The Ater of the Municipality of Rome has entrusted ATI CPL CONCORDIA with the management of the heating systems of its real estate assets. As is well known, in order to make available all the energy necessary to heat the buildings in which we live, large quantities of fuels are burned that cause the emission of greenhouse gases into the atmosphere. ATER’s need was to reduce emissions into the atmosphere and energy consumption and therefore, in recent years, it has decided to introduce the use of thermostatic valves and electronic cost allocators.
