Energy-saving measures

This study investigates the impact of lowering temperature setpoints on occupants' thermal comfort in office buildings, prompted by government initiatives in Europe, including the Netherlands, to reduce energy consumption. The research methodology involved a case study conducted in three office buildings in The Netherlands. Data on occupants' perception, motivation, clothing thermal insulation, activity level, discomfort, and thermal control options were collected through interviews conducted for thermal comfort surveys and building surveys.

Energy consumption by residential sector of 20 Japanese cities was modeled at the city-scale. In the model, households were classified into 228 categories based on the family and building type. We evaluated the effectiveness of energy conservation measures, such as improving energy efficiency of home appliances, improving heat insulation of buildings, changing preset temperature, and all family members watching TV together. In addition, we also discussed differences in energy saving effects between cities.
