How Do Materials Influence Energy Use, CO2 Emissions and Sustainability? Consider a proposed functional object or system. We need: 1. A preliminary design that achieves the function and sets necessary constraints 2. A statement of the engineering objectives for each component in the design 3. A methodology to calculate a figure of merit for each component 4. A figure of merit for the ecological implications (embodied energy, CO2 footprint, water consumption, …) for each candidate material 5. An optimization (tradeoff) method to select the best material 6. A method to estimate the life cycle environmental costs
Derive Materials Performance Indexies Example: Component subject to principle mechanical stress But the methodology works for any property (thermal, electrical,…)
