3. The CEDSS Model 3 Community Energy Demand Social Simulator Households located in a street-network, making decisions about buying energy-using and energy-saving appliances and equipment. Households’ energy use, and expenditure on energy and energy-related equipment, is tracked over time. Data for runs of the model covering the period 2000-2010 is drawn from a range of publicly-available sources, and from the first (2010) GILDED survey. Runs covering the period 2010-2050 are in preparation.
