Learn the SANS 10400-XA:2026 workflow

Fourteen practical guides take a project from initial setup to a reviewed calculation report. No account is required.
2026 workflow guidance, clearly separated from the standard

These guides explain the software, storey and tenancy workflow, and good data-entry practice. They do not reproduce or replace the official SANS document, product certification or professional review.
