Eco-design and LCA

- Integrate an eco-design approach into the design of energy systems;

- Identify the steps in the Life Cycle Assessment methodology;

- Be able to analyze and critique a life cycle assessment that has already been carried out;

Know how to apply the life cycle assessment method to the study of an energy system.

Introduction: from life cycle assessment to LCA, ISO 14040 standards

- General principle of LCA

- Presentation of the four stages of LCA:

1-Definition of system objectives :

Purpose and scope of the study ;

Product or system function;

Functional unit and reference flows;

Process tree ;

Application examples;

2- Emissions inventories and extractions

Inventory database (e.g. EcoInvent...)

Example of extractions and emissions inventory (alumina production...)

Extraction and emissions inventory calculation method

Energy balance and CO2 balance

3- Environmental impact analysis

Method for interpreting inventory data

Intermediate characterization: calculation of the intermediate impact score

Damage characterization: calculation of damage characterization score

4- Interpretation

• LCA methodology: iterative approach (preliminary assessment or screening, detailed analysis), manual calculations, summary presentation of existing calculation software.

Program and content of the Design Office :
