Mitigation Matters:The Drive Toward Resilience
Debra Ballen, General Counsel and SVP Public Policy
IBHS MissionTo conduct objective, scientific research to identify
and promote effective actions that strengthen homes,
businesses and communities against natural disasters
and other causes of loss.
Focus on the Roof
2010 High Wind Demo
High Wind Demo 2012
2017 Atlantic Hurricane Season
• Harvey, Irma and Maria collectively affected 10 states and 5 U.S. territories ≈ 8 percent of U.S. population
• ≥ $200 B in losses, ≈ 30% insured
• Flood losses huge, but many uninsured
• FL building codes credited with reducing damage and disruption
• Lack of power one of biggest barriers to recovery
Close the Doors on Irma
October 2017 California Wildfires
• 43 fatalities, ≥ $10 B in insured property losses, ≈ 5,000 homes destroyed = worst in U.S. history
• High winds caused ember spread to urban areas = widespread destruction of neighborhoods
• State housing crisis complicates recovery for homes, businesses and communities

Maureen F.
• Political gridlock (especially in Congress) prevents even consensus legislation from advancing
• Budget rules and short-term outlooks prevent spending $ today to save $$$$ in the future and value post-disaster aid over pre-disaster mitigation
• Pre- and post-disaster aid processes are inefficient
• It is politically easier to suppress insurance rates than reduce property risk
• Home builders and realtors are more directly politically engaged than insurers and mitigation allies
Political Challenges
Moving Forward
• Leaders can galvanize public attitudes toward property risk
• Clear, consistent messages needed for public education
• We must understand benefits/risks of new technologies
• Relationship between natural and built environment influences risk
• Focus on “no regrets” strategies for mitigation and insurance

• Basic purpose of buildings• Building types and considerations• Overview of design
considerations• Climate change• Durability and redundancy
• Teaching, training and apprenticeship
• Provide shelter• Separate and protect us from
outside environment• Life safety• Building science considerations• User experience
* DOE Climate Map
• Change in type of precipitation events• Increased volume/shorter duration• More severe storms/higher winds• Flooding
• Solar considerations• Increased radiation• Examine SHGC and window films
• Need for improved durability and redundancy
• Review of macro and micro climate• Understand the climate zone• Rain fall volume considerations
• Micro climate specific to your site• Review of site topography• Development density• Neighboring existing buildings and
planned future development
• Existing building versus new construction
• Orientation of building and considerations by elevation
• Responsiveness of systems• Controls • How it reacts to the environment
