There is a growing interest in research dealing with energy performance gaps of buildings. Energy performance gaps are usually defined as the difference between energy demand as predicted during the planning phase and energy demand as measured during operation. It is assumed that the research strand, by reducing such gaps, contributes to the United Nations SDGs 7 (clean energy), 11 (sustainable cities) and 13 (climate action). However, in this conceptual article based on literature review we argue that blind spots in the current definition of energy performance gap research (embodied energy, gap between optimal and planned energy performance, greenhouse gas emissions, dynamic character) and weaknesses of frequently used scientific paradigms (techno-economic, psychological) may lead to the fact that the measures identified to eliminate energy-wasting and climate-damaging practices are of limited value. In fact, it is quite possible that conventional energy performance gap research even contributes to perpetuating such practices. The authors therefore call for a definition and paradigm shift in energy performance gap research, suggesting two broader definitions of the research subject (called life cycle energy performance gaps and climate performance gaps) and a promising alternative scientific paradigm (practice theory).
