Achieving low carbon local energy communities in hot climates by exploiting networks synergies in multi energy systems

•Local energy community modeled as a network of multi energy systems.•Primary Energy Saving as a metric for designing low carbon energy communities.•Investigation of low carbon scenarios with 10% and 20% of primary energy savings.•Thermal storage & district cooling allow to shave the cooling peak power installed.•Trigeneration and district cooling are key technologies to achieve low carbon goals.
