Retrofitting Existing Buildings To Enhance Energy Efficiency And Reduce Carbon Emissions

Abstract

Retrofitting existing buildings to enhance energy efficiency and reduce carbon emissions is essential to meet the ambitious decarbonization targets for 2030 and 2050. Despite its importance, retrofitting faces several barriers, including substantial upfront costs, uncertainty of returns on investment, split incentives between owners and occupants, and a lack of adequate decision-support tools. Continuous improvement of retrofit analysis methodologies and tools, informed by feedback from active pilot projects, is necessary to systematically overcome these barriers.
