What is embodied energy in building emissions?

Embodied energy refers to the total amount of energy required to produce, transport, and assemble building materials, which includes the energy consumed not just in the extraction of raw materials, but also during manufacturing and construction processes. This concept is crucial in understanding a building's overall environmental impact, as embodied energy accounts for a significant portion of the energy emissions associated with a building's lifecycle.

When we consider option C, it encapsulates this definition by indicating the energy consumed in materials and construction. This encompasses all the stages of energy use prior to the building's operation, thus making it a critical component in evaluating the sustainability and carbon footprint of a building project. Understanding embodied energy is essential for architects, planners, and builders who aim to minimize environmental impacts and enhance energy efficiency throughout the lifespan of a building.
