Professional Wind Load Calculations in Minutes
Complete ASCE 7 compliant wind load analysis in 2-15 minutes with 99.8% first-time permit approval rate. Trusted by 10,000+ professionals for 24 years.
What Makes Us Different From Every Other Wind Load Calculator
Three exclusive capabilities that solve your biggest compliance headaches
Complete Certification Intelligence System
State Requirements + Product Verification = Zero Compliance Issues
The ONLY wind load calculator that knows what certifications YOUR state requires AND tracks your manufacturers/models to verify compliance automatically. Stop juggling spreadsheets and missing certifications.
State-Specific Requirements Built-In:
- Florida: FL# Product Approval / Miami-Dade NOA / FBC / HVHZ requirements
- Louisiana: LBC compliance / ICC-ES Evaluation Service Reports
- North Carolina: NCBC requirements / NFRC fenestration ratings
- South Carolina: SCBC compliance / AAMA architectural ratings
- Hawaii: CCPR (County Product Review) numbers / CBC compliance
- All 50 states + territories with automatic jurisdiction detection
Product Database & Verification:
- Store unlimited manufacturers and model numbers with complete certification tracking
- Automatic verification: Required vs. Certified pressure comparison with visual pass/fail
- Bulk certification: Certify multiple products simultaneously for massive time savings
- Complete traceability: Photo attachments, notes, and audit trails for inspections
- Jurisdiction intelligence: Handles special local requirements beyond state codes
Intelligent Location-Based Wind Analysis
We Know Your Project's EXACT Wind Requirements—Even When ASCE 7 Doesn't
Never miss a local wind requirement again. We automatically cross-reference 42,000+ locations against ASCE 7, state amendments, county ordinances, and special wind regions to ensure your design meets every applicable standard.
- 42,000+ Locations: Comprehensive US database with precise wind data for every project address
- Beyond ASCE 7 Tables: Miami-Dade enhanced velocities, special wind regions, county amendments automatically applied
- Local Jurisdiction Intelligence: Automatic detection of areas with requirements exceeding ASCE 7 minimums
- Coastal Zone Identification: Wind-borne debris regions, HVHZ designations, special exposure categories
- Multi-Standard Compliance: ASCE 7-22, IBC 2024, state amendments, and local ordinances—all cross-referenced
- Risk Category Adjustments: Automatic importance factor application for Categories I-IV
- Documentation Ready: Clear statement of which standards and jurisdictions apply to your project
Stop researching wind maps and county ordinances. Just tell us where you're building, and we'll tell you exactly what wind speeds you need—including those special local requirements that catch everyone else by surprise.
