UPDATED 1 Sept: The EI library in London is temporarily closed to the public, as a precautionary measure in light of the ongoing COVID-19 situation. The Knowledge Service will still be answering email queries via email , or via live chats during working hours (09:15-17:00 GMT). Our e-library is always open for members here: eLibrary , for full-text access to over 200 e-books and millions of articles. Thank you for your patience.
New Energy World
New Energy World embraces the whole energy industry as it connects and converges to address the decarbonisation challenge. It covers progress being made across the industry, from the dynamics under way to reduce emissions in oil and gas, through improvements to the efficiency of energy conversion and use, to cutting-edge initiatives in renewable and low carbon technologies.
Save it: Why tackling energy efficiency in European buildings is a priority

Faced with escalating climate change challenges, enhancing energy efficiency in buildings is a priority. Buildings in the European Union account for 43% of final energy consumption and present a major opportunity to reduce emissions and conserve energy resources. Charlie Bush reports.
Buildings account for the largest share of energy consumption in most European countries. For example, buildings in the UK are responsible for 41% of energy consumption and 24% of energy-related emissions, according to the International Energy Agency (IEA). Similar patterns can be seen across the continent, underscoring the importance of energy-efficient buildings in reducing the overall carbon footprint.
Improving the energy efficiency of buildings requires a holistic approach, from construction and operation to demolition. The operational phase is particularly critical, as heating, ventilation and air conditioning (HVAC) systems are among the leading sources of greenhouse gas emissions. Not only do HVAC systems require significant energy to operate, but they can also cause environmental harm through refrigerant leaks. As in many areas of the energy transition, electrification is key.
Are homes becoming more efficient?
Efforts to curb energy use in European buildings have begun to yield results. Between 2000 and 2021, final energy consumption in the residential sector decreased by 9.3%, despite an increase in household numbers and the size of homes, according to European Commission figures. Improved insulation, energy-efficient heating systems and stringent efficiency standards have contributed to these positive developments.
