Carbon Sequestration and Habitat Provisioning through Building-Integrated Vegetation: A Global Survey of Experts

Carbon sequestration (CS) and habitat provisioning (HP) through building-integrated vegetation are interlinked approaches that could potentially reduce climate change and biodiversity loss attributed to the built environment. However, a practical approach is required to integrate CS and HP into building design. A two-stage approach was undertaken in this research; firstly, preparing a conceptual framework from an extensive literature review and, secondly, gauging the perspective of building industry experts on that framework through a survey. The survey was designed to determine expert opinion related to establishing the data gathering approaches, progressing to identifying strategies and methods to quantify them, and finally, monitoring performance indicators for achieving CS and HP goals. The results of descriptive analyses performed after data collection indicate a notable difference in opinions between built environment professionals (group A) and environmental scientists and researchers (group B). The findings indicate that respondents emphasized maintaining vegetation in order to maximize CS rates and biodiversity levels. Moreover, spatial ecology considerations, including landscape-level parameters (vegetative area coverage, habitat availability, quality, and connectivity) and species-specific parameters (species selection based on their CS rates and habitat requirements for keystone species), must be analyzed while designing buildings for vegetation-based CS and HP.
