Methodological framework for impact evaluation of Building-Integrated Greenery (BIG-impact).

Area of Science:

• Urban Ecology
• Sustainable Architecture
• Environmental Science

Background:

• Building-Integrated Greenery (BIG) systems, including green roofs, walls, and facades, are crucial nature-based solutions for urban renaturing where space is limited.
• These systems provide vital ecosystem services like urban heat island mitigation, noise reduction, biodiversity support, and improved insulation.
• The lack of impact evaluation for real-world BIG implementations hinders cost-benefit analyses and jeopardizes their long-term sustainability.

Purpose of the Study:

• To introduce a comprehensive and practical tool for evaluating the impact of Building-Integrated Greenery systems.
• To address the gap in assessing the ecosystem services provided by BIG systems in real-world applications.
• To facilitate informed decision-making and promote the long-term sustainability of BIG systems.

Main Methods:

• Development of a novel, holistic assessment method for BIG systems' impact.
• Consideration of European and global references for building-integrated systems impact assessment.
• Design for easy replication in any real project, enabling stakeholder collaboration.

Main Results:

• The presented method offers a holistic assessment of BIG systems' impact in real cases.
• It facilitates the evaluation of provided ecosystem services, addressing a critical gap in current practices.
• The tool is designed for broad applicability and stakeholder engagement.

Conclusions:

• The developed method provides a unique and practical approach to evaluating the impact of Building-Integrated Greenery.
• This evaluation is essential for justifying maintenance, ensuring long-term sustainability, and maximizing urban ecosystem benefits.
• The tool supports informed decision-making for the widespread adoption of sustainable urban greening strategies.
