The existing controls have been replaced by Siemens Desigo BEMs which already saves the energy up to 28% alone. Council staff can monitor alarms, temperature, operating hours and holiday periods. Parameters can be set for heating and hot water system with alarms coming into effect if limits are reached. This enables operator know where the energy waste occurs and action can be taken afterwards. Alarms are also raised if there are maintenance issues with equipment such as switched or pump so action can be taken before substantial impact occurs.
Another great benefit of the system, stated by Paul Colston who is a carbon-reduction officer in the council, is that it shows the savings achieved by capital investment improvements such as new doors and windows. The future improvement will be focused on installing systems in other types of building and controlling lighting.
