Embodied Energy
Embodied energy can be broken down into extraction, production, transportation and construction. Each wall assembly has different values. Applying these values from a wood-frame home and a net-zero green home to the overall energy efficiency of the building. The material with the least amount of embodied energy is wood, if it is from sustainably managed forests, but how much does that make up for the less efficient home. Since these homes will be in Kamloops, instead of a larger city, transport for some materials will make bigger difference than others. There are so many different types of materials that go into a home, therefore, I will only compare the exterior wall assembly of the two.

I wonder how much the embodied energy of the concrete will be reduced by the fact that we have a manufacturing plant just down the road?
ReplyDeleteThe biggest part of embodied energy comes from the production of the materials, but because the plant is nearby it will be interesting to see how much the transportation will offset the overall energy compared to that of a material that is further away.
