The document discusses a pilot program in Camden Council, London to install individual heat meters in 1,500 properties in block housing developments. This allows residents to be charged based on their actual heat usage rather than a fixed fee. Some residents have reduced usage by over 30% and overall savings of £195,000 and 16,000 tons of CO2 emissions are estimated annually. Hildebrand Technology provided the software and hosting to analyze the thousands of meter readings collected every 6 seconds using IBM Informix TimeSeries database software.
