Key Takeaways
Test your understanding of lifecycle assessment principles
Your Progress
Section 5 of 5Lifecycle Thinking
Assess impacts across all phases - planning, construction, operation (50+ years), renovation, and end-of-life.
Embodied vs Operational
Embodied carbon (materials/construction) now represents 20-50% of total lifecycle emissions as operational efficiency improves.
Long-Term Projections
50-year energy modeling reveals that upfront efficiency investments achieve 8-15 year payback periods through reduced operational costs.
Circular Economy
Design for disassembly, material reuse, and adaptability can reduce embodied carbon by 50-70% while extending building lifespan.
Scenario-Based Assessment
Apply your lifecycle knowledge to real-world building decisions. Each scenario presents trade-offs between embodied carbon, operational performance, and circular design.
