The Barcelona City Council manages about 2000 municipal buildings and as expected the energy expenditure is very high. Hence, the objective was to closely monitor and control how these buildings are consuming and, in some cases, producing energy. Specifically, the aim was o determine the degree of utilization of energy produced by solar thermal systems in multifamily buildings. The project consisted on controlling and monitoring 28 solar thermal systems. It was divided into three phases; a pilot phase to monitor 4 initial sites, a second phase where 16 more were added, and a third phase where the final 8 were included.

The Ascó City Council wanted to monitor and control all 16 municipal facilities it manages, as a means of improving energy efficiency. The project first phase objective is to monitor the energy consumption of the city hall building and to automate and control HVAC equipment distributed across various floors on the building.
