Embodied energy refers to the energy consumed during the production, manufacturing, and transportation of building materials and components. It has an important impact on the sustainability of zero-energy architecture as it affects the overall carbon footprint of the building.
If a zero-energy building utilizes materials with high embodied energy, it may offset the energy savings achieved through efficient design and renewable energy systems. For example, a building constructed with heavy concrete that requires large amounts of energy to produce and transport will have a higher carbon footprint than one made of lightweight timber or sourced locally. This is because the energy used to produce and transport the heavy concrete will consume more fossil fuels and emit more greenhouse gases.
Therefore, sustainable design strategies for zero-energy architecture should prioritize the use of low-embodied energy materials, such as recycled or salvaged materials, or those sourced from renewable sources. Additionally, reducing waste during construction and focusing on local sourcing will help minimize the carbon footprint of the building’s construction. Ultimately, considering embodied energy in the design and material selection of zero-energy architecture is crucial to achieving true sustainability.
