For MR Building Life-Cycle Impact Reduction, what is required for Option 3?

For MR Building Life-Cycle Impact Reduction, Option 3 specifically requires a project to achieve 95% reuse or salvage of existing building materials by surface area. This high percentage commitment emphasizes the importance of minimizing waste and making the most of existing resources during the renovation or construction process.

By targeting such a significant reuse percentage, the option encourages teams to carefully consider how they can repurpose materials, thereby reducing the overall environmental footprint of the new project. This approach aligns with sustainable building practices and helps to preserve valuable resources, reduce landfill waste, and lower the energy consumption associated with producing new materials.

In the context of the other options, the percentages outlined would represent either lower targets for material reuse or focus on different criteria, such as volume instead of surface area, which do not meet the stringent requirements set by Option 3. This highlights how achieving 95% reuse or salvage reflects a strong commitment to sustainable development principles in construction.
