The Energy Efficiency Hub is a voluntary collaboration among 16 governments seeking to strengthen their effectiveness in deploying energy efficiency. Its secretariat is hosted by the IEA. The Hub recently published a report from one of its task groups, the Energy Efficiency in Buildings Task Group, entitled Deep Energy Retrofit Models: A Global Perspective. The report focuses on the experience of Argentina, Brazil, People’s Republic of China, the European Commission, Germany, Korea and Saudi Arabia. Insights from Belgium, Canada, France, Ireland and the United States are also included.
Retrofits range from single-measure improvements, such as insulation or heating system upgrades or window replacements, to more comprehensive building overhauls involving the entire envelope and system upgrades. This report explores a particular type of building retrofit—the deep energy retrofit—which aims to significantly reduce energy consumption and emissions while enhancing building energy performance. Deep retrofit is an essential tool to reaching building decarbonisation by 2050, and the recommendations in this report focus on enabling widespread deployment of deep retrofits. There is not one definition of deep retrofit as it is shaped by national context. This report provides a framework to inform policy makers, industry stakeholders and practitioners to implement deep energy retrofits more effectively, ultimately contributing to global decarbonisation goals.
