choices and design elements.

   Hint

   Look at maximizing available resources and minimizing waste.
