Designing an Earthship style Eco Village in Taiwan, Asia, to resist Typhoon (Cyclone , Hurricane) strength winds.

So, what I wanted to do here, looking at Designing an Eco Village in Taiwan, is get a basic understanding of the forces involved with strong Typhoon / Cyclone / Hurricane winds, using a model of an Earthship style building

So you can think of this as a back-of-the-envelope calculation…..in a video ;-)

With a little Google-Fu, you can find some great resources available online, to punch in some numbers & get some figures out.

I'm not a qualified structural engineer or anything close, so this information does not constitute advice in any way - but might help you if you're interested in a little bit of Sunday Enginerding.  

This is by no means an exhaustive study of the effects of wind speed on buildings, but should help to give a basic idea of what’s going on, and the forces involved

Structural Considerations
Structural methods to mitigate Typhoon-Strength wind speeds including 
    1. structural reinforcing, 
    2. cyclone bolts / hurricane straps
    3. reducing exposure
    4. shutters to prevent building ‘exploding’ by keeping window openings structurally sound.
    5. Size of window door openings.
Site Considerations
    1. Building placement within site
    2. Prevailing storm directions, including less-frequent Typhoon occurences
    3. Terrain including Valleys or ‘funnels’
    4. Vegetation, planting, tree cover
