A bibliometric review of net zero energy building research 1995-2022
ENERGY AND BUILDINGS(2022)
摘要
This study aims to provide a comprehensive overview of three-decade research developments in the field of Net-Zero Energy Buildings (NZEBs) by using bibliometric analysis techniques. The specific objectives of this paper are to: (1) identify the most influential researchers, sources, and countries in this field; (2) identify the main thematic research focus areas and hot topics in the field; and (3) analyze the thematic evolution of NZEBs. VOSviewer software was used to realize the first two objectives while to meet the third objective, the SciMAT tool was employed to examine the thematic evolution of the field within three sub-periods (1995-2005; 2006-2015; 2016-2022). The results indicate that the main thematic areas of the field were initially limited to a few themes including 'environmental impact', 'green buildings', 'building materials', and 'fuel cells', and it expanded in the next periods by encompassing more themes. The results also showed that the field has now reached a certain level of consolidation by acknowledging the significance of three major themes: (1) buildings' energy conservation, (2) energy production and energy storage, and (3) methodological approach. Nevertheless, the evolutionary analysis points out that the field is still expanding with several themes newly emerged such as 'electric vehicles', 'zero-emission neighborhood' and 'smart buildings'. The findings offer a status-quo overview and critiques of research developments in NZEBs as well as emerging themes in the field that should be investigated by future studies. (C) 2022 Elsevier B.V.
