The Engineer's Role in Improving Housing Resilience


Build Change, an award winning non-profit social enterprise that works with people to design and build disaster-resistant houses and schools, is innovating on its experiences over the past 17 years in order to support large scale post-disaster rebuilding and pre-disaster mitigation efforts in the Asia Pacific region, Latin America, and the Caribbean. This presentation will feature a description of Build Change’s work and Theory of Change; its context relative to the natural disasters and community awareness in Colombia, Haiti and the Caribbean, the Philippines, Nepal and Indonesia; and the recent innovations developed by Build Change, with perspective from past experiences. It will also feature new technologies and methodologies that have been developed in key aspects of their work, with contributions from American engineers in several cases. The presentation will also feature an introduction to Build Change’s new Resilient Housing Guide, which documents the methodology developed by Build Change to promote resilient housing construction.
