DESCs are real control towers for sites equipped by Dalkia, combining human intelligence and digital performance. Its analysts are in constant contact with our employees close to the facilities, for greater responsiveness and efficiency in their interventions. Numerous sensors (IoT connected objects) and meters are integrated into buildings, equipment and energy facilities. They transmit large amounts of data to DESC, which retrieves and analyzes them and acts in case of malfunction. DESC also studies consumption over time to propose improvement plans, if necessary
