The most effective form of material conservation in building practices is reusing existing buildings. This approach not only preserves the embodied energy and resources already invested in constructing the original structure, but it also significantly reduces the amount of waste generated from demolition and the demand for new materials. By opting to refurbish or adapt an existing building, the need for additional construction is minimized, allowing for a more sustainable development practice that contributes positively to environmental conservation.

Conducting whole-building life cycle assessments, while valuable for understanding the overall impacts of a building's design and materials over time, does not directly conserve materials in the same manner as reusing a structure. Recycling degradation products can help support material reuse, but it does not match the conservation potential of repurposing entire buildings. Purchasing sustainably sourced materials is important for reducing the impact of new construction, but it does not address the conservation of materials that already exist. Thus, reusing existing buildings stands out as the most impactful strategy for material conservation in the context of sustainable building practices.
