Wind Exposure Zones in Ontario
Wind exposure zones describe geographic and structural conditions that influence wind pressure acting on roof systems. This regional model extends the Climate Stress Load Models.
Primary Wind Influences
- Open terrain and elevation
- Proximity to large water bodies
- Urban vs rural exposure
- Building height and orientation
Zone Characteristics
- Consistent directional loading
- Localized pressure intensification
- Increased storm-event variability
System-Level Effects
- Pressure-driven moisture movement
- Increased fatigue at edges and transitions
- Interaction with snow and ice accretion
