摘要：This study evaluated the energy-saving effects of electricity consumption monitoring and energy-saving campaigns in Shinchi Town, Fukushima, Japan, where a community energy management system was introduced as part of recovery efforts after the Great East Japan Earthquake of 2011. First, a longitudinal evaluation through all six energy-saving campaigns conducted since 2014 illustrates that the first campaign showed the highest energy-saving effect, indicating the energy-saving potential brought by visualization of one’s own energy consumption by home energy management systems (HEMS). Declining trends in energysaving were observed over time. In addition, the correlations between the effects of energy-saving campaigns and trends in longer-term electricity use were noted to be minimal, indicating that the effects of energy-saving campaigns did not continue beyond the campaign period. It appears, however, that electricity consumption rates were restrained during each campaign implementation period. The fact that repeated appeals for energy savings were met with responses by the study target each time provides good prospects for demand-response processes that incorporate consideration of renewable energy usage.
