Energies for Ecodistricts - 5EU5DH7

Goal(s)

For the “energy networks” section, students will be able to:
-Understand, analyze and size the production, storage and distribution of energy networks (heat, gas, electricity).

For the “system reliability” section, students will be able to
-develop models of system reliability, with increasing complexity
-evaluate and analyze a system's dependability performance
-take account of dependability requirements in the design and management of a system
-design a system to comply with dependability specifications
