Abstract: A new technique was developed to non-intrusively monitor the use of individual gas appliances in homes.It relied on a very sensitive master gas meter equipped with a pulse meter, data logger, and software.The procedure involves two steps: decomposition and identification of the end uses.The technique is about 95% accurate but the algorithms can still be confused by some relatively common situations.Further improvements in the software are expected to improve accuracy.The procedure was applied to over 600 homes in Tokyo, Japan.The aggregate data allow more accurate estimates of energy consumption by the major residential gas appliances in addition to their hourly load profiles.Key factors affecting energy demand by each gas appliance were obtained by combining the energy and demographic data.These data are essential for more accurate forecasting of gas consumption, system sizing, and other marketing activities.The system will not necessarily be as successful in America due to the presence of pilot lights, more appliances per household, and variable-rate gas appliances.Nevertheless, the approach appears promising because it is economical and accurate.
