Comprehensive review of building-integrated photovoltaics in the renovation of heritage buildings
Irene Del Hierro López, Lorenzo Olivieri
Abstract
The escalating global climate crisis necessitates immediate action to mitigate its adverse impacts on societal and environmental systems, particularly through reducing emissions associated with the built environment. Traditional and historic buildings , which often exhibit significantly higher energy consumption compared to modern standards, pose a unique challenge in meeting emission reduction targets. Building-integrated photovoltaic (BIPV) systems present a promising solution, combining renewable energy generation with the preservation of historical and cultural heritage. This study examines 41 case studies of historic buildings that have integrated BIPV systems, with a focus on achieving harmonious integration within their built environments. The findings reveal that the majority of these projects are located in Europe, with rooftops serving as the predominant site for system installations. Additionally, the analysis underscores a significant correlation between a building's heritage protection status and the placement of photovoltaic systems . The objective of this research is to broaden awareness and increase the visibility of BIPV systems as a viable approach for the sustainable renovation of historic and traditional buildings. The results demonstrate that it is both feasible and effective to balance heritage conservation with the integration of photovoltaic technology , offering a sustainable pathway to enhance energy efficiency in culturally significant structures.
