The Manual de Diseño por Viento CFE 2020 in PDF format is far more than a regulatory text—it is a living technical tool that embodies decades of Mexican wind engineering expertise. Its clear organization, updated wind speed maps, dynamic analysis provisions, and practical examples make it accessible to students and indispensable to professionals. By following its guidelines, engineers can achieve the fundamental goal of structural design: safety under extreme loads without unnecessary material cost. As climate change intensifies wind-related hazards, the manual’s continued evolution will be vital. For now, any engineer or architect designing for the Mexican territory would be well-advised to keep a copy of this PDF on their workstation—and to know it thoroughly.
The Manual de Diseño por Viento (2020) by Comisión Federal de Electricidad (CFE) serves as the primary technical standard for wind design in Mexico, featuring updated isotach maps and increased regional wind speeds. This 514-page document improves upon the 2008 edition by providing specific design guidelines for renewable energy infrastructure and refined structural classification methods.

The Manual de Diseño de Obras Civiles - Diseño por Viento (2020)
published by the Comisión Federal de Electricidad (CFE) is the current technical standard for wind engineering in Mexico. This update replaced the previous 2008 edition and introduced significant technological advancements and expanded data. Key Features and Updates
The 2020 manual includes several critical updates to improve structural safety and economic efficiency:
Expanded Meteorological Data: Incorporates historical data from more weather stations across Mexico, Belize, and the US for better regional wind estimations.
New Isotach Maps: Features updated maps with 3-second gust regional wind speeds for different return periods (e.g., 10, 50, and 200 years) based on new probabilistic analyses.
Optimal Design Criteria: Introduces maps for "optimal wind speed" designed to minimize long-term economic losses based on a structure's importance. manual de diseno por viento cfe 2020 pdf
Structural Classification: Categorizes buildings into importance groups (A+, A, B, C) and four distinct response types based on their sensitivity to gusts and dynamic effects.
Renewable Energy Applications: Highlights specific design guidelines for structures used in renewable energy projects. Structure of the Manual
The manual is divided into several thematic sections for easy reference:
Chapter 1: General Criteria: Defines the scope, general requirements, importance classifications, and procedures for static and dynamic analysis. Chapter 2: Design Speed ( VDcap V sub cap D
): Details terrain categories, roughness factors, and the use of isotach maps.
Chapter 3: Static and Dynamic Analysis: Provides formulas for calculating pressure and forces on closed constructions, roofs, and flexible structures. Implementation Tools

The Manual de Diseño de Obras Civiles: Diseño por Viento 2020 (often cited as Chapter C.1.4) is the definitive technical standard for structural engineering in Mexico. Published by the Comisión Federal de Electricidad (CFE) in collaboration with the Instituto Nacional de Electricidad y Energías Limpias (INEEL), this update incorporates the latest meteorological data and technological advances to ensure structural safety against extreme wind events. Key Updates in the 2020 Edition
The 2020 manual introduces several critical changes compared to the previous 2008 version, reflecting more than a decade of new wind records and research:
Revised Isotach Maps: New wind speed maps (isotacas) for a 50-year return period show increased regional velocities in many areas due to more recent extreme weather data.
Temperature Adjustments: There are significant updates to the annual mean minimum temperature values ( Tacap T sub a
), which directly affect wind density calculations and final design pressure.
Updated Pressure Coefficients: The manual includes refined coefficients for various structural geometries, improving accuracy for buildings, industrial warehouses, and specialized infrastructure.
Renewable Energy Focus: New guidelines specifically address the design of structures for renewable energy use, such as wind turbine supports. Structure of the Manual However, the manual has been criticized for lacking
The document spans over 500 pages and is organized into chapters that guide engineers through the analysis process:

While the CFE manual shares conceptual frameworks with ASCE 7-16 and NBCC 2015, several distinct features stand out:
However, the manual has been criticized for lacking explicit guidance for tornado-resistant design (rare in Mexico) and for some non-building structures like solar panel arrays—a growing need in the renewable energy sector.

La CFE, siendo una entidad paraestatal, suele liberar este tipo de manuales técnicos a través de su portal de transparencia o en su sección de licitaciones y normas.
Nota: Evita sitios de terceros que puedan ofrecer versiones modificadas. Asegúrate de que el documento cuente con el sello oficial de la dirección de ingeniería de CFE.
La CFE ya trabaja en una actualización para 2025, basada en datos del clima espacial y cambio climático. Se anticipa un aumento del 15% en las velocidades de diseño para zonas costeras del Golfo de México. Por ello, familiarizarse ahora con el manual de diseño por viento CFE 2020 pdf es la mejor preparación para los próximos cambios.
Nota: Ten cuidado con sitios de dudosa procedencia. Muchos PDFs circulan con marcas de agua y páginas faltantes, lo que puede llevar a errores de cálculo catastróficos.
Si no encuentras la descarga directa, el Manual de CFE 2015 (similar al 2020 en estructura) es una alternativa aceptable mientras consigues la edición 2020.
