Abstract
As climate change accelerates, design strategies must adapt to address the increasing frequency and intensity of rainwater events and urban flooding. Projects today face heightened demands for on-site stormwater management, reduced discharge allowances to municipal sewer systems, and a greater risk of water-related damage: all of which call for innovative, integrated solutions.
Building envelope strategies play a critical role in mitigating these risks. Solutions such as below-grade waterproofing (tanking), advanced drainage for window and wall systems, and blue or green roofs help manage rainwater more effectively at the source. When paired with site-level interventions, like water detention systems and flood barriers, they form a comprehensive approach to climate resilience.
The key challenge is selecting systems that not only meet current performance standards but also provide long-term durability and value. It’s about striking the right balance between protection, cost-effectiveness, and peace of mind.
For a deeper dive of these strategies, refer to David Fooke’s presentation notes from the 2024 AIBC Conference.
