1. Wind Hazard Modeling and the HAZUS Wind Model

2. Major Stakeholders Local, state and federal government agencies Humanitarian organizations Insurance industry Businesses and private citizens

3. Why Model Wind Damage? Understand/Prepare for Building Damage Understand/Prepare for Sheltering Requirements Understand/Prepare for Emergency Management Response Understand Economic Ramifications Provide Justification for Building Code Changes

4. Types of Damage and Loss Models Holistic, Actualized Cost Models Meteorological Models Load vs. Resistance Structural Damage Model Tree Damage Models Windborne Debris Damage Models Loss Models

5. “The HAZUS-MH Hurricane Model is designed to produce loss estimates for use by federal, state, regional and local governments in planning for hurricane risk mitigation, emergency preparedness, response and recovery.” -HAZUS Technical Manual

6. About HAZUS Hazards United States (Multi-hazard) Product of National Institute of Building Sciences (NIBS) and Federal Emergency Management Agency (FEMA) Earthquake Model released in 1997 HAZUS-MH released in 2003 Flood Model and Hurricane Model Geographical Information System (GIS)-Based Model

12. Residential Damage States Damage StateQualitative Damage Description Roof Cover Failure Window Door Failures Roof Deck Missile Impacts on Walls Roof Structure Failure Wall Structure Failure 0No Damage or Very Minor Damage Little or no visible damage from the outside. No broken windows, or failed roof deck. Minimal loss of roof cover, with no or very limited water penetration. ≤2%No 1Minor Damage Maximum of one broken window, door or garage door. Moderate roof cover loss that can be covered to prevent additional water entering the building. Marks or dents on walls requiring painting or patching for repair. >2% and ≤15% One window, door, or garage door failure No<5 impacts No 2Moderate Damage Major roof cover damage, moderate window breakage. Minor roof sheathing failure. Some resulting damage to interior of building from water. >15% and ≤50% > one and ≤ the larger or 20% &3 1 to 3 panels Typically 5 to 10 impacts No 3Severe Damage Major window damage or roof sheathing loss.
