Expert Insights on Integrating Vertical Greening Systems into Historic Buildings: Survey Findings

Integrating vertical greening systems (VGS) into historic buildings presents both advantages and challenges related to heritage conservation and urban sustainability. VGS contribute environmental benefits, such as reducing surface temperatures, improving air quality, and supporting biodiversity. However, their implementation raises concerns about potential risks to architectural integrity and cultural heritage.

This study explores expert perspectives on the implementation of VGS in historic buildings, focusing on the environmental, cultural, social, economic, legal, and technical aspects. Using a mixed-methods approach, the research combines insights from a literature review with survey data gathered from experts in vertical greening and heritage conservation. Both open-ended and closed-ended responses were analyzed to identify variations in expert opinions.

The findings reveal a general recognition of the environmental benefits of VGS; however, significant technical and cultural concerns present obstacles to widespread adoption. The results emphasize the need for increased awareness and structured information for stakeholders to promote a balanced approach that maximizes the advantages of VGS while addressing the challenges associated with historic architecture.
