Address in, code-correct ASCE 7-22 pressures out, and a report a plan reviewer trusts — in minutes, not an afternoon. Every coefficient traces to its ASCE section.
Three things a structural engineer actually needs from a wind load tool — and rarely gets together.
Type the project address. The design wind speed and risk-category factor arrive before you finish your coffee.
You sign the calc, so you should see the source of every value. The output shows each coefficient with its ASCE 7-22 citation.
The export reads like a calc package: inputs, assumptions, zone-by-zone pressures, and citations — formatted the way permit reviewers expect.
Each value in your output carries the ASCE 7-22 reference it was read from. No reverse-engineering, no faith required.
Section references shown for the ASCE 7-22 components & cladding workflow; figures adjust by procedure.
The same window-and-door schedule, done the old way versus done here.
Five engineering steps from a blank project to a signed-off package.
Enter the project address. Design wind speed and risk category resolve automatically.
Set exposure, mean roof height, and enclosure. The right ASCE figures are selected for you.
Add every opening as a component. Mulled assemblies are checked as a unit and per mullion.
Read zone-by-zone required pressures with each coefficient cited to ASCE 7-22.
Export PDF, .xlsx, CSV, or print — branded and ready for the permit set.
What changes when the repetitive work is automated and every value is sourced.
| What you care about | Here Best | By hand / spreadsheet |
|---|---|---|
| Time per schedule | Minutes | Half a day |
| Design wind speed | By address | Map lookup, by eye |
| GCp interpolation | Log-interp by area | By hand, error-prone |
| Coefficient citations | Every value sourced | You add them yourself |
| Florida HVHZ overrides | Applied automatically | Manual code cross-check |
| Multi-opening schedules | One pass, all zones | Re-key each component |
| AutoCAD handoff | .xlsx schedule | Rebuild the table |
| RFI defense | Point to the citation | Re-derive on the spot |
| PE sign-and-seal | Separate service, 50 states | Find your own PE |
No paid reviews — only verifiable facts behind the reports you sign.
Components and cladding for windows, doors, and storm shutters is live now. MWFRS (directional and envelope), roofs, parapets, overhangs, and solar are rolling out by category. Every calculator implements the current ASCE 7-22 provisions for that scope.
Yes. Every coefficient — Kz, Kzt, Kd, Ke, GCp, GCpi, and the velocity pressure q — is shown with the ASCE 7-22 section, table, or figure it came from. There is no black-box math, so a plan reviewer can trace any number back to the standard.
When the project address falls in a high-velocity hurricane zone, the calculator applies the Florida Building Code overrides for Miami-Dade, Broward, and Collier automatically, including the 4 ft edge-strip minimum. State certification modules exist for FL, LA, NC, SC, and HI.
Yes. Enter an address, city/state, or ZIP and the design wind speed is returned for the correct ASCE 7-22 risk category (I through IV) from a pre-built database of every U.S. ZIP, with special wind regions flagged.
Yes. Add every window, door, and shutter on the elevation as components, and the calculator returns zone-by-zone required pressures for the full schedule. Mulled assemblies are checked as a unit and at each tributary mullion.
PDF, Excel (.xlsx), CSV, and print. The .xlsx schedule drops straight into an AutoCAD window/door table workflow. Unlimited exports are included with no per-report fees, and you can add your company logo.
The software output is an engineering report, not a sealed document. PE sign-and-seal is a separate service: in-house for Florida projects up to three stories, and available in all 50 states through the firm's PE network.
The format carries a 100% permit-approval record across 24 years of operation. Because every coefficient is cited to its ASCE 7-22 source, reviewers can verify the math instead of taking it on faith.
Yes. The public wind speed lookup is free for any U.S. ZIP with no signup. A 7-day free trial then opens full component and report access so you can run a real project end to end.
Run your next window-and-door schedule address-first, with every coefficient cited and a report your reviewer already trusts. Start a 7-day trial — or check a ZIP on the free wind speed lookup first.
The free wind speed lookup covers every U.S. ZIP and applies Florida Building Code overrides for Miami-Dade, Broward, and Collier counties. No signup. No meter.
