This document discusses a pilot project in Barcelona that aims to improve energy efficiency in buildings and intelligent urban lighting. It involves integrating a real-time data processing platform into data concentrators to acquire, process, and distribute energy data in real-time from buildings and street lights. This will enable real-time energy monitoring, analysis of consumption trends, and detection of inefficiencies. The project will deploy the system in phases, starting with a laboratory test and basic monitoring, then expanding to more advanced energy efficiency features and integrating data from additional sources and domains.
