✅ Passed – All values match the Eurocode example to within rounding tolerance (±0.1%).
The sheet automatically calculates:
Validate the spreadsheet by running a benchmark problem from standard textbooks or established bodies like the Institution of Structural Engineers (IStructE). Cross-check the cell outputs against manually calculated values step-by-step. National Annex Integration
Excel sheets provide a level of clarity and control that is invaluable, but remember that the ultimate responsibility always lies with the engineer. Use these tools wisely, validate them thoroughly, and never compromise on safety or professional due diligence.

While our Excel sheet provides a reliable and accurate way to calculate wind loads, it's essential to note that it's not a substitute for professional engineering judgment and expertise. Additionally, the sheet is limited to simple structures and may not account for complex geometries or site-specific conditions.
From open sea (Category 0) to town terrains with closely spaced buildings (Category IV). This dictates the roughness factor ( Orography Factor (

: A truly comprehensive sheet will include dynamic lookup tables to retrieve the correct c_pe values from EN 1991-1-4. This applies to windward/leeward walls, roofs (flat, monopitch, duo-pitch), and even specialized elements like canopies. The sheet must also allow the user to choose between open, partially open, or closed buildings to apply the correct internal pressure coefficient ( c_pi ).
