*Scope and objectives of use case*
*Scope*	Urban transformations set the opportunity for developments of energy infrastructures more respectful of the environment, within socially- and economically- accepted boundaries. In this context, the development of district multi-energy systems offer a wide range of benefits. The connection of locally dispersed sources and sinks of energy and the consequent balancing of loads and productions can lead to a better management of the energy flows: lower installed capacities, higher energy efficiencies, recovery of waste heat, better integration of local resources and more flexibility. The design of the local multi-energy infrastructure (selection of the energy carriers, sizing of the production and storage capacities etc.) and its operation (arbitrage of imports, local generation, exports and storage etc.) has a crucial impact on the final economical, environmental and social performances. This use case optimizes the design of local energy systems with a multi-objective approach (exergy, energy, environmental, economical etc.)
*Objective(s)*	[identify specific objectives] O1: Optimize joint local energy infrastructures
