Energy poverty, or fuel poverty, is often defined as a situation where low-income households are not able to adequately provide basic energy services in their homes and for their transport at affordable cost. A widely used criterion is to consider a household in fuel poverty when it spends more than 10% of its income on energy. But there is no consensus on a unique and explicit definition of the phenomenon as it is complex and has different causes and effects (temperature feelings, restriction behaviour…).

The buildings and construction sector accounted for 36% of final energy use and 39% of energy and process-related carbon dioxide (CO2) emissions in 2018, 11% of which resulted from manufacturing building materials and products such as steel, cement and glass. This year’s Global Status Report provides an update on drivers of CO2 emissions and energy demand globally since 2017, along with examples of policies, technologies and investments that support low-carbon building stocks.

Having reliable data and indicators on how energy is used is key to informing and monitoring the effectiveness of energy efficiency policies. Highlighting the importance of such data, the IEA has updated its Energy Efficiency Indicators database with annual data from 2000 to 2016, with expanded geographical coverage and an interactive visualization tool that better shows country-specific final energy consumption patterns across all end uses.

Numerous studies and surveys indicate that typically-installed HVAC equipment operate inefficiently and waste considerable energy due to varied installation errors (faults) such as improper refrigerant charge, incorrect airflow, oversized equipment, and leaky ducts. This article summarises the results of a large United States (U.S.) experimental/analytical study of the impact that different faults have on the performance of an air-source, single-speed heat pump (ASHP) in a typical U.S. single-family house.

This slide presentation describes the main results of a study operated by the National Institute of Standards and Technology (NIST) in the USA, to understand the impact of commissioning common faults on the energy consumption of an air-to-air heat pump installed in a single-family house.

The Energy Efficiency Indicators database contains annual data from 2000 to 2015, covering end use energy consumption for 8 energy products, end use energy efficiency indicators, and carbon intensity indicators for 4 sectors (residential, services, industry and transport) for the IEA member countries. The indicators are computed by using key sectorial activity data, for example, passenger kilometre energy intensity by mode/vehicle type (MJ/pkm).

This statistical report by the International Energy Agency (IEA), is designed to help understand what drives final energy use in IEA member countries in order to improve and track national energy efficiency policies. It is the second edition of a comprehensive selection of data that the IEA has been collecting each year, after its member states recognised in 2009 the need to better monitor energy efficiency policies. The report includes country-specific analysis of end uses across the largest sectors – residential, services, industry and transport. It answers questions such as:

Smart-Up is an EU funded project that will encourage vulnerable customers in those Member States that have embarked on the roll-out of Smart Meters to actively use their Smart Meters and In-House Displays to achieve energy savings.
Previous studies have shown that Smart Meters do not lead to energy savings in the residential sector unless households actively use them and modify their energy-use behaviour. This project will fill the gap, as well as raise awareness on demand response services.
