The primary goal of the CFE 2020 manual is to establish uniform criteria for calculating wind loads on structures across Mexico, a country with diverse wind climates including hurricane-prone coasts and high-altitude plateaus. Unlike many local building codes that are city-specific, the CFE manual offers a national standard often adopted by municipalities that lack their own specialized regulations.
The published by the Comisión Federal de Electricidad (CFE) is the definitive technical guide for structural wind engineering in Mexico. This 514-page document provides the rigorous mathematical and empirical frameworks necessary to ensure that infrastructure—from simple warehouses to complex power plants—can withstand aerodynamic forces. Core Objectives of the 2020 Manual
The manual uses a specific formula to determine the wind speed a structure must be designed to resist:
New values for mean annual minimum temperatures significantly impact air density calculations, resulting in more accurate (and often higher) design wind speeds.
(Exposure/Size Factor): Accounts for terrain roughness (e.g., urban vs. open sea) and the height of the structure. Sistema Viento | Gerencia de Ingeniería Civil
(Topographic Factor): Adjusts for local terrain features like hills or cliffs. FAcap F sub cap A
Buildings are also classified by their response to wind (Types 1 to 4), ranging from rigid structures to those highly sensitive to dynamic effects. Calculating Design Wind Speed ( VDcap V sub cap D )
