The use of proportion can vary significantly in embodied energy and carbon emissions of buildings, depending on various factors such as the materials and construction methods used, building design and layout, and the building's lifecycle.
In terms of embodied energy, the proportion of construction materials used can have a significant impact. For example, using materials with high embodied energy, such as concrete and steel, can result in a higher overall embodied energy for the building. Similarly, the proportion of recycled or low-embodied energy materials used can lower the building's overall embodied energy.
In terms of carbon emissions, the proportion of fossil fuels used in construction and operation can have a significant impact. Building design and layout can also influence the proportion of energy needed for heating, cooling, and lighting. Moreover, the proportion of renewable energy sources used (e.g., solar power), can lower the building's overall carbon emissions.
Overall, the use of proportion in embodied energy and carbon emissions of buildings is a complex issue influenced by many factors. Designers, builders, and building owners must carefully consider the materials and energy sources used and prioritize sustainability to minimize the environmental impact of buildings.
