Proceedings of the 12th International Conference on Energy Efficiency in Domestic Appliances and Lighting

This book contains peer-reviewed papers presented at the 12th International Conference on Energy Efficiency in Domestic Appliances and Lighting (EEDAL'24), held in Kitakyushu City, Japan from 7-9 October 2024. Energy efficiency helps to mitigate CO2 emissions and at the same time increases the security of energy supply. Energy efficiency is recognized as the cleanest, quickest and cheapest energy source. Not only this, but energy efficiency brings several additional benefits for society and end-users, such as lower energy costs, reduced local pollution, better outdoor and indoor air quality, etc. However, in some sectors, such as the residential sector, barriers to investments in energy efficiency remain. Legislation adopted in several jurisdictions (EU, Japan, USA, China, India, Australia, Brazil, etc.) helps in removing barriers and fosters investments in energy efficiency. These initiatives complement innovative financing schemes for energy efficiency, the provision of energy services by energy service companies and different types of information programs. At the same time, progress in appliance technologies and in solid state lighting offer high levels of efficiency. LED lighting is an example. As with previous conferences in this series, EEDAL’24 provided a unique forum to discuss and debate the latest developments in energy and environmental impact of households, including appliances, lighting, heating and cooling equipment, electronics, smart meters, consumer behavior, new technology developments, policies, and programs. In addition, EEDAL also addressed non-technical issues such as consumer behavior, energy access in developing countries, and demand response.

Paolo Bertoldi is a senior expert in sustainable energy, climate change, and energy efficiency policies at the European Commission. Some key areas of his expertise include energy service companies, market based instruments, energy and climate policy analysis, environmental leadership, and ICT energy consumption. Dr. Bertoldi holds a doctorate in electrical engineering from the University of Padova. He is also the Editor-in-Chief of Springer's Energy Efficiency journal. He has published over 100 papers in leading academic journals, such as Energy Economics, Energy Policy, Renewable and Sustainable Energy Reviews, Climate Policy, Energy, Energy and Buildings, Journal of Cleaner Production, Nature Climate, One Earth, etc. Weijun Gao is a tenured professor at the University of Kitakyushu, Japan and an academia professor at Qingdao University of Technology, China. His research interests include the science, engineering, management, and dissemination of city environment planning, distributed energy systems, recycling building materials, health and environmental impacts of energy generation, geographic information systems, and climate change, especially in urban areas. Ji Xuan is a Senior Researcher at the Jyukankyo Research Institute (JYURI), where she has been working for over 15 years. Her recent research focuses on the analysis and forecasting of energy consumption in the residential and commercial sectors towards 2050, the operation and management of the Zero Energy Houses (ZEH) Committee, and the support of government-led subsidy programs in Japan that promote energy-efficient renovations of existing homes and the adoption of high-efficiency water heating systems. She has extensive experience in analyzing and evaluating energy conservation policies and measures in major countries worldwide, contributing to policy recommendations from an international perspective. She holds a bachelors degree in architectural environmental engineering from the Jilin Institute of Architecture and Civil Engineering in China, and both a masters degree and a Ph.D. in the same fields from the University of Kitakyushu in Japan. In addition, she delivers special lectures at Waseda University in Japan on energy and the built environment.
