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 2020 update introduced several critical changes compared to the previous 2008 version to account for climate change and better data collection: manual de dise%C3%B1o por viento cfe 2020 pdf capo
The "Isotacas" (wind speed maps) now use a 50-year return period with increased regional velocities based on more recent meteorological records. The primary goal of the CFE 2020 manual
New values for mean annual minimum temperatures significantly impact air density calculations, resulting in more accurate (and often higher) design wind speeds. manual de dise%C3%B1o por viento cfe 2020 pdf capo
