Material selection determines 40\u201380% of a building’s embodied carbon<\/strong>, depending on project type, structural system, and lifecycle assumptions. Low-Impact Construction require optimizing materials through measurable environmental indicators instead of cost-only decision making. The following framework focuses on quantifiable parameters used by sustainable construction professionals.<\/p>\n\n\n\n

1. Prioritize Embodied Carbon Instead of Initial Material Cost<\/h2>\n\n\n\n

Embodied carbon represents greenhouse gas emissions generated during raw material extraction, manufacturing, transportation, installation, maintenance, and end-of-life processing. Since operational emissions continue to decline with energy-efficient buildings, embodied carbon has become a dominant sustainability metric.<\/p>\n\n\n\n
