Building-Integrated Carbon Sequestration Techniques: Towards Mitigating Climate Change

This paper provides an overview of building-integrated Carbon Sequestration (CS) techniques focusing on their potential environmental impact and associated costs. CS techniques are classified into three categories: 1) Biotic (Green Roofs, Vertical Greenery Systems (VGS), and Algae Facades); 2) Materials (carbon-negative and carbon absorbing building materials); and 3) Equipment (filter towers). By analyzing and summarizing each CS technique based on performance indicators like prerequisites, CS potential, costs and area required, it was found that Biotic techniques can be applied to a structure’s roof and facades for a large range of projects having low to high budgets. A comparative analysis shows the CS potential associated with the Biotic CS techniques to allow architects and designers to evaluate these technologies and analyze their integration potential in architectural practice.
