Energy efficiency helps to mitigate CO2 emissions and at the same time increase the security of energy supply. This is why energy efficiency is a key priority of the EU energy policy and of the latest flagship initiative, the Energy Union. At the COP 21 meeting in Paris in 2015, countries have agreed to mitigate the impact of climate change by limiting the global temperature increase to well below 2 °C above to the pre-industrial levels and possibly stabilizing the temperature increase to 1.5 °C. Energy efficiency is a key mitigation option and it is recognized as the clean- est, quickest, and cheapest energy source. Not only this, but energy efficiency brings several additional benefits for end users, such as lower energy costs, more reliable equipment, higher production qual- ity, and reduced emissions. However, in some sectors such as the industrial sector, there are still a lot of bar- riers against investments in energy efficiency, particularly in small and medium Enterprises. Recent European legislation under the Eco-design and Energy Efficiency Directives is trying to remove these barriers and foster investments in energy efficiency; this is complemented by innovative financing for energy effi- ciency, the provision of energy services by ESCOs, and national programmes. Similar policy initiatives are also implemented in other countries around the world: Japan, USA, China, India, Australia, and Brazil. At the same, time progress in motor technologies as well as in drives and end-use equipment offers a very high level of efficiency, for example, IE 4 class motors now available on the market. EEMODS is the only international conference dedicated to energy efficiency in motor-driven systems. EEMODS began in 1996 in Lisbon, the last edition was orga- nized in Rome in 2017, and in 2019, the 11th edition was hosted in Tokyo, Japan. The conference is equally balanced between highly scientific and technical pre- sentations on innovative motor systems component designs and test methods to achieve a high level of efficiency and more policy-oriented presentations dedicated v vi Introduction to how to diffuse efficient motor systems solutions and technologies in existing industrial plants. The conference topics on the technology side cover motors and fluid applications (pumps, fans, and compressors), while on the policy side they cover both regulation for equipment and more horizontal policies such as energy audits and energy management systems. As with previous conferences in this series, EEMODS’19 provided a scientific forum to discuss and debate the latest developments in the impacts of electrical motor systems on energy and the environment, energy efficiency policies and pro- grammes adopted and planned, standards (including ISO 50.001), and the technical and commercial advances made in the dissemination and penetration of energy- efficient motor systems. Topics covered include: technologies, research, and inno- vation in the areas of electric motors from life cycle costing to 3D printing to artificial intelligence/machine learning-based monitoring systems; emerging motor technologies; power electronics and drives; pump systems, including life cycle cost- ing, energy efficiency improvements, maintenance, and operation for industrial, water supply and treatment, building, and irrigation pumps; compressed air sys- tems; fans/exhaust systems; refrigeration systems maintenance and operation; mechanical power transmission; motors in household appliances and HVAC (resi- dential and commercial); motors and drives for transport applications including policies, programmes, regulation, and international standards; industrial manage- ment policies and standards; motor system audit and verification; policies, pro- grammes, and financing: analysis of motor system energy use and greenhouse gas emissions for motor systems, for e-vehicles, and related charging infrastructure; harmonization of global motor efficiency test standards; evaluation of utility pro- grammes for improving energy efficiency in motor systems; and policy implemen- tation, market surveillance, and enforcement mechanisms, including case studies. The conference is very international by nature and aims to attract high-quality and innovative contributions from all corners of the globe, while the papers facilitate the development of new technologies, policies, and strategies to increase energy efficiency.
