A Category 5 hurricane-proof log house is resistant to winds up to 245 miles per hour (394 km/h). Wall logs in such construction must be made of glued laminated timber and all other components of the house, including hurricane straps, must be hurricane-resistant.
After rigorous wind testing, the Insurance Institute for Business & Home Safety is recommending that homeowners make sure to close all interior doors, as well as all windows and exterior doors.
The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
Following rigorous scientific wind testing, the Insurance Institute for Business & Home Safety is urging homeowners to close all interior doors, in addition to windows and exterior doors.
Flow visualization of wind speed contours around a house Wind engineering covers the aerodynamic effects of buildings Damaged wind turbines due to hurricane Maria. Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage ...
Wind driven ventilation depends on wind behavior, on the interactions with the building envelope and on openings or other air exchange devices such as inlets or windcatchers. The knowledge of the urban climatology i.e. the wind around the buildings is crucial when evaluating the air quality and thermal comfort inside buildings as air and heat ...
A unique feature of the International Fujita scale compared to the Fujita or Enhanced Fujita scale is a new damage indicator based on measured wind speeds. For the IF scale , only wind speeds measured at or below 10 metres (11 yd) can be used to determine a rating.
[1] [2] In places where trees or structures impede the near-surface wind, the use of a constant 1/7 exponent may yield quite erroneous estimates, and the log wind profile is preferred. Even under neutral stability conditions, an exponent of 0.11 is more appropriate over open water (e.g., for offshore wind farms), than 0.143, [ 3 ] which is more ...
