Consumption of resources such as electricity, water and gas, is monitored for consecutive periods of time e.g. 12 hours or 24 hours, segmented into smaller subdivisions e.g. 20 minutes. Expected usage of the resources during each segment is input or calculated and compared with the actual usage in real time to provide a consumption indicator. A user interface is provided to display the consumption indicator for each segment of time. The user interface (24, Figure 1) may be connected to the monitoring system by transceivers (18, 20, Figure 1). The user interface may be a clock dial having bar indicators 30 each representing a 20 minute time segment. Each block 30 may have three LEDs in red, orange and green to provide a traffic light output, green indicating efficient resource usage in line with expected levels, orange signifying slightly higher usage and red indicating very high and uneconomic resource usage. A single combined output for use of electricity, gas and water may be provided or a single resource may be independently displayed. Accurate and relevant indication of resource usage can be displayed at any given time. |
